Ok my friend and I here have a issue his computer wont even attempt to start after he got the blue screen of death and the computer shut off to protect itself at least that's what my sis said it said. Now During the time of this happening she was playing a game on the computer although the computer isn't meant for those types of games but handles them she had the computer on a pillow ( i already know ) now this i do not believe to be the issue although i could be wrong now this is why i believe that to not be the issue, we have a second computer almost completed identical to his same company same laptop different model they are the (Compaq cq57 and the cq56) now on his laptop we tried to release the power by unplugging power cord and taking out battery holding power button down 60sec's and plugged power cord back in turned it on and then off and but battery back in and it changed noting,we also tried that f9 or f5 whatever tick and nothing still it doesn't even try to boot up the lights come on and the disk tray works but that's it the touch pad lock and caps and wifi etc buttons are all unresponsive with their light coming on and off like their supposed to. Now the other laptop work's except for its cracked screen (never has been a problem) so we just used that one instead cause it wasn't broken then when we switched the hdd over from the broken laptop (cq57) to the working one (cq56) it started every thing but the screen and the buttons are also unresponsive on this one although it boots up we have tried all the same things on this one as well to try and get it to work oh and i forgot on both laptops we also tried to hook them up to my monitor via vga port and we got nothing it normally automatically switches over but not this time so we need help please.
