Subjectissues with suspend on Dell XPS 13 2-in-1
From
Date
Hi All,

I have a Dell XPS 13 2-in-1 (9365) that when I supend gets warm and has
much shorter than expected battery life, it is about the same as if the
laptop just runs. I am currently running Fedora 28 with 4.16.2 kernel.

My laptop has NVMe for storage and is configured for AHCI mode in the
bios.

powertop by default shows
