You should be able to fix this rather easily. Your new 7260 is waking up your computer right after it goes to sleep for some reason. what you will need to do is find the 7260 in device manager, go to Properties> Power management, and deselect "Allow this device to wake this computer". This should fix your problem.

I may have uncovered a bug... I installed my shiny new 7260 (it's been awesome so far!) but now my computer won't sleep with either closing the lid or hitting the sleep button. When I hit the sleep button, it looks like it goes to sleep for like half a second (keyboard back light goes off and the power button blinks once) but it immediately turns back on after that.

I would love an answer to this too. Games are almost unplayable with the power unplugged. I don't remember where I saw this but I read somewhere that when it's unplugged it still uses the 750m, but super under clocked and you'd be better off using the hd 4600. Either way, I'd love to have manual control over it

If you're going to be upgrading, you might as well invest in some AC stuff because better performance and it's already out and just a matter of time before N becomes obsolete

It really depends on what you are doing... gaming, I would go for lower latency. Something like video editing, go for higher capacity. In all honesty, I think 8gb is more than enough

I actually really like windows 8. Once you get used to all of the shortcuts and what not, it's pretty decent. That being said, I boot straight into the regular desktop

I would def send it in if it's covered

Are there any external graphics card solutions?

Thanks liteon6x!

@theagent Yes there are a few programs that you simply can't get for PC. For example, I work in theatre and I have yet to find a better cue playback/show control program than Qlab, which is a Mac-only program

That's strange... Just out of curiosity what what device is dropping out? Could it be the other end of the cable?
