---------------------------------------- Bug #427: x200: Two battery charging issues https://ticket.coreboot.org/issues/427
* Author: Akura Ryu * Status: New * Priority: Urgent * 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. 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.
## 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.

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.

Hi Angel!
Seems that I had tried some ectool command snippets in this thread: https://ticket.coreboot.org/issues/38. I used to try them to configure threshold, but they are not suitable with X200, and may cause unpredictable bugs.
Can EC be _fully_ reset by unplugging power supplies?

Hi,
Yes, the EC should be reset by unplugging all power supplies, as it loses power. The RTC/CMOS battery shouldn't matter, but it would be a good idea to disconnect it as well if it's easy to do so.

I've unplugged all those power supplies. Thresholds had been reset.
But when I plug in AC adapter while power off, then boot Linux, Issue 1 still exists.

Now battery threshold seems to work well when connecting adapter after system boot. But Issue 1 still exists.
Here I summarize when Issue 1 occurs: - Connect to AC adapter when X200 is off. - **Charging capacity reaches `stop_charge_thresh`.** KDE shows "battery is full" even though adapter has already disconnected (normally it should be "discharging").
