sounds to me like loose contacts. I'm not sure of the construction on one of these- I'm still a bit leery of taking one apart, but many HP calcs will have pressure connections for LCDs and if it gets loose, it goes blank.
try turning it on and typing 2000 <enter> 1 <enter> beep <enter> ?
(I really have no idea if it will beep with a loose LCD, but why not try?)

Flip it over and remove the upper right rubber foot. You will see a small hole. Straighten a paper clip and poke it through the hole until it bottoms out. Remove the clip and try turning on the unit. You might be alive again, if so, you'll be presented with the question "Recover memory?" Answer no to clear memory and you should be okay.
If that doesn't do it, try pressing on the raised part of the bezel above the B and C keys while pressing the ON button. If it comes on, the keyboard circuit has lost contact with the logic board. It will need to be popped open and fixed. Post a message if you need help.
Good Luck
