Usb 3.0 purchase question [solved]

Just thought I would ask the community a question before I make any hasty decisions. I have a Lenovo Y510 laptop ... it's coming up on 2 years old and is not as nearly as flash as it used to be, at least compared to the lappys my friends are now purchasing. I have no reason at all to buy a new laptop but I really want to be able to use USB 3.0. The only way I see this happening is with something like this: http://www.newegg.com/Product/Product.a … -_-Product
Of course they don't advertise linux support, but I was wondering what IS support for these types of devices like on linux?

There's a big catch-regardless of compatibility.
USB3.0 is designed for throughput of 5 Gigabit/second on each port. PC ExpressCard 1.x only supports 2.5 Gigabit/second. Even PC ExpressCard 2.0 (recently unveiled if memory serves), and a full PCi rail on an ATX mainboard only support a max of 5Gigabit/second, i.e. only ONE USB3 port at full bandwidth. You see the problem, no?
The lesson here is that USB3.0 as a PC card on a laptop is only worth the trouble if you have a PCExpress 2.0 slot, and even then it only gives you 1 full speed port and nothing more.
Of course, I can't think of ANY peripheral device that can even take advantage of 5 Gigabit/second (or 600+Megabyte/second) of throughput. No peripheral device to my knowledge out there can feed that much data through a bus at that speed today.

Treadmill Purchase Questions

I wasn't sure where this question should be posted (Health & Fitness or BB Policies), so I chose this one. I'm assuming it will be moved if I'm incorrect.
I'm considering purchasing the Proform Performance 1850 treadmill (PFTL20511), which I understand is a "special order". Unfortunately, I have a few questions about delivery, installation and warranty of such items. I've searched the website but so far haven't been able to find the specific answers I'm looking for. The questions I have are listed below. I'm hoping that someone on this board can answer one or more of them, or perhaps point me in the right direction for obtaining the answers. I apologize in advance for the length of this post, but considering that this would be nearly a $2K purchase, I'm simply trying to do my "homework" before taking the plunge.
* Regarding delivery and installation, the special order information says "Service includes product delivery and basic installation, but does not include specialty installation. See details on Delivery and Installation Services.". So my first question is, what does "basic installation" mean in terms of a treadmill? I understand that these things come on a pallet and can take hours to assemble. Clicking on the "details" link only provides detailed information on specific major appliances (Dryers, Stoves, etc...) but there is no information related to Fitness Equipment and/or Treadmills. In fact, the section that lists equipment requiring "special installation" doesn't mention any fitness equipment whatsoever.
* That leads me to my next two questions, Does Best Buy offer assembly services for Treadmills? If so, where can I go to find information about that service (cost, terms, etc...) ? Again, there is no mention of that on the BB website.
* From what I'm able to see, BB does not offer any additional protection plans for this item. Using the website, I went through the steps of placing an order for the treadmill, holding short of the final confirmation. On no screen was a protection plan ever offered, nor were there any links or pop-ups offering such a plan (as I have seen when ordering other productions from BB). So does this in fact imply that BB does not offer protection plans for treadmills, or have I missed something?
* Finally, what is Best Buy's return/replacment policy on fitness equipment that is faulty right "out of the box"? Here's a dreaded scenario. The unit is delivered, removed from the pallet and unboxed. After hours of assembly it is determined that some part is defective or has somehow been damaged (perhaps during transit). Chances are by that point re-boxing it and getting it back on a pallet is not an option. Can a customer still get the defective unit replaced or perhaps even return it for a credit?
Thanks.

I know this is waaaay down the road but since nobody answered, for special delivery items they are simply dropped off. That is all. I haven't seen protection plans available on large exercise equipment but I have assumed it isn't offered. Yes returns are possible. It would have to somehow be made shipable or you would have to return it to a local store which doesn't sound like much fun either.

Weird because I marked that my user name had solved the issue. But no points... Probably to prevent users from generating their own points. Oh well.
Thanks for helping me with the original posts babowa. Frustrating to get it fixed only to screw it up again. What happened was I was looking at your post, I clicked on the link to check and see that my original post had indeed been relocated, and then I was distracted by something. When I got back to what I was doing, I wanted give you the solve credit, but didn't bother to look closely at which post was displaying.

