While testing (using) mentioned PocketPC device I encountered some serious

1.. Spontaneous HARD RESET - device resets itself when power on button is
pressed (impossible to always simulate but it usually happens when windows
media player was left active), couple times it reset while laying on the
table and nobody was touching it. No need to mention that all data was lost
in both cases.
2.. Battery indicator works oddly. After full charge it reads empty and
the unit shuts down. A two second connection to charger resets the indicator
to full and the unit works fine. Strange since the battery was full in the
first place.
These are the most common and most annoying.

Anyone encountered similar malfunction? Advices and solutions are very

Is there an OS upgrade available (PPC 2003)? Is the unit flashable?

Again, advices and solutions are very welcome!!!
