Yoga 2 Pro vs Dell XPS 11

From what I can tell in the current marketplace, these two tablets are at the top of the heap and the only true competition for each other.
The Yoga 2 Pro and Dell XPS 11 each exceed the other in numerous metrics.
Here is a quick comparison:
1) Price - Yoga 2 Pro gives you an i5 with 128 gb SSD for $999.  The XPS gives you only an i3 with an 80 gb SSD for that price.
2) Ports - XPS 11 wins this one with 2 USB 3.0 ports vs the Y2P 1 USB 3.2 andd 1 USB 2.0.
3) Screen - Y2P offers more real estate and higher PPI by 20 points than XPS 11.
4) Portability - XPS 11 is thinner, has a smaller footprint and is 1/2 pound lighter.
5) Keyboard - Y2P offers an excellent real keyboard.  XPS offers a weird kind of flat, non-depressable surface that offers haptic feedback but apparently is hard to type fast on, especially if you have fingernails.
6) Active Digitizer - Easy win for XPS 11 here.  Big fumble by Y2P.
7) Best for Business - Depends.  Bigger better screen and better keyboard vs thinner, lighter, smaller footprint and a pen.  Some Legacy programs such as Access with forms designed for desktops may be a bit small on the XPS.
8) Best Desktop Replacement - Have to give this to the Y2P based upon the larger screen.
9) Wifi - This one goes to the XPS11 as it offers dual channel AC.
So it's a tough call.  What do you guys think?  IMHO if the Y2P had included an active digiitizer this would have been a no-contest win for the Y2P.

To do a proper comparison, items that are purely personal preference pieces (size of display, keyboard style etc) should be left out. When this is done, it really is a no brainer. The XPS 11 is hands down the superior machine. This is not to say that one machine will be more compatible or a better match for a particular person based on those personal preference items or perceptions of them. Everyone has a different liking as to what is an ideal display size or keyboard style for them. That is also why many people use a docking station setup so they can use full size keyboards and large 27" screens while working in the office for 8 plus hours. Price difference between the 2 machines is not siginificant and not a consideration if the superior XPS 11 machine has additional value that justifies it to the owner That said, there are other significant core advantages associated with the XPS 11 not mentioned. The XPS 11 uses state of the art NBT Corning Gorilla glass. If you read up on what that means you will see why that is hugh and also why there is additional cost to manufacture with it. The Y2P uses the "U" series processor and not the lower voltage "Y" series used by the XPS 11. The "Y" series is better suited to small form factor ultrabooks and power efficiency. The XPS 11 has a higher display NITS rating of 400. This is at the top of its class and is extremely important for those that may use them in an outdoor mobile activity. The XPS 11 is constructed of carbon fiber and not of the cheaper and much weaker external plastic construction of the Y2P. At 11.6" and 2.5 pounds, the XPS 11 is closer to a comfortable large tablet usage size than a 13" and half pound heavier Y2P. Given the wireless AC standard, it is becoming poor corporate judgement to release a new ultrabook that does not support it. For Lenovo to release an ultrabook that does not support dual band wireless when dual band access points have been in homes for years is completely unacceptable. Same goes with no pen support when the machine is a convertible hybrid. The XPS 11 material comprising the flat keyboard suface grips better when face down than hard plastic buttons. The closer you look at the engineering, design considerations, materials used, the more it becomes clear as to which platform is better built and thought through. Dell has had the luxury of analyzing Lenovo's Yoga build history and has done an incredible job addressing the serious short comings in the Yoga series. That is a significant achievement since the Yoga is still a very good overall machine.

  • Should I pick the Macbook Air/Pro or the Dell XPS 13?

    Hello everyone!
    I'm a 10th grade student in a international school, where we are allowed to use laptops instead of our regular notebooks. In my class no one uses a notebook, so I would be the first one.
    My idea came from the fact that I broke my arm, and am unable to write normally for the next 3 months, as my hand is in a cast. I am currently writing on my iPad, which is nice, as I can only use my left hand for typing. I didn't really think much of it, but after few days I realised how easy it is to type on a tablet instead of on a piece of paper.
    I took my exams on a PC and I was easily able to write with my left hand only. The experience was much better, as I was able to erase all my mistakes/ rewrite someting I didn't like… but let's get to the point.
    After I finish my iGCSE's, I'll be going to the IB diploma programme. It is very rigorous and requires a lot of work, so a laptop would be very helpful. The three laptops I want to choose  between are:
    1. 13" Macbook Air
    2. 13" Macbook Pro
    3. New Dell XPS 2015 13" (http://www.dell.com/us/p/xps-13-9333/pd?oc=fncwp1512h)
    Now I know about the rumors of the new Macbook Air 12" with retina display, but the idea of having one port only doesn't appeal to me. I currently have an iMac 27" late 2013, along with an iPad and an iPhone. It is better to stick to apple just for the whole sync. between all devices, or is the Dell better in terms of performance? The ultrabook would be used for typing essays, editing videos (I'm doing film at school, so we get assignments like that pretty often) and of course web browsing. Gaming isn't really a priority, but to play some easy-going games such as garry's mod or turbo dismount on the go would be nice.
    So what do you guys this is the best pick? I want the laptop to last another three years before I go to uni, and that's the reason I want to go for either the mid-spec. MacBook Pro/Air or the fully spec. Dell XPS 13. Price plays a role here, as I can only pay max. 1500$ for it, so I cannot afford the fully spec. MacBook Pro 13".
    Ps. I really like the touchscreen in the Dell XPS 13, but does it affect the battery life much? It's really important that it lasts at least 8 hours a day, as I start school really early in the morning, and finish late in the afternoon.
    Thank you for your answer,

