Issue #427 has been updated by Angel Pons.
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. ---------------------------------------- Bug #427: x200: Two battery charging issues https://ticket.coreboot.org/issues/427#change-1156 * 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. ## Revision - **OS**: Arch Linux with KDE - **Coreboot revision**: 93781523a - **Configuration**: See attachment ---Files-------------------------------- .config (18.8 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.
