Not the most important question, but:
I've got an older Compaq palmtop, series 2930A, that doesn't turn on.

I've tried resetting it, taking out the battery, etc...

I was using it a while ago, and it worked fine. A few days later, it wouldn't turn on, and all I can get it to do is charge the battery. No powerlight, etc...

I was using it with the ac adaptor both times, so the battery isn't the problem.

I've also got another one that doesn't turn on, which I can use for replacement parts if needed. I got them both(along with other stuff) used.
