The device usually has to have a "B" USB port on it making it a node (rather than a hub, which provides power). I have not seen a Win 8 device designed to be a node. It is always the root hub and so seems to always be equipped with the "A" port. I don't think the USB specs allow the consumption of power via an "A" port. So the short answer, I believe, is no.
Wow... that is actually pretty cool. I think the battery in the keyboard is a pretty novel idea. I've got to hand it to Lenovo... that are really innovating in this area. I got one of the Intel Ultrabooks in the App Innovation contest and without fail, everyone I showed it to asked me if it was "the one that the display flips around on"? Which is, of course, the Lenovo (I had to begrudgingly admit).
I noticed the reviewer seemed down on the idea that it charged through the USB port. I can understand why... the current limit is pretty low so I imagine the the charge/discharge ratio is in negative territory (so it takes more than an hour to get an hour of runtime). I've noticed that on my Nexus 7 tablet if I plug it into a "standard" USB port... it will take 10 to 12 hours to fully charge. It needs a high-current USB port or, better yet, the high-current charger it came with. I bet that the Win 8 tab would see the same behavior.
So, I'm doing my first PC build in about 10 years, and I've never installed an after-market heatsink (the kind with the big tower, etc.). I got the tower mounted to the mb and processor fine, but for the life of me, I can't figure out how to attach the fan to the tower. The fan has two arrows at the top that are at right angles, and the fan is supposed to be mounted by two (or four?) high-tension wire clips that slip into the fins on the tower. The instructions are absurdly awful with no clear diagrams. I can't even tell which way the fan is supposed to point, much less how to mount it.
It's a ThermalRight True Spirit 140 ([^]); any tips on installing?
Well the picture in your link shows the fan held on by a couple of wire clips. If they didn't ship, I don't know what you can do. You might be able to just tie it down with a bit of hard foam or something to cushion it. Millimetre-perfect location is not important. You should be able to figure which way round from the curve of the blades in the pic.
wrt the arrows: One shows which way the blades move, the other shows which way the air moves.

Thanks; I was able to figure it out from the pictures the next day. Those clips were included but were an absolute beast to install. I'm not sure why they think they have to be that tight, but that easily took up half of my total hardware installation time.
Way back when I worked in speech recognition Andrea noie cancelling mics were the best. Make sure to have the mic off to the side of your mouth, you dont need to shout directly into it, and if you arent breathing all over it it will understand you better.
I had a problem with my laptop, when i started it, it showed a blue screen and then could not start normally except through safe mode. It is slow and has lost volume. What could be the problem and how do i solve it?
There's a chance the hardware in your computer is bad, in other words, the devices and circuitry inside your computer is probably fried or suffered water damage to the point it's causing serious issues for your system. How long has you since not used it? Did anything happen to it in the past that you may think is causing it a problem now?
What I would do is get a hard drive enclosure for a internal hard drive for a laptop and take all your documents off it and copy it to an external hard drive and then re-image your PC (reinstall Windows) with the internal hard drive in it (after putting your documents in a safe place).
Simple Thanks and Regards,

Programming in C and C++ now, now developing applications, services and drivers (and maybe some kernel modules...psst kernel-mode drivers...psst).
Many of life's failures are people who did not realize how close they were to success when they gave up. - Thomas Edison
In safe mode look at your system recovery settings and set it to create a full kernel dump when it crashes.
Then go to \system\ and look for memory.dmp
Copy it to another machine and install Windbg and open the dmp file.
Look in the Help and set the symbol path to Microsofts public symbols (search for symsrv in Help) then do an analyze -v and see what it says.
Then google the resultant error message, you could have a dodgy driver, there are plenty about, or it could be bad memory.
If you think you have found a bad driver restart the machine and run Verifier.exe at a command prompt and then set it to specifically check that driver, selecting most of the test options except 'low resource simulation' and the 'force delayed IO' or whatever it is called, reboot into normal mode, and see what happens.
If it blue screens again you *should* get a Verifier BSOD (blue screen of death) that will tell you more about the particular error. Then you can get an updated driver off the net or bitch to the company that made that crappy driver and get them to write you a new one.
32-bit versions of Windows are able to use up to 4 gigs of RAM. However, at times they might report a smaller amount as usable. Try flashing your BIOS to the latest version. That fixes most of memory issues. Go to the manufacturer's website for the latest BIOS drivers.
Also from the screenshot, your computer has a 64-bit CPU. Try getting a 64-bit version of Windows.
the simple solution use the 64-bit version of windows.
the other solution is that , you use a VGA " graphic card " that used a shared memory and he is taking from your ram , and to solve this go to your "Bios" and search for " Onboard VGA " or what equals it , then set your amount of ram that the VGA can use as a memory .
I am trying to change the tab stops on the printer before I send formatted text (w/Tabs) to it. I can change the tab stops in stringFormat and use it when calling DrawString but they are completely ignored, e.g.,
