I'd start with cold start, hit enter, type beep, enter, and see if the CPU and os is running. Assuming that they aren't, check the reset line with a scope to make sure the CPU is being reset properly on power up and that it's not held low (I think it's active low) since the nimh is in play on this one.
Also check power supplies to the various chips.
