Hi there,
Been a quiet PBP user since july 2021, really love my pinebook and enjoy it (using manjaro).
Lately I have an issue with the power button.
Symptoms:
It seemed that it won't boot properly, despite no recent OS/FW updates and topped-up battery.
It would boot into a certain state where the LCD is lit up and a flashing '_' is flashing at top left corner, as expected.
Then, the flashing is halted, then continues until shutdown. The PBP reboots, ad infinitum.
From time to time it did load GUI to show the mouse pointer before resetting, rarely loading the login screen.
Another thing is that shutting down resulted in reboot. Long press on power button did shut it down for good though.
Lately otherwise it ususally make it into login without turning off.
Making a long story short, in the rare cases I managed to log in I got constant power-off dialogs popping at me.
That's a typical journal log I get on the machine (reverse order):
Well you get the idea. That's really annoying.
I could probably remap the power button? But I do fear that the underlying condition will kill the power button altogether one day, and I wont be able to properly power the device on.
I took a look at the schematics. I guess that something is pulling the CPU power line, but not the PMIC one? Or is the PMIC less sensitive to that signal?
If it's the first issue that it's not a keyboard issue, and I have no clue what issue it is.
I might be able to sense the proper test points later, but I'd rather ask here first if anyone had such an issue or have any insight into this issue (I couldn't find such thing in the forum or elsewhere).
Kudos
