Issue #427 has been updated by Angel Pons.
Could you please check if the "battery not charging" issues are still present when *not* using any software to mess with the thresholds? To properly test, please make sure the EC (Embedded Controller) gets reset: power off the laptop and remove all batteries and the AC adapter.
---------------------------------------- Bug #427: x200: Two battery charging issues https://ticket.coreboot.org/issues/427#change-1154
* Author: Akura Ryu * Status: New * Priority: High * Category: board support * Target version: master * Start date: 2022-10-14 * Affected versions: master * Needs backport to: master * Affected hardware: ThinkPad X200 * Affected OS: Linux ---------------------------------------- I've flashed my ThinkPad X200 with coreboot. Currently it has trouble when charging.
## 1. Charge state mismatch 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.
