DECpc 425SE

[Antonio Carlini]

I'm working on a DECpc 425SE right now and I've not been able to find 
any useful documentation.


The laptop seems to work but has a BIOS password set. I suspect that if 
I remove the button cell then it will forget the password (or at least 
that's my hope).


The main battery comes out. There's no sign of leakage. It's a SANYO 
8HR-4/3A (510295-001).


The button cell looks very much like it is soldered in. It's 
approximately 12mm in diameter. I've read numerous warnings not to go to 
near a button cell with a soldering iron so I'm not really keen to do 
that, especially as I don't know for sure that it will fix the problem.


I've looked for a password reset jumper of pads but I can't see one.


I think someone has been here before me as the four screws that hold the 
two halves of the unit together are all missing.


Any hints welcome.


Thanks


Antonio