  • Yoga 2 Pro with external Dell P2414H monitor - Win 8.1 issues

    I have a UK model Yoga 2 Pro (Core i7/256GB/8GB). Generally happy with it but I have one weird issue that is annoying me.
    The system is fully patched including all Windows updates and latest Lenovo BIOS and drivers.
    At work I have a Dell P2414H monitor connected to my Yoga 2 Pro (micro HDMI to HDMI cable into an HDMI to DVI adapter plugged into the monitor's DVI port).
    Windows recognises the Dell monitor in display settings. I can extend my desktop onto it. I can run the Cleartype Tuner and tune the laptop screen and Dell cleartype settings independently. All good so far...
    In Taskbar and Navigation Properties (right click on the taskbar and select Properties) I expect to see a "Multiple Displays" section on the Taskbar tab with a setting that allows me to extend the taskbar across both screens, as per this link: http://windows.microsoft.com/en-gb/windows-8/how-connect-multiple-monitors.
    However, whatever I try I never see the "Multiple Displays" settings in Taskbar Properties. I have rebooted with the external screen connected and not connected and tried everything else I can think of but all to no avail.
    Is anyone else seeing a similar issue with an external monitor connected to their Yoga 2 Pro?

    Discovered that if If I make the external monitor my primary screen, not the laptop, then Windows gives me the Multiple Monitor Taskbar settings back. However, I then have screen scaling issues so dialogues and the task bar etc. on the Yoga screen are tiny. Not ideal...

  • How does Premiere Pro perform on a Dell XPS 15?

    Trying to establish if Premiere Pro (via a full subscription of the Creative Cloud suite for $49.99) is worth the investment when I'm working on a Dell XPS 15 laptop with 16 GB of RAM (rest of the hardware is standard top-of-the line XPS 15 options, i.e. quad core processor, NVIDIA video card, etc).  I've been using Adobe Premiere Elements and a ton of 4K GoPro footage with some pretty meaningful slowdown when rendering.  This could be par for the course, but I'd just as quickly go with another video editing program like Sony Vegas for my purposes and pay far less, but of course also get far less in terms of Adobe power.
    Also - this laptop does not have a 7200rpm hard drive (the one that isn't solid state, which is 32GB by itself).  It's 1TB but likely in the high 5's instead...not sure if I can use a faster external hard drive and meet optimal spec requirements to preserve video as much as possible.  Please advise.

    My inquiry is actually to the reverse of your suggestion; I have the laptop, but I hadn't yet purchased the Adobe Cloud Creative Suite.  Though I went ahead and did so this week.  The XPS 15 was chosen for its lightweight aluminum / carbon fiber construction, Intel Core i7 processor, 16 GB of RAM, 1TB of hard drive space for ample storage, and the SSD for active programs so things are quick to launch.  I've had very few complaints with the laptop itself, having used only Adobe Premiere Elements (which came with the purchase) and the GoPro app for developing a few videos of aerial GoPro footage.  It has served its purpose; I'm not a professional doing this work to sustain my living - it's a hobby to me, though I aim to have the best possible quality in all things when possible. Granted, I could've spent the same amount of money, or perhaps a little more, and gotten the best and fastest desktop arrangement money could buy for my purposes with ample more power and performance, but I wanted 100% mobility for all my equipment (drone, camera, and video production unit).  Gives-and-takes in everything, of course - the biggest consequence has been rendering, but in this forum that probably goes without saying, and though not awesome, it's livable even when using GoPro 4K codec as BartonGarrett256 wisely mentions.
    Nevertheless, Adobe Premiere has been doing well so far...certainly better than the Elements application in terms of both performance and capability (naturally).  I haven't gotten to After Effects yet, though I do love having that at my whim with my Cloud subscription which is, to me, well worth what you get for what you pay if you know you'll be using multiple applications for the foreseeable future.  The days of paying hundreds of dollars for one application are ending, as well they should in my opinion. 
    Though I'm open-minded to what one might suggest for the most powerful laptop on the market - 8 core is honestly news to me.  My XPS was purchase in December 2014 and it had the best processor Dell could offer with the XPS model.  I almost went with an Alienware, but it would've been a lot bulkier, and the display was archaic in a world moving more and more toward crystal clarity wherever possible.
    One other setback I would love advice / opinions on - the 1TB drive that came with the XPS is not 7000+ in speed...I recall it being in the 5's.  Can I remedy this with an external drive that does have the higher speeds cited as optimal for the Adobe video editing suite?

