I don't have the proper serial cables handy, so I'll have to wait - I
tried unplugging the keyboard, and the screen stayed black entirely -
no SRM line at the bottom. I'll get another keyboard tomorrow or
tonight to try - the one I have is an AT keyboard, with a PS2->AT
converter. Hopefully I haven't damaged anything... I'll try a true ps2
keyboard and hope :)
As for the other suggestion - I pulled the battery today and checked it
with a voltmeter - its putting out a bit more than 4v. On a 4.5v
battery, I'd say that means its probably still good. It looked like it
was not the original part.
