[Bug 1886920] Re: Battery drain during sleep. System suspended before kernel suspends all tasks. Lenovo ThinkPad T460

I was wrong, D0 is the correct state for the device, which doesn't have
PM capability.

Can you please install powertop and see the Package C-State count after S3?
In addition to that, would it be possible to see how Windows behaves?

Title:
Battery drain during sleep. System suspended before kernel suspends
all tasks. Lenovo ThinkPad T460

Status in linux package in Ubuntu:
Confirmed

Bug description:
The same as
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825636.

kaihengfeng closed that one "Because there's no response from the
original bug reporter." and asked to file a report for all devices
affected, so here I am, duplicating the report.

On Ubuntu MATE 18.04, as well as after the update to 20.04, the
battery drains about 1,25% per hour of sleep (if I just close the
lid).

$ cat /sys/power/mem_sleep
s2idle [deep]

tlp was initially installed on my machine. However, this behaviour also occurs if I
$ sudo apt purge tlp acpi-call-dkms && sudo reboot now

also, it occurs when booting from a freshly made MATE 20.04 live usb
stick, so TLP shouldn't be the culprit.

All the log files look in all relevant aspects similar to what was reported in the old report. I'm happy to provide log files from my machine, if any are necessary.
