I have an XPS 9500 under Linux (this is a >$4000 machine), no amount of fiddling with BIOS settings (which are few) or systemd/GNOME settings will make it work reliably:
- short suspend time (it can't really stay overnight when suspended with a full battery)
- sometimes it wakes up and overheats in the bag
- very short battery duration when unplugged
Apparently I'm not alone, and even under Windows it's a generalized problem; and when you look for solution on Dell's forum you find this FAQ, which tend to say XPS are more foldable desktops than real laptops.
