I recently set up an old laptop (HP 15-ba Series) as a home server. After a certain period of time, e.g. a day, the server seems to go into sleep mode.
Then I can no longer connect with SSH and the server is no longer accessible via the network.
Physically, the server seems to still be on. The fan is still running, but I can no longer wake up the laptop by pressing a key. I have installed Lubuntu 24 here. I have already tried the following to solve the problem.

I also checked the Power Management setting through Libuntu Settings. Notting seems to work.
Does anyone has a solution for this? Maybe it is a Hardware problem?
Thanks for your help!
