TW: Huge Power drain in Suspend mode
Hi, I use to close the lid of my laptop in the evening to put it in suspend mode. Mostly while it is attached to power. It is a Manufacturer: LENOVO Product Name: 20QWS0A8GE System Version: ThinkPad X1 Extreme 2nd Since some time - may be kernel 6 series - it reports an empty battery in the morning. After some minutes it is back to normal with full charge (as connected to power). So this first 'report' is obviously wrong. A second Laptop, T520 running TW as well, does not show this effect. Since recent (Kernel 6.8?) the system reports empty battery as above, but as well an aging of 100% of the battery - and by this, no charging of battery. I did a recalibration of the battery, after this it shows an aging of ~75%. (echo force-discharge >/sys/class/power_supply/BAT0/charge_behaviour) The next day, again the same issue. Anyone seen this as well? Any idea about the reason and solution? Thanks Axel

Update....not the battery is empty, it is just reported wrong, and does not update the charging status. I've created https://bugzilla.opensuse.org/show_bug.cgi?id=1223194 for this Cheers Axel
