hi all iam playing with a toshiba l305-s5875 i will just shut off when plugged into the power adapter not sure if it does it on battery power since the battery doesn't hold a charge long, when it does it . it is like all power is taken away just instant shuts down. i did remove the fan and clean it out good thing was plugged bad and looks like this laptop has gotten hot you can see some discoloration on the bottom of the keyboard and palmrest, i know the power button is seperate from the mainboard and so is the power plug but i just replacen it when i cleaned the fan out and yes it was doing this before i disasembled it, has anyone seen this before, iam kind of heading toward the mainboard but ill take sugestions if anyone has run accross this before. thanks all
