XPS 13 9300, Ubuntu 20.04, deep suspend not working

Question

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.

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