Sony Vaio VGN-N27LH - some questions SOLVED

SOLVED - I installed the sony_acpi module from AUR and run the following to dim:
echo "4" > /proc/acpi/sony/brightness
Would still be grateful if anyone could advise on what else I need to consider when running linux on a laptop. My original questions/post is below.
So I took the plunge and bought my first latop.
However, running linux is significantly more difficult and I'm feeling somewhat swamped. On my desktop I just installed Arch and it ran fine. With the laptop there are issues of power management, speed-stepping,suspend to disk, ACPI, etc, which are all new terms for me. As I say, on the desktop I just installed Arch and it ran fine. Nothing else to worry about.
Let's start at the beginning. I installed the beta version as I couldn't get an internet connection with my older version. Having done some reading I've installed a few things and added some daemons but am still struggling to lower the brightness of the laptop.
Below are some details:

I'll be honest, I've no idea what half of those modules and daemons do! I just know they are installed and load fine - there are no errors when the system boots. What's more, I haven't edited any configuration files so whether those daemons are actually doing anything is anyones guess.
So, any ideas on how to get the brightness down? Equally, are there issues that I need to be aware of when running linux on a laptop. It seems to be running quite hot and I dont know whether this is normal or not?
Please don't shoot the noob. Help greatfully received. Be gentle.
Thanks.

wiki has some info, one of the Vaio pages is written by
although its quite outdated it might give some hints (laptop-mode-tools for example) and inspire you to writte a new wikipage
they say kernel 2.6.21 has the vaio brightness control inside him, so I'm waiting for 2.6.22 to see how things work with Vaios
laptops aren't more difficult than desktops, Vaios are pain in the butt (its the first and the last I'll ever buy )

New ipod and computer purchase questions

A. Do people have less problems with their ipods with Apple computers or window computers?
B. Does the 5G 30gb ipod support firewire and if so, do I have to purchase a firewire?
C.I was thinking of upgrading my daughters computer to USB 2.0 but heard horror stories of the 2.0's being incompatable and not working..

A. This is a difficult question to answer but based
on the number of posts here only, I believe overall
people have less problems with an iPod and iTunes
using a Mac than a PC running Windows.
B. Yes and No. It supports Firewire for charging
purposes only but to transfer data requires USB which
doesn't make most Mac users very happy. Switching
from Firewire to a USB requirement was to allow more
support for PCs, not Macs.
C. Purchase a new Mac which will have USB 2.0 ports
in addition to a Firewire port or ports and no
concerns about viruses, adware or spyware.

USB Fatal1ty (ef0210) general questions

Just a couple of (most likely) noob questions here. First off, the USB Fatal1ty gaming headset (ef0210)... Does this headset give true 5.1 channel sound or just "simulated surround?" I mean does it have four speakers in each headphone cup like the analog version of the Fatal1ty? Or am I going to get "surround" out of a pair of stereo speakers?
Now, time for opinions.
Secondly, if it is true surround, 4 speakers per cup and all, which would you suggest? Would you suggest the USB Fatal1ty (same model as mentioned above), or the analog version with the multiple jacks, and the X-Fi USB 5.1 surround card.
I found that the virtual surround just doesn't cut it anymore with my games. If you have any other suggestions for a true 5.1 setup through USB means (I am using a laptop and have no PCMCIA, so a "real" soundcard isn't an option) that is close to the prices of either of these sets, please let me know as well. Thanks in advance.

1. Address Book > Menu > Filters. UNcheck all filters.
Do you see any of your contacts now?
2.You can disable the clock from the Options > Clock settings.
3. Correct, always eight characters with a combo of numbers/letters or a rare occassion of all numbers
4. a. On your homescreen, press the Menu key > SHOW ALL, so that SHOW ALL is checked.
b. Look in EACH folder on your device... Applications, Instant Messengers, Downloads, etc.
If you still don't see it, look at Options > Advanced > Applications. Do you see it listed there?
5. Try plugging the USB cable to a REAR usb port, not a USB hub or port.
Reboot your computer.

USB 3.0 dock question

I have a Thinkpad Edge E530 and recently purchased the Thinkpad USB 3.0 Dock. My question is how do I set this up so I can close the lid of the laptop and continue to work?
I have a USB keyboard, USB mouse, Network cable, the E530 laptop and monitor connected to the Dock. I want to be able to close the lid on the laptop and work with the keyboard, mouse and monitor.
Is this possible? Do I just need to change the sleep settings on the laptop?
Thank you.

