HP Omnibook 600c

Currently DEAD and not powering on, Loud pop and Magic smoke a few seconds after I plugged in a PCMCIA CD-ROM drive, I believe it stressed an already weak power regulator and blew it out, it had been whistling a bit prior to it popping so I believe it was on its way out already, CD-ROM just pushed it over the edge.

Currently waiting for a rainy day to work on this one, hoping its just a dead and blown capacitor or some other off the shelf part in regulator.

      I don’t have any software for it, but I do remember Win 95 had working mouse drivers, but I know 3.1 was a problem finding ones that worked. Unfortunately this unit is not working anymore, I still have not got around to fixing it yet.
