Hi Gileno,

Have you tried running it on the AC adapter?

What electronic test equipment do you have, and what experience do you have with electronic repair? The HP97 service manual is on the CD-ROM set. It contains full schematics of the machine. I'd start by checking the voltages on the Vss (+6.2V) and Vgg (-12V) lines. If the power converter circuit in a Topcat isn't running, the protection circuit tries to bring the battery voltage right down and gets hot-and-bothered in the process!.
