How to restart Pizmo PowerBook after no power for two years

Greetings!

While the charging cable is connected, gently lift UP on its connector jack and see lights come on or you get some other indication of charging. These internal connectors take a lot of abuse over time; lifting the connector slightly restores contact temporarily with the power board.

And I'm pretty sure your PRAM battery is bricked too--that can prevent starting. If you decide the power adapter is getting power to the computer, remove the keyboard and locate the PRAM battery cable. It can be seen as the red, white and black cable in the "Step 3" image on this site;

It connects to the logic board immediately to the left of the right-hand heat shield retaining screw. Disconnect it. With most Pizmos, disconnecting a dead PRAM battery will let them start.

If the comptuer then starts, you need a new PRAM battery. I've bough several G3 powerBook Pram batteries from OWC and they have worked fine. This is their offering for the Pismo:

Thanks for the greenie! I curious which of the methods worked. If it was the first one, there are steps you can take to patch the power board to maintain contact with the power jack without having to hold it with your fingers. If you need those instructions, let me know.
