Ever since it was new (refirbished) I have been having an issue with the charging. The zaurus would charge for a while, then suddently stop and not start charging again. Since I did not bother returning it (bought it in GB and I live in Norway) I partially solved the problem by adding a timer to my charger, the timer is like the ones you plug between the wall outlet and the charger, and i set it to turn of he charger at regular intervals.
This is not a problem with the charger itself, I have the exact same problem while charging from usb with a cable I bought.
A year ago the battery was diminishing (but not broken) and the zaurus would last maybe an hour or thirty minutes on battery, then I read about the servicemenu and accidentaly reset the battery level so that it did not work for a full five minutes

My battery is a ea bl06 3.7 v
it's flashed at level 590 (3.7v)

Is it supposed to be charged higher than this? 4.2v? is it possible to make the zaurus allways stay on when connected to mains? Mine obviously does not since it cuts out when the charging stops.
edit: after trying the usb cable again it seems it is able to keep the z powered on, and battery seems better after my trials with charging the battery externally and resetting level in service menu. So it seems to be an issue with direct charging through the charger, fuse issue? Ill come back with updates later
