2 months ago No need to disconnect the battery to perform a coldboot. Just shut down, unplug wall adapter and wait a second.
The EC saves settings upon (graceful) shutdown, so you have to go through the proper shutdown, instead of hot-removing AC and battery completely

2 months ago Does it mean that the AC needs to be plugged in for a warmboot and without it the os shutdown results in a coldboot? In that case the Dasharo test specification needs updates because it says to remove the battery. https://docs.dasharo.com/unified-test-documentation/dasharo-compatibility/31G-ec-and-superio/#ecr025001-permanent-keyboard-illumination-after-cold-boot-firmware

Brief summary
The keyboard backlight setting changes after a coldboot
How reproducible
100% in 2 tries on Ubuntu and 2 tries on Windows
How to reproduce
Boot an OS, change backlight setting (alternating turned off and full brightness is the easiest to notice), disconnect all external power supplies and disconnect the battery. Connect the battery back, boot into an OS
Expected behavior
The backlight setting from before the coldboot should remain
Actual behavior
The backlight setting changes. In all tests the default was off and I have changed it to the max brightness. After coldboot it's always back to being off.
