Choosing notebook with Sandy Brigde processor and discrete GPU

Hi!
I'm looking for new notebook. I have 2 candidates, both are Sandy Bridge so I am afraid that Arch will have problem with GPU.
My first candidate is Lenovo IdeaPad y570. Specification is:
i7 2630QM processo
HM65 Express Chipset
nVidia GeForce GT 555 discrete GPU with optimus
Lenovo has a button to switch off and on discrete GPU.
My second candidate is HP ProBook 6560b with following spec:
i5 2520M processor
HM65 Express Chipset
AMD Mobility Radeon™ HD 6470
I don't know if it is possible to switch off discrete GPU in BIOS
What should I expect from these laps? Which one is more likely to work with less problems?
I do not need discrete GPU since I won't play games. I just need fast and stable laptop for heavy development and long lasting battery. But flickering, low resolution or any other problem with X.org should not happen.
Thanks!

I know this is not one of your candidate, but with the price range of both of your candidate, you should choose
either thinkpad X220 or T420, 12inch and 14inch respectively. Since only thinkpad support the tp_smapi package
which provide the battery_threshold feature that lets you stop the battery from charging, which result in longer
lifetime of your battery.
You can also install TLP which provide more battery saving feature, And most of all it just works.
Try to refrain from buying the Edge series, at least in my experience the LCD is botched after 1year+
of usage, maybe it is one of those 1 in a million thing, but it is hard not to mention the fact.
Then again it's your choice.

Can I transfer docs between a MacBook with a Intel processor and a iMac with a PowerPC processor by using a usb cord?

Can I transfer docs/folders between a MacBook with a Intel processor and a iMAC with a PowerPC processor using a usb cord? Or by loading from the MacBook to a external drive and then to the Imac.

You need to use an external drive, FireWire cable, Ethernet cable, or wireless connection.

Thanks for the reply,. I went to the site provided and executed the directions but this did not solve the issue.
Even more details:
If I send a message to the Jane Doe address from another account on this machine (all my family uses the same email services provider and each have accounts set up on this machine), when you open it, it shows Jane Doe then the <applejax.xx> address AND the picture associated with the Apple Jax account.
So the problem shows up when the message is sent to this account from this machine, AND when it is sent from this machine from this account. No other accounts on the machine are effected.
I have sent and received email messages from the mail service provider's website, and everything is fine.

What happened to X201 with i7-620M processor and X201s?

Been looking at the X201 with the i7-620M processor and the X201s.
Looking at lenovo's website today, seems like the X201 now only comes with the i5-540M processor and the X201s is no where to be found?
What's going on? Are these discontinued? Out of Stock? Or did Lenovo take them off the website while they revise the specs? I'm hoping they just took them off to upgrade the specs. If they come out with a X2xx with WXGA+(or better) screen and i7-620M processor(or better) I would definitely pick one up.

Chooser problem with HP PSC 1410 and HP Deskjet 5940 on Classic

Excuse me for my bad english, I am french... !!!
I have just bought macmini with HP DeskJet 5940 promotion. I installed internet last driver for it. Printing is OK with Mac OS 10.4.4 but doesn't work with Classic. Printer is connected by USB port. I tried with another HP printer : HP PSC 1410. It doesn't work too under Classic.
When I try to print under Classic from SimpleText, I obtain the message : "SimpleText ne peut imprimer un autre document pour le moment. Utilisez le sélecteur pour choisir une imprimante". I translate in english : "SimpleText can't print another document for this time. Use chooser to select a printer."
I open chooser and click on LaserWriter8 as indicated in documentation. I obtain a new message : "LaserWriter8 requiert AppleTalk. Assurez-vous que vous êtes bien connecté au réseau AppleTalk." I translate in english : "LaserWriter8 asks AppleTalk. Be sure that you are connected to AppleTalk net.". I click on OK and two new message appears : "Impossible d'ouvrir AppleTalk". I translate in englisk : "Can't open AppleTalk" and "Pour activer AppleTalk, ouvrez les préférences Réseau et cliquez sur AppleTalk". I translate : "To activate AppleTalk, open net preferences and click on AppleTalk". Evidently, that is already made !
But it is absolutely necessary that I can use deskjet printers under Classic with my macmini which runs on Mac OS 10.4.4 !
I turn around the problem and I don't find solution. Have you some ideas ?
Thank you for your help !

