I have had the worst computing and support experience in my life thanks to this very laptop.
It started in January, when the first one i ordered would run for about 15 minutes [watching videos on that lovely bd-rom] and i would get screen flashes, win7 saying that the display driver stopped working but recovered. This quickly accelerated to full-stop with no chance of recovery on the advice of their tech support, whose supposed fixes successfully destroyed a month's worth of work just in time for tour.
The second machine came 6 weeks [really!] later after my tour which i had to resort to buying a different (and so far flawless) Asus with an i7. There was no claim of being broken or overheated or anything, but i would say the motherboard fried by the time they were done diagnosing it or something, because this was a new machine again. But you see, the i7 is a very hot processor, it needs more than one pimpy, quarter-sized vent on the bottom to get adequate circulation. Even the lowest end i7 is hotter than the fastest Core2 Duo. Unfortunately even with the fans running as much as they can with such poor case ventilation, the CPU, GPU, and BD all emit more than enough heat to destroy your life's work if you're pushing the machine even a little bit. Plan on gaming with it? Good luck. My second machine started flipping out about 2 weeks into light usage, again mostly as an expensive BD-player and primarily internet. I went ahead and installed Torchlight on it just to have something to test it with and about 10 minutes into play the volume and tone controls started functioning on their own, each time the on-screen display being triggered and dropping me back to desktop. HP claimed it could be fixed by software YET AGAIN and i demanded a refund, which took at least 6 hours to get through to no less than 3 different techs and finally a manager, who still didn't want to give me a refund. Instead he insisted going through the boot manager disc he would send for free before moving forward with a refund or further service.
Fast forward to now, i just received the disc a few days ago and cannot get the machine to boot. i figure the HD died or something.
I hope that your machines do more for you than just break, and i realize i'm kinda late in posting this anecdotal evidence. But i'm not the first, you'll see plenty of bad reviews for the entire DV line of HP laptops if you search for them. If at all possible, i would advise getting your money back before the crap starts happening and drop $100 more for a better brand. HP will never have any of my money ever again.