  • Lenovo Yoga 3 Pro Ultrabook mit AnyPen

    Hallo, ich spiel seit einiger Zeit mit dem Gedanken mit ein Taplet zuzulegen. Ich finde dies für die Kleinichkeiten des Alltags ( Zeitung, soziales, Spielereien ) sehr praktisch. Desweitern möchte ich mich damit anfreunden mit dem Ding zu arbeiten. Da ich all mein Lernstoff für das Studium zusätzlich in Digitaler Form habe/bekomme wäre es auch sicherlich von Vorteil damit zu lernen. Auch rechnerisch/zeichnerisch möchte ich damit arbeiten. Meine Dozenten leben es vor ohne Papier, Stift oder Tafel, dafür mit Laptop, Taplet und Beamer zu arbeiten. Es gibt hier schließlich ettliche Programme / Apps mit denen sich auch Mathe oder Physik sauber auf dem Taplet niederschreiben lassen.
    Jedoch möchte ich auf den Laptop nicht verzichten. Da ich sowieso einen neuen benötige möchte ich die zwei Anschaffungen miteinander verbinden und bin auf der suche nach einem convertibl Ultrabook. Ich habe mich schon durch einige Testberichte gelesen und laut diesen ist der Favorit zwischen Dell XPS 12 und Lenovo Yoga 2 Pro und Lenovo Yoga 3 Pro das 3 Pro.
    Nun zur Frage: Bei allen Testberichten konnte ich keine brauchbare Info über eine Bedinung mit einem Stift lesen. Bei Lenovo ist es die AnyPen Technologie die bei ziemlich allen Taplets funktioniert aber ich nicht weis ob dies auch bei den Ultrabooks zutrifft. Ohne Stifteingabe kann man meiner Meinung nach die ganze Lernerei vergessen gerade bei Mathe und Physik. Kann mir darüber jemand eine brauchbare Info geben die mir die Qual der Wahl nimmt ??
    Danke im Voraus

  • Dismal performance of new Yoga 3 pro (with Win 8.1): will Win 10 improve it?

    Dear all,  As I said in another topic, coming from years of Macbooks, I just bought a new Yoga pro 3 (the version with the latest processor, 8Go am, 512 G SSD) and I find it very slow in daily usage. I usually have Chrome, Outlook open all the time as well as Evernote and when I try to play Hearthstone in the mean time, it gets very slow: the game (which i not very demanding) lags (and not because of internet issues), and if I want to switch to Chrome and browse, it is agonizingly slow. Sometimes, I even have the impression that loading pages is slower than on my Maacbook (tried both at work where the Wifi is quite fast and at home). I have run onekey optimizer, removed some unecessary programs  like MacAfee (truthfully, I have added stuff in the background like Avast, Listary, launchy but nothing big...) I wonder what else I can do to improve the performan. Maybe remove Aero? Also, how can I checck the performance ? I looked at system monitor while the system was slow and it was telling me that the processor was used at something like 80% but nothing more, and memory about 50%. I am wondering wether installing Windows 10 might improve the performance. Any feedback?  Thanks for your help!I have to admit that I am a bit dispirited and I am considering  sending it back (and maybe try a Dell XPS, because I really would like to try Windows 10). I don't have huge computing needs anymore (apart from some excel of Rstudio from times to times, but I haven't even tried that on the Yoga...) but if even those needs cannot be satisfied...

