Just a reminder this lid message only appears upon entering firmware after a reboot from linux. Doesn't happen on entering "reboot" from firmware or a cold start. Noted one other "symptom": when I do the reboot from firmware, I do hear a little 'click' as the battery LED flashes, I don't hear that click on the reboot from Linux. It occurs whether doing a restart from the GUI on Linux or entering "reboot" from terminal. > > If it does, please get to the ok prompt, type lid-off and press enter > (to stop the timer), then test the lid switch like this: > > ok lid? . cr d# 500 ms many > After rebooting from Linux seeing the symptom and entering lid-off after entering the above command, saw fffffff fffffff fffffff fffffff . .
