yes, still the same problems with shutdown, I fear that I messed something up in the process of trying ro repair the other problems.

Trying to shut down the system results in the monitor going black but the laptop stays powered (led’s still on etc.) for about 5 minutes, then it actually turns off but when booting up again, it says that it didn’t shut down cleanly and starts collecting data.
A reboot takes even longer and also ends in an error, saying there was a problem before finally shutting down and starting again, also claiming that the shut down wasn’t clean.