Pardon: je parlais Francais comme une vache espagnol et unless HP specifically says so, there is no guarantee that any modern printer will work in Classic - partly because printer manufacturers don't bother with aging software, and partly because some printer manufacturers seem not to understand that Classic over OS X deals with printers very differently from the way pure, bottable OS 9 does.
If you have a freshly installed OS X with a freshly installed Classic 9 and the right versions of HP's drivers and utilities, it should work - but if any of those is not freshly installed, there might be third-party components interfering.
If all-fresh software doesn't work, launch Apple's own Desktop Printer Utility and tell it to create a virtual Desktop Printer with Translator Postscript.
Even though it doesn't actually appear on the Desktop, that will become the default printer for Classic, accessible thorugh Chooer's LaserWriter driver.
Try again to print from SimpleText but set the dialog to Print to File, which should create a .ps file that can be dragged onto any X print queue, where it should just print! (To find an X print queue, Print from any X application and tell the Dock to Keep the icon)
That method is not guaranteed, but it does work for most people with most printers.

How do I play dvds on hp envy touchsmart 15 notebook with an external player and Windows 8.1.

I have a HP Envy Touchsmart 15 NOtebook PC. I bought an external HP DVD player model dvd600s-H01 5 but I cannot play DVDs.

Hi @pattyathome
Welcome to the HP Support Forums!
I understand that you are having trouble with an external dvd player attached to your notebook.
What is the full product number for your notebook? Please read the following if you need help in finding that.
How Do I Find My Model Number or Product Number?
Does your notebook already have a built in dvd drive?
Did you install the drivers and software that came with the external dvd player? If there was originally no DVD player in your notebook, it is likely that there is no dvd player application loaded.
So in that event I would recommend installing from the software disk with the DVD drive.

Graphics Card For HP 630 Notebook With core i3 Processor .

Hello, I have bought a HP 630 about a week ago. I was wondering if there is way Intel HM65 Express can accommodate a graphics card and also wanted to check if can get a solid state hard drive on this lapotp if it is possible. Viswanath

Hi: Below is the maintenance and service guide for your notebook: http://h10032.www1.hp.com/ctg/Manual/c02834036.pdf Please see chapter 4, page 49 for the memory removal and replacement procedures. The picture isn't very clear, but you have two memory slots with one chip stacked on top of the other. If you install memory greater than 4 GB, then you will need a 64 bit operating system.

HP notebook with windows 8.1 and HP usb Displaylink HSTNN SO2 not working

I have just purchased a new Pavilion Laptop with Windows 8.1 this is replacing my old HP laptop that ran XP.With the old laptop I ran a second screen, keyboard, track ball type mouse and a HP 6300 printer via a HP / Displaylink USB docking station. I now find that the keyboard, mouse and printer all work OK (I have not set up the second screen yet so I am not sure if it works) but every time I print. I get a screen pop up telling me that I need to go to Displaylink.com/software and download the correct up date! When I go to the site I get a long list of updates but also a warning telling me to contact HP to make sure you have the correct download! Help I am going round in circle's. Has anyone had this before and if so what is the correct download to us? Thanks Robo 64

HT203177 I have a 2TB Imac, 10.7.2, with 2.8 processor and Intel Core i7, with 16 Gb of memory, and 1067 MHz DDR3. I have tried to backup to a WD 4TB. It ran for almost 7 hours, and then the little box came up saying it had 5 seconds, but would not stop.

I have tried backing up my iMac using Time Machine. I have 727 GB on the 2 TB internal hard drive. I am trying to back up to a 4TB WD extrnal hard drive. Everything seems to work fine, even though it took almost 7hours to go through the process, then the little progress box should it had 5 seconds left, but it kept running and running for another 4 hours, until i finally shut it down.
The WD hard drive shows that it has used 1.61 TB on the disk, but I cannot find anything in Time Capsule. I open the hard drive to see what is on it, and it just shows that it is in progress.
I'm lost and looking for suggestions.

How to use Real time execution trace toolkit with Dual-core processor??

hi there
the situation as follows:
i have a computer (PC and Laptop) types with Dual-core processors, and am trying to do simulation using Multi-core technology and based on different simulation scenarios...starting from sequantial processing,.......Piple lining processing strategy. so that i can differentiate the time delay between those types of processing based on (Using 1 processor then dual-core processor Computers)
my question is: As i read through Ni's white papers i saw many notes refer to Real-time execution trace toolkit to investigate the (processing-time , etc) of multi-core processors in processing diffenent algorithms. My algorithms are to be run on 1 computer with dual-core processor BUT, not in real time environments, that is ( No hardware to be connected to my pc) only algorithms running on my pc....
So, is it possible to use Real time execution trace toolkit or anyother tools in LabVIEW to show processing-delays and/or anyother timing critical issues without using my application for real- time hardware.???
in other words: how to use Real time execution trace toolkit in non-hardware and/or real-time scenarios???
please help me in this.
Any suggestion, comments, feedback.....is absolutely highly appreciated
thanks a lot in advance
Labview Lover

Hey,
The Realtime Execution Trace Toolkit only works for NI RT Targets.
But you can use the Desktop Execution Trace Toolkit, just search for it under ni.com.