    Specifically Chrome, Windows 10 is a huge improvement. This may be due to the improvements with DPI scaling and GPU optimizations.
    I've done a couple of custom, highly not recommended changes to see if I can get around the thermal limitations of the system, but it looks like it can only be tweaked through a UEFI update. In the end, disabling the thermal system in the BIOS aided the throttling impact.
    The performance sits solely on the Core M chip. Used in other machines (noteably, the Macbook 2015), this architecture has been criticized for sacrificing performance for its low power profile. However, this is also its greatest benefit. I can watch Netflix on my Y3P for at least 5 hours on battery, where other machines would maybe give me 2 hours. When a program uses the hardware acceleration on the HD 5300 built into the CPU, it works great. It's no performance GPU, however, it handles format decoding amazingly. However, if there's an app not optimized for GPUs, the CPU has to render a display with a resolution of 3200x1800, 4 times the size of a 1600x900 display. This is why Chrome is honestly a disaster in Windows 8.1. It's not optimized for Intel GPUs.
    If you want to stick with Windows 8.1, try using IE. You'll lose add-on support, but it runs great. If you move to Windows 10, Microsoft Edge will be getting add-on support in the future.

  • Poorly designed Yoga 3 Pro keyboard workaround

    Several users have been griping about the keyboard of the Yoga 3 Pro. Also certain reviewers have lambasted it (e.g. Gizmodo).
    First, the physical side of it is lacking for the typical quality you expect from premium Lenovo laptops (e.g. Thinkpad). The keys do not travel much and it is easy to make mistakes -- I would say my typing errors have increased on the magnitude of 50% versus a X series Thinkpad (pre-chiclet keys).
    Second, and the main point of this post, is that several keys are either missing (e.g. Insert) or relegated to Fn key combinations (F1 through to F12, Home and End). Meanwhile, there is AMPLE room for more keys in this form factor. For example on X series Thinkpads, they had keys right up to the edge of the device, and were able to put in a full 2 rows of Ins/Del Home/End PgUp/PgDn, like on a full-sized keyboard.
    As a result, typing on this keyboard is a real pain both physically, and in software terms since certain OS functions ask you to press keys that don't exist (e.g. Insert on the pre-boot Bitlocker screen -- sorry no Insert key!). Certain common keyboard commands become awkward now because of needing to add in the extra Fn+ combination (e.g. ALT+F4 to close a program, or F5 to refresh a web page).
    But by far one of the most annoying features is co-locating Home with PgUp and End with PgDn, i.e. you need to press Fn+PgUp to get Home. Home/End is a very efficient mechanism in wordprocessing to quickly get to the beginning and end of sentences, beginning and end of cells in Excel when editing formulas, etc. F2 to quickly edit a cell in Excel without clicking the mouse -- now you must use a combination to get to it. If you do frequent word processing, this keyboard will frustrate you as a result.
    Meanwhile, Print Screen gets a full key?!? I could see that key as one becoming a Fn combination, since there is no potential for a user to frequently and repeatedly press Print Screen. I seriously wonder if the person/team that designed this layout tested it at all with users "in the field" who actually TYPE.
    Anyway, there is a workaround of sorts depending on which keys you prefer to have direct access to. You can remap keys using the Windows registry and something called a Scancode Map.
    For example, I myself have noticed that Home/End are more important for me than PgUp/PgDn in terms of quick access, as I do use them extensively for editing documents. So, for example, you can use the registry to remap those keys and switch them around -- that is, Home to PgUp, PgUp to Home, End to PgDn, PgDn to End. So now, when you press the PgUp key, you are actually pressing Home.
    If you don't use Caps Lock or Print Screen for example, you can reassign them to other keys you do (e.g. Insert, or any other key actually).
    The process is described in the link below, and the author has a specific example of remapping the Home/PgUp, End/PgDn keys:
    http://www.thatsgeeky.com/2010/11/keyboard-annoyances/

    I tried that I got some sort of error saying it's not compatible with my system.  I ended up doing a restore, and one by one tracking down which program is needed in order for the system to disable the keyboard and trackpad appropriately.
    It ended up being Lenovo Harmony:
    http://download.lenovo.com/consumer/mobiles/wwha020e.exe
    It seems you need Harmony if you'd like them to be disabled in stand, tent, and tablet mode.
    Thanks for the help, anyway.

  • Yoga 3 Pro Touchpad "Momentum" or "Inertia"

    The Yoga 3 Pro appears to use a Synaptics touchpad driver. I have used a Dell at work and an HP at home both using Synaptics touchpads as well as my wife's Toshiba Satellite. The device drivers for these offered "Momentum" which, once you get used to, you can't live without. Momentum allows you to flick your finger a little in a direction and the mouse cursor will continue in that direction across the screen until you touch the touchpad again which "catches" or stops the cursor movement and you can resume moving it to its final destination. The Lenovo Yoga 3 "Synaptics" touchpad driver does not offer this option in its settings. Does anyone know of updated drivers that will provide this capability?
    I have looked a little deeper (into the registry) of the other computers and have found some settings that seem to enable it in the current driver (Synaptics 18.0.7.85) - MomentumMotion (setting to 1 enables it) as well as MomentumMotionFriction. No wonder it is disabled by default and no setting in the GUI to turn it on - it is very erratic and barely works (sometimes works a little if you make a very long pass across the touchpad and not too quickly before letting go). It is very unusable as it stands in this driver.
    If anyone has any information on how to enable this feature properly through a proper driver that works, please let me know. This one feature really makes or breaks using a touch pad all day without getting so "tired" in the hands, fingers, and wrist. Even though it is a touch screen, it is just awkward to poke at the screen when in laptop mode with such a nice and light laptop

