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. -- Nicolas George
