easy fix though:
- disconnect the power supply from the MB.

- remove the battery.

- take a screwdriver or whatever and use it to jump the contacts on the system battery. hold this connection close for about 30-40 seconds.

reattach the PS and put the battery back in and it shoud boot back up fine with bios defaults.