Problem with Viewsonic VX2025 display and PowerPC G5

I recently switched from an old G4 tower to a less-old G5 tower with dual 2GHz processor and a GeForce 6600LE graphics card. The monitor I was using with the G4 is a Viewsonic VX2025, and they worked flawlessly together. Not so much for the G5. The monitor, which is connected via one of the two DVI ports on the G5, works when the computer is started cold. However, after a period of inactivity or sleep, the monitor goes black and will not receive a signal. The power to the monitor remains on, but the light on the monitor is yellow. If I tap the keyboard or click the mouse I can hear the tower powering up, and my mouse will flash its light, but the monitor will remain black. At this point I will have to power down via the power button. Occasionally, however, the G5 will not power down and I'll have to disconnect the power source. At this point turning the computer back on will result in the same black monitor screen unless I wait at least 20 minutes to turn it back on. In which case, everything will work fine as long as it doesn't go to sleep.
I've tried re-seating the power cord for the monitor, and checking the connections.
Now, I've switched to an old VGA monitor that I dug up from the garage with a DVI adaptor. This system works fine and I've had no problems. However, the monitor quality isn't very good and I need to figure out a way to get the G5 working with my Viewsonic. Any suggestions?

I have a Power MacG5 behaving exactly the same way with a large Westinghouse (LCM.22W) LCD Monitor. The problems began when I decided to enable the sleep function to save electricity. For years it worked fine and the sleep problems into an unwakable black screen started on and off with me doing the same to remedy it: restarting or unplugging and replugging the DVI 400 cable (Monster Digital Video)from the CPU DVI port. Now nothing works as a remedy. I have no alternate monitor to use to access the CPU. Now when I reseat the DVI cable the monitor says check connections indicating it isn't hooked up to a DVI output video source even though it is.
I'm starting to wonder if the problem is the G5 video card in the CPU and not the cable or the monitor since I'm not the only one who has experienced the problem with a large monitor when the computer goes to sleep and the monitor shuts down.

Can the new MacBook Air 13" with the i3 processor run Adobe Connect?

I need a new computer for college this fall. I really am leaning towards the MacBook Air, 13" model with the i3 Processor and an upgrade to 8 GB ram. Will this (w/ a 1.3GHz Processor) run Adobe Connect? It says it requires 1.83GHz for Mac. So is it not fast enough? Should I just get the pro? :/
Here is the site on Adobe...

Any help is appreciated. :)

I agree that the Retina display is only truly useful for photographers, etc; but as someone who owns a 13 inch Retina MBP and had a 13 inch MBA, I wouldn't necessarily clssify the non-Retina machines as "better". The difference in display quality is quite noticeable, I like it, and I've never had a problem running non-optimized websites or apps on the machine and I'm fussy about displays. Maybe that's because I've left it running at default settings.
It really all depends on where you want to put your bucks. In general, you can get slightly better performance for the same money with a non-Retina machine.
That said, if you're looking at benchmarks and using Geekbench, a 1.3 i5 2013 MBA comes out at 5940-5950; my 2012 2.5 i5 Retina benches out at 6777, so it's slightly faster but not remarkably so. The 2013 1.7 i7 MBA will match up with it and even exceed it a bit, at least until the Retinas are upgraded with Haswell later. I suspect they'll be faster, though it depends on what chips Apple uses and how much battery life they want to trade off for it. Also, you are using some graphics power with the Retina just to process the display, and the newer Intel graphics GPU's are generally stronger than the 4000 series in the current Retina, so that's a littl bit of the trade off you'd make.
The newer models have a faster disk access system and 8011.ac wireless though the latter is problematic at the moment and it will take some time for Apple to fix that. You'll also not be able to take too much advantage of the faster wirelss speeds immediately unless you buy a new (8011.ac) router; it will take a few years before the rest of the world catches up to the new standard. The 13 Retina MBP has an extra Thunderbolt port..which I routinely use..and an HDMI slot not present on the MBA.
Just do your homework, consider all your needs, and get what serves you best.

Defective Tecra S11 - Need new notebook with Express-Card-Slot

My TECRA-S11-166 is faulty.
I need a new Notebook with *Express-Card-Slot* and (if its possible) RS232.
What kind of Notebook comes with a Express-Card-Slot ?

Hi
There are different Toshiba notebooks on the market and Toshiba releases new models in very short intervals.
I would recommend you to visit the Toshiba notebook product page and to compare the available series and models.
The Tecra laptops offer a business professional use and Portege series are very best in mobile computing.
The Satellite series are entertainment machines designed to provide exceptional all-round performance.
