I recently had a problem with my IPAQ 3950 rebooting itself at random
intervals, and thus losing my XCSoar installation.

Online searches suggested this might be because of battery failure, so I
installed a new battery (equivalent of US$15 via eBay). It's working
fine now.

Worth trying?

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,
