shiftux's questions

My computer drains a lot of battery when in sleep mode.

I've tried following the steps outlined in this bug report, tried the diagnosis layed out in this question and disabled the "sign of life" options in the BIOS as described here.

I confirmed my system sleeps in the s2idle state. Which I suspect is the problem.

$ sudo journalctl | grep "PM: suspend" | tail -2
May 13 18:41:00 mex kernel: PM: suspend entry (s2idle)
May 13 20:52:36 mex kernel: PM: suspend exit

However I have 2 issues when trying to follow the above guides: Firstly my /sys/power/mem_sleep file does not contain a deep option:

sudo cat /sys/power/mem_sleep
[s2idle]

And secondly I can't seem to edit the file to add a deep option:

$ echo deep | sudo tee /sys/power/mem_sleep
deep
tee: /sys/power/mem_sleep: Invalid argument
$ sudo sh -c 'echo deep > /sys/power/mem_sleep'
sh: 1: echo: echo: I/O error

Not being able to close the lid and have the laptop suspend is very annoying, I find... Any help on this would be greatly appreciated.

I tried updating my computer to Ubuntu 20.10, however it seems to have failed.

What I did:

sudo do-release-upgrade

This seemed to have worked, it ran through and the computer restarted with a gorilla welcoming me as new background image. However lsb_release -a tells me I'm still on 20.04:

$ lsb_release -a

Description:    Ubuntu 20.04.1 LTS (fossa-bulbasaur X38)

Running sudo do-release-upgrade again ends in "aborting"

I don't know in what state my system currently is... The sources all have groovy packets, the background image changed, but the OS clearly still is 20.04.

Would be glad for some help on this...