    I will be doing a video review on my experience soon but here are some points I can tell you already -
    1) It is a great travelling companion, movies, videos, songs, small gaming is all perfect.
    2) Battery life is really nice, I watched 3.5 hour long Lord of the rings and still had about 60% left
    3) Pretty light and rotates 360 degrees, very comfortable to use in any and every mode.
    4) Does not get hot, remains cool.
    5) Exquisite looks especially the Bright orange color, which is my fav.
    6) Screen is beautiful and everything is crisp (I use it at 1080p)
    7) Some apps are very useful like ShareIt, transfer data from android, iphone etc in seconds over a wifi network.
    8) Performance is good for browsing as well.
    9) Boots in 3-5 seconds
    10) Keyoard is backlit and very nice but shallow, trackpad is an absolute delight.
    2 finger taps, 2 finger swipes, 3 finger swipes, 2 finger zoom, 2 finger scrolling of pages, everything is smooth and responsive.
    11) Sound quality is awesome as well, very loud and clear. Enough bass to provide enjoyable experience.
    What you should not expect -
    1) Heavy graphics intensive tasks.
    2) Lags a bit on some web pages scrolling (NOT noticeable)
    3) Some software which are useless and can be uninstalled.
    I typed this whole post on my Yoga 3 Pro and it is a great for me to type on this beauty.
    Going to watch a movie now.
    Current System - Lenovo Y510P, GT755M SLI, 8GB RAM, 1TB HDD + 24GB SSD
    When your plans fail, your Real Story begins!!

  • Yoga 2 Pro: Touchpad doesn't disable in Tablet or Stand

    When I flip to tablet or stand mode (i even get the toast notification that it's switched), the touchpad doesn't disable. I am still able to move the pointer and click. The keyboard however is disabled.
    I have installed the bios update, energy manager thing, and latest firmware from Synpatics.
    Anyone else have this issue?

    I understand you and the users frustration. I agree that sometimes things just do not work as they should. Anyway, thanks for bringing up the issues. I'll need to check into the trackpad thread before escalate this case in full to engineering.
    In regard to the WiFi issue, we had escalated this case much earlier but due to this model comes with different wifi card as well as situation changes based on different routers used, it was very difficult for the enginering team to pin point out the real root case. I'm sorry that it haas been dragged this long. But based on the information I have currently, our engineering team is testing on a beta driver provided by Intel and we're also trying to get affected machines as a sample for our further analysis. I'll need to catch up with a few folks in regard to this issue.

  • Linux 3.12 and streaming media on a Dell XPS 13: kernel panic

    Hi all,
    Shortly after upgrading from Linux 3.11.6 to 3.12, I started getting kernel panics while playing streaming media (in particular from Youtube and The Daily Show). Here is a camera shot. The crash would not take place immediatly, but perhaps after 15 minutes of streaming. After downgrading to Linux 3.11.6 everything works fine. Therefore, it is clear to me that the issue is related to the Linux 3.12 kernel, but this is all I know.
    The fifth-to-last line from the camera shot reads:
    [11438.332699] RIP [<ffffffff8129e160>] __sg_page_iter_start+0x20/0x20
    A quick Google search reveals that __sg_page_iter_start is a function inside the scatterlist.h library in the Linux kernel, which apparently deals with memory paging, but my knowledge about this stuff is so poor that the message is almost meaningless. I would greatly appreciate if someone could give me a hint about this.
    I did not find anything useful in the journal, but here are the last few journal lines for 2 different crash instances:

    In the first journal log, the following line calls my attention:
    Nov 15 00:26:02 xps kernel: perf samples too long (2530 > 2500), lowering kernel.perf_event_max_sample_rate to 50100
    However, this seems to be a normal occurrence after playing games (https://bbs.archlinux.org/viewtopic.php?id=170471), so I would guess this is not related to the kernel panic.
    For reference, here are some hardware specifications of my Dell XPS 13:

