I had the same issue some years ago after I opened my 48g.
The reason would be in yur case that the main board is not making
contact properly with the keayboard. The signal of the keys is
introduced to the main board right below the screen

Try turning it on but pressing the metal cover just above the the "C"
key. (In fact, it worked better for my between the "B" and "C" keys)

If it works, the problem is that the main PCB might have loosen. You
can 1) Get used turning it on and off that way (althow you might
program another button for the off function) 2) Hit it hard by a side
with your hands hoping luck fix it (it worked to me in some 49Gs when
the screen became crazy) 3) Try open it and tighten the board again.

I recomend #1

Edwin, Thanks for the advice. I tried your suggestion of pressing
above the B and C keys and using the on/off button. That works
perfectly. Is there any reason to try the distilled water wash
suggested for dirty HP48's? I don't think mine has ever had anything
spilled on it but it is 10+ years old. Thanks.

Wow... I've never read anything about cleaning with distilled water...
Sounds creepy. I wouldn't try that, but maybe its better than opening
the hp... the scars never dissapear. However I don't think water could
be good for electronics... maybe try the compressed air suggested above
without opening the HP...
