I searched but mostly found bsod on wakeup nothing like this. never noticed this problem till recently because i never used to put my laptop to sleep, now i put it to sleep all the time. the thing is i can put it to sleep for a few hours then wake it up and everything is fine but if i let it sleep for like 8 hours then wake it up the power light will come on, the fan will spin and the hdd will spin, for a few seconds (not long enough for the screen to come on) then it just dies. and has to be restarted. what could this be. the only thing not factory on the computer is the fact that i put windows 7 on it. i downloaded all the proper drivers for it from dell support via service tag number then went through and updated them all so what could be causing this? its so inconvenient.