    Posted to [email protected], I hope I just haven't dawdled for too long and this can make it to 3.13 final.
    Hopefully this should be sufficient information, I've linked to this thread too.  I've also mentioned I'm willing to beam one at someone from Amazon, with 2-day shipping to the USA the Pluggable branded adapter is just under NZD$40, which I can easily live with.
    ===========================================================================================================
    USB3 gigabit ethernet adapters with the ASIX AX88179 chipset (LevelOne USB0401-V3, Plugable USB3-E1000, SIIG JU-NE0211-S1 and others) are experiencing kernel panics in usb_hcd_map_urb_for_dma since 3.12.  The issue does not seem to directly correlate with low or high network activity, occurring seemingly at random.  Some panics occurred less than 5 minutes from boot and tens of megabytes of network transfer, while on other occasions it would be stable for multiple days with tens to hundreds of gigabytes of line-rate throughput and several sleep/resume cycles.
    Both my Sony Vaio Pro 13 and another user reporting this issue on the Arch forums [1] are Intel-based, my USB controller is an 8086:9c31 (Lynx Point LP), the other is reported as a C210/7 series (unknown PID).  A third with a Haswell Dell XPS has attempted my workaround and reports similar success.
    I have a mediocre quality photo of my laptop's screen from one of these panics [2], the call trace - which is similar but not identical between my machine and that of the other user reporting the issue - is as follows:
    usb_hcd_map_urb_for_dma
    usb_hcd_submit_urb
    local_bh_enable_ip
    selinux_parse_skb

    fget_light

    system_call_fastpath
    So far as I can tell, the driver is unaffected as late as 3.11.6, but problematic as of 3.12 (and still affected in 3.13-rc5).  The history of drivers/net/usb/ax88179_178a.c for this time period yields this patch, which at least in my somewhat limited understanding appeared a likely candidate.  I've reverted this on my system - against several linux-next builds from the last 3-4 weeks - and have had no issues with this network controller since.
    commit 3804fad45411b48233b48003e33a78f290d227c8
    Author: Ming Lei <[email protected]>

        USBNET: ax88179_178a: enable tso if usb host supports sg dma
        This patch enables 'can_dma_sg' flag for ax88179_178a device
        if the attached host controller supports building packet from
        discontinuous buffers(DMA SG is possible), so TSO can be enabled
        and skb fragment buffers can be passed to usb stack via urb->sg
        directly.
        With the patch, system CPU utilization decreased ~50% and throughput
        increased by ~10% when doing iperf client test on one ARM A15 dual
        core board.

    Unfortunately I have not retained the built kernel from a broken 3.12 build, so the system information below reflects the patched linux-next kernel I am running currently.
    I understand this may be a somewhat obscure piece of hardware, I am willing to assist by drop-shipping one to someone from Amazon (or local country equivalent if the price is not extortionate) should it be required.

  • Yoga 2 Pro Went DEAD After BIOS Update

    Had a horrible experience .. with good ending ... when upgrading Bios for my Yoga 2 Pro. So I'd like to share with others. I bought my Yoga 2 Pro last June (Man 3/22/14) and love it! But, it had problem restarting automatically after Windows Update. At least 3 times (That I can recall. Did not use it briefly from June 30 - July 22), the screen reminding user not to shutdown after Windows the update would stay on until I manually powered it down and restarted it. Last July 23, it did again after Windows Update. Searched Lenovo web-site and found a Bios Update for Yoga 2 Pro (Win 8.1 64-bit). Downloaded the new Bios (dated July 11, 2014) and went through the instruction striclty. First of, the screen responses were not at all as detailed in the instruction. So, the instruction is not very good.  Received 2 warnings: Make sure the laptop is connected to the charger during the procedure, and the bios is for Yoga 2 Pro ONLY do not install it on any other models. As part fo the procedure, the laptop switched to a Bios Utility program. Again received the aforementioned warnings. Update progress was shown on the screen. All of a sudden, then screen went blank and the keyboard stayed lit. Waited for about 30 minutes. Still the same. Press and held the power button down (not sure for how long)  ... nothing!   Just no response from the latop.  Called Tech support. She (the tech support lady) said that ... it is not recommended for user to go through the BIOS upgrade! What?  Then why post it on Lenovo.com? She also said that I should not have downloaded software from the internet and upgrade, especially for BIOS. Well, I told her that I did not download the program from ANY web-site, I downloaded it from LENOVO.com. She said further that looks like the BIOS update had damaged my mother-board, there is a problem with Win 8 & 8.1, and because it was my own doing ... the damage would not be covered by the warranty!  Considering the circumstance, Lenovo would waiver the initial $99 fee to assess the damage, but I would have to pay for any repair costs. In any case, I was so fumed at Lenove Tech Support responses that I hung up. close my laptop and put it aside. Almost 24 hours later, when the battery drained completely, I connected the laptop to the charger, press the power button to turn it on ... and ... to my surprise, the laptop booted and everything came back normal! The last (7/25) auto restart seemed to go well. Not sure if the auto restart problem is fixed with the new BIOS, but it seems to be. Time will tell.

