My Dell 5320 laptop ignore its battery charge thresholds. It charges above the stop threshold and continues charging until I disconnect AC power.
In bookworm, I tried the smbios-battery-ctl command included in the smbios-utils package. In trixie, smbios-utils has been removed but tlp claims to do charge thresholds. From the output from 'tlp-stat -b', Plugin: dell Supported features: charge thresholds Driver usage: * natacpi (dell_laptop) = active (charge thresholds) Parameter value ranges: * START_CHARGE_THRESH_BAT0/1: 50..95(default) * STOP_CHARGE_THRESH_BAT0/1: 55..100(default) Yesterday I used fwupdmgr to update the laptop's firmware. It succeeded but made no difference. In the laptop's UEFI, 'Battery Configuration' is set to 'Custom' and shows thresholds that are reported by tlp. If I change the thresholds in the UEFI, tlp reports the new numbers. Likewise, if I change the thresholds with tlp, the UEFI shows the new numbers. It shows every sign of working except that it ignore whatever numbers I set and keeps on charging. Any help welcome. -- Nick
