Public bug reported: When I close the laptop lid, the laptop appears to suspend, but when I open it again, the power light comes on, but nothing else. The caps lock light won't go on, and the laptop restarts after about 20 seconds.
Laptop: Dell XPS 9350 This happened on 16.04.1 with kernel 4.4, but upgrading the kernel with linux-generic-hwe-16.04-edge to 4.8 hasn't helped: $ uname -a Linux tom-XPS-13-9350 4.8.0-34-generic #36~16.04.1-Ubuntu SMP Wed Dec 21 18:55:08 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux The relevant part of the syslog is: Jan 14 23:51:32 tom-XPS-13-9350 NetworkManager[1063]: <info> [1484437892.4327] manager: sleep requested (sleeping: no enabled: yes) Jan 14 23:51:32 tom-XPS-13-9350 NetworkManager[1063]: <info> [1484437892.4328] manager: sleeping...
