Hi @nsariego ,
I could see you did not read the post I suggested you. May be, there is a problem in the auto suspended mode in the tlp settings. I wonder whether it could help you to solve the problem following @Wollie guideliness.
There is anothe post you could read the following post, where @Seabass gave a hint on a posible source for this problem and a solution?
‘Timed Shutdown/Hibernate during SSH Session’
Regards,
