It works.. after poking around and found nothing obvious.. I reasembled it and the trace is back after some noise of relay clicking.. not sure what is the cause of the problem but it could be one of the relay is stuck... tried to power on/off several times and it seems fine now..
Btw - is there a way to test the nvram battery onboard ?... its a dallas DS1742W-120..
