I bought this laptop
about 8 months ago. It's still under warranty, but I'd like to have an accurate answer of what is wrong.
Occasional I had a problem where window minimization with Aero would be really, but after a reboot it would be fine. That was until one day a reboot didn't solve the problem. Games would run slow. The FPS would be fine, but all the timing determined by the CPU would be really slow. Music playback was also be fine, but if a song would loop in a game since the timer (or whatever) is slow the loop would have a gap of silence after repeating the audio playback. After a reformat this lag still happened, as well as loading the system menus and BIOS screens taking about 1-2 seconds every frame render. This stopped for a couple weeks after putting it into my bag and heading off to class, but recently after putting my laptop in my bag again it has started again.
Everything appears to check out fine according to speccy.http://i.imgur.com/C9NMZ.png
Occasionally my GPU will have severe artifacts all over the screen. It has no correlation to the GPU's temperature, but often happens when I watching movies, and playing certain games. Also the performance is simply not as good. When I first got this I was able to run Starcraft 2 at around 40fps with medium-high settings at 1080p. Now I can only get a decent FPS at around 720p with medium settings.
I have a cooling pad for my laptop. Without it on a flat table the CPU will idle at around 70-75C and playing a games it can get well over 90C (until it shut off). The was originally no problem with the cooling, but the heating problem happened before any GPU or CPU problems, and after about 2-3 over heats I bought a cooling pad.
My laptop also came with a touchscreen. It has essentially worked very poorly ever since I got it. It was perfectly receptive when it worked, but it often disconnects spontaneously and sometimes repeatedly. Occasionally it won't connect at all for weeks, and sometimes it'll pop up an error from the taskbar saying "this USB device is unrecognized".
I attributed some of these problems to a faulty hard drive I had, but had gotten replaces. It honestly feels like they built me a laptop out of the faulty parts bin. I think these problems could be attributed to the battery or it's connection being faulty (which would suck because that's under a separate warranty that expired), or that these problems are from individually faulty part, or even a combination of both.
