Sorry for the poor title description. I am keen to troubleshoot the problem I am having without backing up the device and reinstalling the O/S.

Some details:

Device: N810
O/S: Maemo version 5.2008.43-7
Options: 8GB optional memory card installed
Applications: Many and varied
Problem Description: Device boots and performs well (apps are responsive) for some hours. Within 12 hours (and always within 24 hours) I experience the following behaviour:
- applications become unresponsive
- all 'extra' status bar apps reset (they are no longer displayed and the default set are present)
- all desktop icons disappear from the screen

Notes: In trying to isolate the problem I have rebooted the device without any desktop apps/icons present. Fault still appears (after some hours the device becomes unresponsive and the status bar icons reset to default set). I also note that the keyboard backlight frequently fails to illuminate when opened although I have yet to link this as a symptom related to my major issue.

I know the information is pretty general but am keen to find out what facilities and logs are available to help me isolate the problem further.

Thanks,
Alan
