I’ll start by saying that I fixed this issue by removing and putting back the cmos battery, and I’m more interested in ideas for why this happened.
I have installed an unmodified version of arch linux, xorg, etc…
Downgrade kernel to 5.12.15-arch1-1 x86_64, and linux-firmware to 20210716.b7c134f (because bluetooth driver issues) but otherwise up to date.
- I closed the laptop (I have not modified the default behavior of this, but it seems to put the laptop into a sleep state).
- I then left the laptop in this state unplugged for approximately 2 days.
- When I returned I saw:
a. No response upon opening the laptop lid.
b. Upon pressing the power button, the power button light turned on, the lights on the side flashed white, and maby green. No response from the screen.
c. After 10-ish seconds, all lights turned off.
d. I plugged in the laptop, charging light was orange, power button and screen were unresponsive.
e. The laptop charged for aprox. 30 mins, the charging light turned white, power button and screen were unresponsive.
f. I opened the laptop, two red flashing leds, unplugged and replugged battery, red flashing leds went away, power button and screen unresponsive, red leds return upon pressing power button.
g. I removed 1 stick (of 2), unplugged and replugged the battery, unresponsive, red leds returned.
h. I removed and replugged the cmos battery, unplugged and replugged battery, red leds returned, power button light upon press, both side leds are green (memory training mode). System boots normally.
Any one else have this problem?
I don’t know what to make of this, any ideas what would cause this?
Is there something I can change to prevent this?
