okay.... so im reformatting this lappy and it keeps shutting off mid-format... like after 10 - 15% it just shuts off. i thought it was a heat issue at first, since it has overheated and shut off before. so i tipped it up so the fan is exposed, put a room-fan about 8inches away from the bottom of the laptop, and tried again. and still it shuts off mid-format. what could this be? *ill leave this topic open for answers.... im going out of town for the night and will be back kindof late to answer any more questions. ** pc = gateway 400sd4 thank you for the help !
