https://bugzilla.kernel.org/show_bug.cgi?id=217024 Bug ID: 217024 Summary: asus-wmi: charge_control_end_threshold not restored after resuming from hibernation Product: Drivers Version: 2.5 Kernel Version: v6.1.11 Hardware: AMD OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Platform_x86 Assignee: drivers_platform_x86@xxxxxxxxxxxxxxxxxxxx Reporter: leigh@xxxxxxxxxxxxx Regression: No Created attachment 303716 --> https://bugzilla.kernel.org/attachment.cgi?id=303716&action=edit Rough and ready patch that seems to fix the issue for me Hello, Overview: I am running self-compiled Linux v6.1.11 on a ASUS Vivobook Pro 14 OLED (M3401). I have set /sys/class/power_supply/BAT0/charge_control_end_threshold to 75. Following resume from hibernation, although the value is still set to 75, the system starts charging the battery past 75%. Steps to reproduce (assumes you've set the system up to hibernate): 1. Plug in power supply 2. Set charge_control_end_threshold to desired value (e.g. 75%) 3. Wait for system to stop charging 3. Unplug power 4. Wait for system to hibernate 5. Power system back on to resume from hibernation 6. Plug in power supply Expected result: system will stop charging again at 75% Actual Result: system will continue to charge past 75% Build date: 11-02-2023 08:25:18 Hardware: ASUS Vivobook Pro 14 OLED (M3401) The attached patch seems to fix the issue, but I know next to nothing about this driver, so it may not be the correct fix at all (also has no error checking). If you need any more information, let me know. Regards, Leigh. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