    Thank you for your posting.  I searched the net when I ran into the problem, but could not find any help.  Obviously, my search was not exhaustive. I was trying to make the following:    a.  Lenov should be more specific in their BIOS update instruction.  Their instruction was ... far ... far from reality.      b.  Lenovo tech assistance was ... not much help.  After listening to the description of my prolem, the tech lady immediately said that the operation must have damaged the mother-board, and that the operation is not ... recommended.  No guidance on draining the battery a or how to restart the machine, etc...  What I received was confusing that caused more panic!   As a note, I had done BIOS upgrade on DELL PC/laptop before w/o any problem.  I fully understand the implication of a BIOS upgrade, but trusted that manufacturer fully tested whatever that they post in their web-site.  Oh well, live ... and learn!  All in all, the Yoga 2 Pro is a great machine and I love it!  Hope that anyone who runs into the same problem will be able to get the needed help in time! Cheers, 

  • Yoga 2 Pro returned. Worth to try again?

    I've had the 8GB Yoga 2 Pro for a about a month and a half and have had a lack luster experience with lots of issues of shutting down, freezing and just not being able to power on.  After trying to give it another try, I started it from scratch and it took 1 day for it to freeze again, shut down and then finally not be able to turn it back on again.
    So I took it back to Best Buy, thankfully I was able to fully return it with no issues.
    My problem is that when it wasn't causing me issues I really liked it, but is it worth it to try again?  Did I just get a bad apple?  Is anyone else out here having no issues at all?
    I need support, please!
    Moderator note: added some info to the subject line. Was:  Worth to try again?

    Constant freezing and shutting down are definitely not common issues, so if those are the only issues you've had with it and put up/did not notice anything else, by all means you should try again.
    I'm about to start pulling my hair out with mine because of all the common issues and the little things that for some might be unnoticable, but for me add up to a crappy experience. I think my experiment with Windows and 2-in-1s is coming to a close, but I can't be spending 1/2 time using the machine troubleshooting issues or worring about the stupid battery life because a Haswell machine can't last 6 hours if I use it for more than light browsing. Between XPS 12, SP2 and now Y2P, I'm pretty much done. Tomorrow I'm doing a clean reinstall, and will try it for a week. If nothing changes, it's going back, and I'm even looking at anything else in the Windows camp until all high DPI screens are the norm, battery life is trully 8-9 hours+, and MS has had time to iron out all the little crap. As much as I feel that in a lot of ways going back to Apple is a step back (I've really gotten used to a touch-screen for example), in my years of owning various Apple machines I have never once had any issues of this sort, and at the end of the day I need a machine that works with minimal fuss.

  • Need advice on graffics card upgrade for use of CS6 Mercury Playback in PR & AE w/ dell xps 9100

    I am curretly running CS6 on my dell xps 9100
    Windows 7 64bit
    12GB Ram
    2TB HD + 0 Rate 2TB External Drive (x2)
    Intel Core i7 930 operating at 2.8 gigahertz with an 8-megabyte cache.
      Memory and Storage  
    The Studio XPS 9100 can be equipped with up to 24 gigabytes of RAM. It uses Tri-Channel DDR3 SDRAM operating at 1333 megahertz. The computer has six DIMMs into which RAM can be plugged. The Studio XPS 9100 may have a hard disk size of up to 2000 gigabytes using SATA drives operating at 7200 rpm.
    Video
    ATI Radeon HD5870 with 1024 megabytes of RAM
      Expansion and Networking  
    The Studio XPS 9100 has one PCI slot, three PCIe x1 slots, one PCIe x8 slot and one PCIe X16 slot. It has four USB 2.0 ports, a 15-in-1 card reader, a headphone port and a microphone port on the front panel. The rear ports into an IEEE 1394a port, surround-sound audio ports, four USB 2.0 ports, one eSATA port, an S/PDIF port and HDMI ports. It has integrated 10/100/1000 Gigabit LAN through the RJ45 port on the back with optional internal Wireless-N. PCI card slot (PCI_1) 26
    PCI Express x1 card slot (PCIE1X3)
    PCI Express x16 card slot (PCIE16_1)
    PCI Express x1 card slot (PCIE1X2)
    PCI Express x1 card slot (PCIE1X1)
    PCI Express x8 card slot (PCIE8_2)
      Chassis and Power  
    The Studio XPS 9100 is 19.4 inches high by 7.8 inches wide by 20.7 inches deep. It weighs about 40 pounds. A 525-watt power supply powers the computer.
    I use Audition, Premiere Pro and After Effects (Dynamic Link) to edit concerts filmed on 4 HD Camera's (m2ts x3 and mp4) I also take and mix 6-8 tracks from soundboard and mix in audition. I find my system is struggling to keep up when I have done some color correction and then try to cut in multi-cam mode. My graphics card does not support CUDA and as stated above my system only has a 525w power supply. So a GeForce GTX 470, 570, 580 would not be compatable. I do not GAME but I work with large HD files (4 angles, 1-2 hours each, audio & effects).
    My trouble is I don't know which one of the graffics cards that support Mercury play back, would be the best for my needs without having to upgrade my power source (if possable). I'm thinking a mid level card and another 8-12 ram upgrade would be more suited (and cheaper) to my needs, unless I'm going to need a power upgrade anyway. If someone could please let me know what card would help me with my worload of these that would be great! I guess what Im saying is can someone tell me which of these is compatable with my system and is it worth it for the change in performance I will see?

