Hi,
Test it...
Screensaver 1min, 5min no problem.
Screensaver 15min, system hangs, only off/on will help.
Screensaver off, after 1564 counts (fast mode) system hangs, only off/on will help.
Clearly a bug.
Mine:
Firmware 2.01.01.37R2
Hardware 02-02-00-40-00
Martin
Edit:
It seems I don´t have the latest firmware installed - did you have it ?
Interesting: My firmware version seems not to exist in the revision history
@Tautech : Would be good if the systeminfo will display the hardware revision mentioned in the firmware revisions, F...G...etc.
