Battery drain during sleep. System suspended before kernel suspends all tasks

[Dr. Dennis]

Description: Ubuntu 16.04.6 LTS
Release: 16.04

I think this is similar to: Bug #1825636
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825636

Machine: Lenovo ThinkPad L390, fresh install

Suspend drains the battery in approx 1 day.

journalctl -b | grep -i "should not be sleeping" returns:
"cache: parent cpu1 should not be sleeping"

for all cpus

This is a real problem, as I rely on suspending frequently!

The laptop is quite new, it should use s2idle (Modern Standby) instead.

Also can you please try 18.04 or 20.04?

[Dr. Dennis (adennis)]

I know if I understand. After I suspend, I can see that the system thinks it's going into deep sleep, based typing this:

sudo journalctl | grep "PM: suspend" | tail -2

which returns:

Jul 29 14:58:15 SheRa kernel: PM: suspend entry (deep)
Jul 29 14:58:15 SheRa kernel: PM: suspend exit

As I understand it s2idle would be a less battery efficient state for it to report here.

However, the battery is still draining, and the cpus are still return this "should not be sleeping"...

Also, I unfortunately cannot upgrade to 18.04 or 20.04, as a good number of my bioinformatics pipelines are not compatible.

Thank you.

Is there a BIOS option that can be selected to "Windows" or "Linux"? Please choose Windows instead of Linux.
