I have a Mid-2012 MacBook Pro which had Kubuntu 22.04 LTS. I shutdown the computer overnight, and the next morning the computer started having issues. I believe the system may have corrupted the internal components.
Yes, I have an discussion on the support forum with Apple.
Yes, I did everything and waiting for more information to try.
Hi and welcome. I am very sure you are at a better place for help here, as the issues are likely OS related and not hardware.
It might be hardware, this is likely the case if nothing else fits.
We need a lot of more info to help you.
- what issues do you have? We cannot read minds

- output of
kinfo
- did you do updates? See the last changes of a possible update with
pkcon --history transaction list
if you used Discover, or tac /var/log/dpkg.log
if you use APT in the terminal. (does apt have a native tool to display update history??)
lspci
output
Cheers!
