Hi Gents I left my ipaq 4700 unplugged for a couple of years and now it seems to be really dead. I plugged it in for a couple of days and hit the soft reset, nothing, no light at the top. Is there anyway to revive this little guy? Nick Kennedy

I have an 5555 that behaves is the same way. The main battery is fine but inside there is a little internal disk shaped one that holds a charge when swapping the main battery. Disconnecting and reconnecting this resurrected it from the dead a number of times. Its fine until left off power for over a few months or so.

It and its little brother are free at
