XPS 13 9300, Ubuntu 20.04, deep suspend not working

I have observed an issue with the Dell XPS 13 9300 where it cannot enter deep sleep. As a result, the battery runs down very quickly when you shut the lid. The machine originally came with Ubuntu 18.04, which has the same problem. I thought upgrading to 20.04 might help, but the issue persists.

I can tell the machine is entering s2idle instead of "deep" suspend by running the steps here. And here.

As per this thread, I tried disabling "signs of life" in the BIOS but that did not help.

The steps taken were:

- Make sure I have the latest BIOS.

- Disable "signs of life" in BIOS.

- Run "echo deep > /sys/power/mem_sleep" 

- Verify that this setting took effect.

- Then run "systemctl suspend"

No dice - the laptop cannot wake up and needs to be restarted. Anything else I can try? It's a frustrating issue since the machine must be powered off when closed.

Have you figured it out since then?


There are other threads here as well regarding this issue.  See for example.



Has this issue been resolved with the latest BIOS 3.03? I am running Dell factory installed Ubuntu 20.04 and I have the exact same problem, the bottom of the laptop will be warm while in suspend mode
