*Remove all batteries (main battery and RTC battery).
*Patch the bios and make sure to verify it so there aren't any errors when writing.
*Hold down the small switch on motherboard
*Connect charger (laptop should start automatically)
*Wait. It might even take minutes and laptop will beep/restart a few times.
