Why is power settings not working in Ubuntu 22.04? Why don't I have performance mode?

Recently I switched from Windows to Ubuntu. When I was in Windows performance settings used to work fine. I was able to switch between balanced, power saver and high performance modes, but I noticed in Ubuntu my power modes are not working. Also I don't have the performance mode which is supposed to be the high performance mode.

The power saver mode doesn't do anything.

I searched the internet a bit about this problem and found out I can enable the performance mode using the command powerprofilesctl set performance and this changes the icon in the dropdown menu.

This changes the icon and that is it. I don't see any performance changes. When set in balanced mode powerprofilesctl command gives me this.

Balanced:
Driver: placeholder
Power Saver:
Driver: placeholder

and somewhere on the internet (I can't remember but it was a page related to Ubuntu) I read that it's a BIOS problem. Ubuntu does not have this feature on some computers (mine is Lenovo ThinkPad L450).

"*The power saver mode doesn't do anything too*" Your question should show the actual data you used to reach such a conclusion. Summaries lack detail that we need to offer useful advice.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
