Hello all.
Today, i finnaly solved my problem with linux, the shutdown.
I know i maked an other post with a posible solution, but after peppermint os 7 that solution i found doesn't work for me at all. (Im now in PM9)
So, after 1 year of investigating the problem, (is not a joke) i found a solution (or a possible really definitive solution).
Well, the things i made was that:
Go to
Then, put this line:
noapic acpi=force reboot=b
Then i updated the PM9 kernel 4.15 to 5.0 using uuku
Ok, then i go to BIOS and i set the ACPI enabled and the wake up for USB DISABLED.
Finally, i maked an
and all should be 100% fine.
That method FINNALY works for me, So its probably that it workds for you too.
