Hi.
On my new Acer TravelMate Spin B3, running recent Bullseye, I have
noticed a strange battery drain when the computer is powered off: it
loses about 1% of the total battery charge every hour, which makes a
quarter of the battery in a day.
The drain happens when the computer has been powered down with poweroff
or an equivalent. I have checked, and it does not happen if I power down
with a long press on the power button (after halt). Therefore, it is a
sign of something staying powered with the normal kernel shutdown. I
have checked that wake-on-lan, wake-on-RTC-clock and similar features
are disabled in the setup.
Does anybody have an idea about what could be the culprit or how to
investigate?
Thanks in advance.
Probably something to do with USB-Charger feature.
