Dead 3400c - sort of... Maybe power adapter?

[Opardalis]

So a weird event happened. I was using my PB 3400 (PATA SSD), then all of sudden, BEEP, it reboots. There was no battery, and it was connected only via wall power adapter. Upon bootup it failed to do anything, it would chime, then thats it, just hum, nothing on screen.

Is it possible that its a bad wall adapter? I see newer replacements are in ebay.

The computer is apart now because I am having it re-capped (the motherboard, PSU card, and small screen card).

If the issue was cap related, then it will be resolved. I just hope something else didnt blow on the motherboard.

Umm, did you by chance ever remove the PRAM battery? they are known to leak and destroy the logic boards in the 3400c and they start doing the things you describe.

Yeah, pram has been out for awhile. I was just using it a bit before complete tear down so I can redo the caps. I do have a backup motherboard, but was curious if the ac power adapter maybe fried and was supplying bad voltage.
