I've posted it in issue
#301.
So what happens exactly is that
- I find the Nickel Sleepingscreen is on display with the light on.
- I pull the power button. The light goes off and a popup states: Standby.
- I pull power again. Koreader activates and light goes on.
- Kobo Aura goes in non-responsive mode rather fast (10-20s). Even if I keep changing pages.
- Pull power again go to standy and regain activity.
- Kobo Aura goes in non-responsive mode rather fast (10-20s).
- etc., etc..
Only thing to do for a working sleep function is kill the light before the Kobo Aura goes to sleep and
reset Nickel sleep timer after power is back on.
