Question : Problem: Thinkpad T60 Beeps 4 times then Shuts down...No Video No Bios

I have an IBM thinkpad that Beeps 4 times and then does nothing. No Video...No bios. I press and hold the power button. The lights turn off, then restarts with the same beeps.
I have tried this with no battery (Just AC cord) and with Battery only.
I read that the four beeps have to do with a "security Chip?"
Any suggestions on how to fix this?
