Does this have a Reset switch anywhere on the case? If not, it might be
a corrupted BIOS which can be reset by removing batter and external
power, opening the case and briefly removing the CMOS battery to clear
the BIOS. There is a sort of universal fix which works on some laptops:
remove battery and external power, hold down the power button for one
minute. Restore external power and see if it boot. Also, try this site
