I got this laptop A70 Satellite for a year already. Last night, after being off for 3 hours, I turned it on back and it did so, but there was no display at all on the LCD. Gradually it sucked some nasty fuzz up against the grate, which I could then pull out. I have a Toshiba Satellite A75 that I have had for only five months, and I am beginning to have problems with overheating. If you do not have any important data on the hard drive try to run a restore CD, I guess you have nothing to loose and the laptop does not work properly anyway. Ok I tried the Video card removal, cleaning and reseating but it didnt work unfortunately.
