Device restarts after sleep mode.

the_doc · 06-25-2016, 04:15 PM

Hi

I have a Kobo Mini with KOReader version 2015.11-483.
If I leave the device in sleep mode while being in KOReader (pushing the power button), the sleep mode seems to work, but after several hours when I check my Kobo it is in Nickel. It seems that after a time it restarts on its own.
Imho, normal behaviour should be to stay in sleep mode in KOReader or turn off the device after some time.

How do you launch KOReader?

the_doc · 06-25-2016, 05:31 PM

with fmon.

Figures. KSM is much preferred. Hopefully, someone still using fmon can address your issue.

Luck;
Ken

KOReader probably crashed during the standby.

cf. https://github.com/koreader/koreader/issues/1974

Your input might be interesting, since you're using something other than a H2O

Tell me how to help.

Start by checking your crash.log, my guess is there's a "Segmentation fault" in there

.

Well, this behaviour is random and today it hasn't happened. But there is something in my crash.log
