My motherboard is different from the one in your picture.
Shorting the power pins does not work. In this version there's a cable that connects the to the motherboard in 2 places and the IO board in one place that's supposed to facilitate this. I've doublechecked the bios, and "Pwr on after power fail" is set to ON, but it still does not work. The bios settings are being kept through power cycles... the battery is good as far as I can tell.
Any other suggestions? I'm especially curious about the system clock counting too fast.
