HI guys,
Quite a few years back I got an HP4194A dead (not booting). It 's exactly the same chassis/cpu as the 4195A that I have a pair too.
When I got it, it appeared that the CPU board battery was dead, and HP carefully designed a circuit that could not start on a dead battery.
Damn HP, but wait...
The seller was a few km from me, so I paid him a visit to see how the unit managed to not start... Blank screen sounded good to me.
I tried to make him end the auction early but he insisted on having the auction go to it's end.
The auction was starting at Eur300, and I got it for Eur350 IIRC.
What I never told the seller is that I was ready to pay Eur1700 for him to end it early... (those units are expensive and I really wanted it)?
Then troubleshooting was 2-3 hours (had to reverse that bit of CPU board part) and a one hour trip to the next all-kind-of-batteries-seller.
Not so damn HP :-)
Now back to the battery question, I can't remember if it was a lithium or NiCd one, but it was a very common one and I could easily find a replacement one and you should too.
Just don't replace the NiCd with NiMH, but I guess you know that.
Thanks,
Fred
