iPAQ 310 won't shut down

Hi,

I have been doing a lot of playing with my iPAQ 310 and SeeYou Mobile for
PNA. Somehow the unit is now in a mode in which I can't turn it off so that
it stays off while connected to the wall charger. Every time I turn it off
it turns itself right back on. If I disconnect it from the wall charger I
can turn it off and it stays off. I want to be able to charge the unit with
the unit turned off - to preserve the life of the backlight as much as
possible.

I don't think the unit did this when it was new. I have a customer's iPAQ
310 in hand and it will stay off while connected to a wall charger.

I must have adjusted some power setting, but I can't seem to figure it out.
The only thing I've installed is the screen rotate driver and SeeYou Mobile
on the SD card.

The issue occurs regardless of whether the unit is in SeeYou Mobile / WinCE
mode, or the street navigation mode.

I have rebooted the unit several times (soft reset) but I don't think there
is any way to do a hard reset. I tried removing the main battery for a few
seconds while the unit was turned on an that didn't help,.

Does anyone have any suggestions?

My next thing to try is to take the main battery out and leave it out
overnight.

Best Regards,

Paul Remde
