Thank you!
The full cycle goes like this:
- I boot with deep enabled via grub cmdline
- In Gnome I just press the powerbutton and the system goes to sleep (powerbutton is flashing)
- I then use the powerbutton again to wake it up
- It tries to come out of sleep (screen flashing once and the light on the powerbutton turns on)
- after maybe 5 seconds - the system turns off again as it seems to go back into sleep for 2 seconds (powerbutton flashing again)
- and then it is trying to wake up again and stays in this cycle forever. At my first encounter I let it in this state for maybe 10 minutes.
- When it is in that state, the fan starts spinning and is slowly ramping up until it is at full speed constantly
- I can press the powerbutton for 30 seconds and the laptop turns fully off
- I have tried letting it stay off for a few minutes
- When I try to start it again it goes immediately into this sleep cycle
- The only way to get it out of that is to remove all batteries (main and RTC) and start the laptop again
- BIOS is going through the full initial cycle with RAM training and then starts booting normally
- This is all happening on battery - there is nothing connected although I have tried it with power connected as well
I also tried a second SSD and installed a fresh Debian stable which showed exactly the same behaviour.
I am not familiar with this sysrq parameter but will try it out now and I am unfamiliar with this “REISUB” thing you mention. Can you maybe point me to a document explaining what that is?
Thanks