S10-3T purchasing questions

Hi all,
I've been following the S10-3T news for a while and I can't wait to get my hands on it, however i have a few questions before doing so.
I have never purchased a netbook before, i understand that there are no CD drives. How does this complicate things in terms of say me needing to format the netbook? I know that I can download the windows 7 upgrades from the microsoft site. What about programs I already own with a CD?
and is it advisiable to first format the tablet, and then install the things I need?
Thanks.

Hi and welcome, first to have an external USB opticaldrive (slimline-dvd-burner)...is not a bad idea...it helps you to do some things easier...to have a good backup in your hands in case of emergency, first Backup your system, before you think of format your computer, in addition a usb-harddrive to save your personal data from time to time......than you can install all .. your fav operating system and programs....

Syncing iPad & iPod... device USB port cable connector question

I have an iPad & iPod 4th gen.... both syncing cables look identical..no identity markings on either. I'm not sure now which came with which device.
QUESTION: Are the syncing/charging ( know I can't charge iPad off USB port) cables given with purchase interchangable for these 2 devices?
Thanks!

Yes, the cables work the same. It is an Apple proprietary 30 pin connector.
The chargers are different. The iPhone/iPod charger is 5 watt. The iPad charger is 10 watt. But you can use the iPad charger with iPhones/iPods because it is self limiting.

IMac 27" pre-purchase questions

Good Afternoon,
I am really close to ordering myself one of the new 27" iMacs but am struggling with the customisation options (who doesn't!)
This will be my first ever Apple Mac computer and I have tried to find answers to my questions elsewhere without much success.
For background info, I am not (and never will be) a professional photographer, videographer or music producer - I just want an iMac that will allow me to do all three tasks amazingly smoothly and maybe the odd bit of gaming - either using MAC software or PC software via Bootcamp or Parrallels 8.
So onto my first question - I already own an ICYDock MB559U3S-1SB Slim USB 3.0 & eSATA External HDD Enclosure and using a MB882SP-1S-1B 2.5" to 3.5" SATA SSD / Hard Drive Converter - I've fitted it with a Crucial 256Gb M4 SSD - leaving me feeling the cost of the 1TB Fusion Drive @ £200 may be unnecessary.
Will I be able to boot the new iMac from my external SSD?
If yes, what's the best way to connect it to the iMac - via USB3.0 cable or eSATA using something like the Lacie eSATA Hub http://www.lacie.com/us/products/product.htm?id=10574)
Assuming the iMac was booted from the ICYDock + SSD - would it be possible to (hot) unplug the 'boot' enclosure and insert a 'data' HDD enclosure without causing any problems whilst the iMac is on?
Would Bootcamp work from the ICYDock + SSD?
I have recently sold my Core i5 Windows PC to help fund the purchase of the iMac and to be fair, this Intel CPU handled everything I wanted to do on my PC with ease. It was fitted with 12Gb Corsair 1600MHz ram and an nVidia 660Ti 1596Mb PCI-e x16 graphics card. I'm therefore debating whether the i7 upgrade is actually going to provide me with a noticeable (+£160) performance boost. I will definitely be upgrading the memory to 32Gb myself and opting for the 680MX with 2GB DDR5 upgrade option.
2. Would you recommend I go for the i7 upgrade or will the i5 turbo boosted to 3.6Ghz suffice?
I'm still not sure if Bootcamp/Parrallels gets to use 100% or 50% of system resources or whether it's a user configurable option within Mountain Lion?
Does Hyper-Threading help when using plugins in Logic Pro?
Lastly, when it comes to upgrading the memory in the new iMac 27" - can anyone confirm if this Corsair memory fits comfortably / works well?

Many thanks for your time and insight

I'll be mostly using it as my main computer for everyday tasks along with learning Logic Pro.
My son is currently studying Film and Photography at College so he will use it infrequently for catching up on his course work - he mostly uses Final Cut and Adobe Suite.
One other thing I forgot to mention is connectivity to an existing 5.1 speaker system - If I buy a Mini Jack (Toslink) to Optical Cable and plug it into the headphone jack on the rear - will it automatically output to 5 channels or will I just get 2 x Stereo output?
Apologies if these are simple questions its just I don't have access to or know anyone who owns a Mac.
I'll be looking to join a MUG nearby once I have my new machine - but not before as it would frustrate me more if I could not come home and try out some of the tips I hope to pick up

Computrace purchase question

My X301 was stolen in August. I was so sad about it. Now, I just received a lovely T400s. To avoid the same to happen again, I seriously consider purchasing a Computrace service to track and recover it.
On lenovo.com, I found "ComputraceProfessional 3-Yr" Part number: 41U4786 for $90 under accessories / services. However, clicking on details gives me nearly no information. Then I went to absolute.com, the provider of computrace services, and just to find there is no service called "Computrace Professional". What they currently offer are Computrace Complete / Plus / Data Protection / Absolute Track / Mobile / for Netbooks.
Does any on here know what exactly is "ComputraceProfessional 3-Yr"?

