Battery drain after laptop's shutdown

[anajorgealmeida]

Since I upgraded my OS from Ubuntu 20.04 to Ubuntu 20.10, I have noticed a significant battery drain while the laptop is off. I have asked on ubuntu forums, where other people are having the same issue as me, but the common way to solve it is through an option called LAN Power Saving in the laptop's BIOS, because it happens due to the fact that the laptop's USB ports are still powered even after shutdown. I don't have that option available nor do I have any option remotely similar to it. 

It is a big issue for me because my laptop is two months old and I worry that this massive battery drain will have long-term effects.

I have been experiencing drains of 5 to 10%.

I hope someone could help me.

Thank you.

I'm sorry, but HP only warranties their PCs for usage with the OS that comes preinstalled.

IF you replace that with a Linux distro, or add a Linux distro, then you assume full responsibility for maintaining that -- including solving any problems with booting the other OS and/or installing the other OS.

Your best bet for support now is to contact the support forum of the distro you are using.

Since you are using Ubuntu, go here: https://ubuntuforums.org/

Good Luck
