My "Kobo eReader.conf" file has the following section:
Code:
[PowerOptions]
AutoSleepMinutes=15
FrontLightLevel=10
FullscreenCoverStretch=true
That sets it to sleep after 15 minutes, never power off and the light level is 10%.
Changing the power off to 30 minutes gives:
Code:
[PowerOptions]
AutoOffMinutes=30
AutoSleepMinutes=15
FrontLightLevel=10
FullscreenCoverStretch=true
But, changing sleep to "Never" gives:
Code:
[PowerOptions]
AutoOffMinutes=0
AutoSleepMinutes=0
FrontLightLevel=10
FullscreenCoverInfoPanel=true
FullscreenCoverStretch=true
ShowBookCover=true
SleepAccessoryEnabled=true
Absence of the "AutoOffMinutes" and "AutoSleepMinutes" options probably mean "never", but setting them to zero is the same and probably safer. The can be set to other numbers, but I think the maximum is 255. The "FrontLightLevel" is anything from 0 (off) to 100. The other options don't matter. But, leaving "SleepAccessoryEnabled" as true might be handy as you can put a magnet in the right place to put the device to sleep. Or set it to false if that might cause a problem.
