I am not sure whether this is isolated to me or a known issue but whenever I try to run the F12 diagnostic test on battery, it failed at LCD with the error core 3022 showing that it failed to change the brightness of the LCD. While plugged in, it passed all the test. Can anyone confirm this?
M17x LCD test failed running on battery?