USB Charge and Play question

I recently needed to free up a different USB port on my Satellite A665-S6086 and had to plug my cooling fan into the USB port that has the "Charge and Play" (Play and Charge? I can't remember the exact name) feature. Now, when I turn off my laptop, the fan continues to run because I have that feature turned on. My question is, how do I turn it off?
Thank you.
Solved!

Have found out exactly where u need to go in the bios:
When in the bios,
Use the arrow keys to navigate to the “Advanced” Tab.
Again using the arrow keys scroll down to “USB Sleep and Charge”.
Press the “enter” key to change the settings to either “mode 1” or “mode 2” (Im assuming disable will be here too).
Press the “F10” key to Save and Exit the Bios configuration and select “Yes” to “save the configuration changes and exit now”.
The computer will now reboot.
Hopefully that info is correct,

Yoga 2 13 (Not Pro) Pre-Purchase Questions

Yesterday I looked at the Yoga 2 13 Ultrabook (non-pro version), 4 GB RAM, I5 processor, 500 GB hard drive at a big box store. I am seriously considering this, but wonder about fan noise (under high load conditions) and any other possible issues that this computer may have. I am sensitive to fan noise, because I work, watch or listen in quiet conditions. I asked the salesperson if they have a quiet place that I could take the computer and the answer was "NO".
Does anyone have experience with this (or similar Yoga 2) computer and could comment on the fan noise/sound and any other issues that you have noticed, i.e. Wifi performance or simultaneous use of Wifi and Bluetooth?
Thank you in advance!

Hey! thanks for the response. my biggest concern is:
1.) Battery life in different scenarios. For my current laptop when I take notes for class I usually turn off all wireless devices, dim the screen to the lowest, and switch on power saver. I also turn off processes that aren't being used. Can you comment on the battery life and how long it lasts to your knowledge in different scenarios?
I found this thread on the yoga 2 pro battery life (which i'm sure you'll be able to relate with regarding tips to increase battery life for your yoga
https://forums.lenovo.com/t5/Idea-Windows-based-Tablets-and/Yoga-2-Pro-Battery-Life/td-p/1272881/pag...
and I'm wondering what kind of battery life increases you could achieve by turning off Lenovo's Smart Voice, Transitions, Picks, Motion Control, etc...
2.) i noticed that there are some concerns with the yoga 2 pro regarding wifi disconnection issues. have you experienced anything liek this?
3.) which hard drive did you end up choosing? I'm personally learning towards the hybrid hard drive but i'm worried that it will "lock up" everytime I move the laptop. of course i wouldn't be making sudden jerks or motions, but because it is a convertible, i'm wondering if switching between modes (tent, laptop, tablet) would trigger the hybrid HDD to lock up as a cautionary mechanism.
I checked out the laptop at best buy and i really really like it better than the yoga 2 pro, mostly because I like the smooth surface of the keyboard so much better than the rubbery texture. is there anything else you can comment on the laptop that you wish you could change / you knew before you bought it?
Wow that was a lot of questions. thanks for your help!

USB External Hard Drive Question for the E4200 v1 router

I know this is going to be a really dumb question, especially coming from a computer tech of 25 years, but I'm going to ask it just to be safe.
First off, my router is the E4200 v1. It's a substitute for my older WRT54GS router. One of the features I am quite fascinated with is the USB external drive usage. Here's my question. I have a Western Digital My Passport Essentials 500 GB external drive (Model #WDBAAA5000ABB-02) that I want to use on it. I know it's not on the Official List of tested USB storage devices for the Linksys E4200 but I really want to use it, especially for storage on my three computer systems. My question is do I need to unplug the router power supply BEFORE I plug in the external drive to the USB port on the back, or does it matter?
Any help is appreciated. Again, I know it's a dumb question, but the guides and "How-To" on the Linksys website isn't exactly clear. Thanks in advance!
