Comment 89 for bug 1970957

Same problem, Lenovo E480 Ubuntu 22.04.01 LTS, it didn't wake up.

The only way to fix it (for me) was to manually update the kernel to the version 6.1.4-060104-generic.

I downloaded the kernel files from here (https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.1.4/)

  amd64/linux-headers-6.1.4-060104-generic_6.1.4-060104.202301071207_amd64.deb
  amd64/linux-headers-6.1.4-060104_6.1.4-060104.202301071207_all.deb
  amd64/linux-image-unsigned-6.1.4-060104-generic_6.1.4-060104.202301071207_amd64.deb
  amd64/linux-modules-6.1.4-060104-generic_6.1.4-060104.202301071207_amd64.deb

- save all the files in the same folder (e.g. Downloads\kernel6)
- run the Terminal, and select the folder where the file have been saved (cd Downloads\kernel6)
- run the command sudo dpkg -i *.deb
- reboot, enter in BIOS and disable "secure boot" otherwise you will get the error "bad shim signature"

Tested, close/open the lid. Pressing the power button (set suspend). All works great

Note: charged the battery to 80%, left in suspend mode for 10h, lost 10% (the battery was 70%).. too much.