    Right now I can get a 570 for 175 bucks... R4yMoNd. When I look at the 570 in comparison  to what I have it doesnt look as though itis going to make too much difference. http://www.hwcompare.com/9048/geforce-gtx-570-vs-radeon-hd-5870/ I'm sure however the CUDA cores will speed it right up. I'm no good when it comes to all that so thanks to both you for the help. I have tracked down a 670 in stock (seems tough) for $440 then I need a 700 w power supply for about 70. If the 570 should take care of the problems listed above thats what I'm going for.. Just wasnt sure if it would make the needed difference

  • **imac vs. Dell XPS 720 or new 630--Help!!

    Hi,
    I have been using windows and pc products for over 16 years. I am looking at getting the new imac 20" 2.4GHZ but, I am also looking at the Dell xps 720 and new 630. I am video editing quite a bit. I always use Vegas 8.0 Pro which is fantastic!(windows only) Now, I am aware of bootcamp and love that but, my concerns are a few things.
    1. The Dell xps 630 has a Nvidia 8800 GT video card vs the imacs ATI radeon hd 2600 pro. My question is will the 2600 hd keep up with higher end editing with an "imac 4gb configuration and 750 hard drive?"
    2. BootCamp question: I am aware that if I dedicate more than 32gb of space of the imac hard drive to windows, it will be ntfs and "not" writeable only readable. My question is, when I record some files onto the drive while using windows through bootcamp, can I record them direct to the "apple side" of the drive so I don't have to dedicate too much drive space to windows to begin with. I only want to use just a little of the drive to have my windows programs on it. So basically I'm saying, can I be working in windows and saving direct to apple side of the partition. And if I can, will that allow me access them using windows if they are saved on the mac part of the drive?
    3. Last question, if Dell xps has a far superior graphics card, why go with the imac? I really do LOVE that imac! I just want to know, with what my situation is, would it be wise to get the imac? Thank you all so much!!

    I was faced with the same choice just a few months ago, so let me give you my perspective.
    I have been a pc user for quite a number of years when it finally occurred to me that I was paying a premium price to help Microsoft debug the Windows os. The massive amount of bloatware that was included with EVERY manufacturer installed version of Windows started to get on my nerves. Plus the fact that daily virus updates were not an option, but a necessity.
    If you wanted "safe" browsing, your firewall would block most sites, but you were foolish to turn it off.
    Windows updates were just as bad. Your system would update willy-nilly without you having any idea what was being updated.
    In short, it got to be a pain in the * just to go online.
    With my iMac (20" 2.4 w/750gig hd) work is a pleasure. I have no fear of a virus attack on email or from any sites that I visit. Updates are a dream. I now check sortware updates once a week and there is usually nothing to update. My boot times are less than 20 seconds where on my pc it would usually take from 3 to 4 minutes.
    If you get your iMac DO NOT get your memory from Apple, unless you prefer to be ripped a new one. I got my memory (4 Gig Ram) from OWC for less than $100.00 total, but there are many others out there.
    hope this helps.

    From my personal experience, I wouldn't go for an Integrated card. This is one of the most important components for Photoshop, so invest in a decent graphics card (ATI or NVidia). It doesn't have to be a really exepensive one - I have been using ATI Radeon with 256MB of RAM on my Dell Studio for almost two years and it still rocks! (even when I work with 3D in Ps CS5 Extended).
    I would also invest in more RAM (this can be added easily - I bought extra 4GB as my Studio came with 3GB).
    I wouldn't worry about the processor - I'm on Intel Core 2 Duo - and it works very very well, it's very quick which is very important as I'm training Photoshop.
    I hope this helps.

Maybe you are looking for
