So I have had this problem several times with the same laptop. I will go to sleep and when I wake up the laptop won't turn on. I do the RAM reset thing, remove the memory cards, but nothing. I'll just leave it plugged in and usually after a couple of days the laptop will suddenly turn on. Well, it happened again yesterday. I woke up and the laptop once again will not turn on. Can't contact dell support because they are absoultely no help. Thanks for any assistance you can give me.
