Bug #427
Updated by Akura Ryu about 2 years ago
I've flashed my ThinkPad X200 with coreboot. Currently it has trouble when charging. ## 1. Charge state mismatch Cannot charge when battery level is below 20%. When I plug in my AC adapter, system always reports " **Not charging** ". Here's the output from the `acpi` utility: ``` Battery 0: Not charging, 23% Adapter 0: on-line ``` But weirdly, battery level is still increasing as the AC adapter is on-line. What's more, it still reports "Not charging" when AC adapter is detached (normally it should be "Discharging"). ## 2. Battery threshold doesn't seem to work. Since tp_smapi is unusable without stock firmware, I use `tpacpi-bat` to configure battery threshold. My KDE battery indicator can recognize these thresholds. ```sh sudo tpacpi-bat -s ST 1 88 # Start threshold sudo tpacpi-bat -s SP 1 90 # Stop threshold ``` But no matter how I charge, battery will always be fully charged. ## Revision - **OS**: Arch Linux with KDE - **Coreboot revision**: 93781523a - **Configuration**: See attachment
