Laptop not turning off 100% under Ubuntu (working fine under Windows)

[bubbabubbarda]

If you run:

sudo shutdown -h now

Does it power off OK?

Tried and no, it does not power off correctly.

You can grab a new kernel from here.

Create a folder, give it a name like linux.

download the linux-headers-generic, linux-headers-all, linux-image-generic and linux-modules-generic debs for amd64 and save them in the folder you just created (linux in our example)

then

cd linux

sudo dpkg -i *.deb

Then reboot. If the new kernel doesn't work. Reboot, press esc to bring up the grub menu, choose advanced option, boot into the previous kernel and uninstall those packages you just installed (it would be really convenient if you have synaptic) I linked you to the latest release but you can try other versions by going to the parent folder and choose from there.

Edited: if they tell you 16.04 they probably don't know what they are talking about and give you outdated info. 16.04 reached end of life in April.

Oh ok, didn't know that about 16.04. Anyway, I will wait for onboarding meeting on Friday and I will ask about this problem and maybe they let me update kernel.

Thanks all of you for your help

Any Updates on this one?

I handled this problem with deactivating the "hardware support for Lenovo ThinkPad L14 Gen 2, L15 Gen 2 from oem-sutton.simon-aenescumb-meta" within the "Anwendungen & Aktualisierungen" think "Applications & Updates" in english, but now this one don't helps anymore...

I have the same problem like you, [REMOVED SEE EDIT]
A few times it powers off correctly but most of the times not....

Would be happy if you already found a solution and share it with me

EDIT: [REMOVED: logged in user can't power off correctly without log in it works.] ->shutdown also dont works everytime when logged out.

Hi, I didn't find any solution but I stopped looking for it like 2 months ago or more. At the place I started working they let me use Windows so I installed Win10 and no more issues. I'll close this thread. Thanks
