High cpu usage in sleep mode

CPU history in sleep mode

when I put my laptop (dell inspiron 5401) into sleep mode, as you can see the cpu activity in a few minutes of sleep mode, and fan is turning in full speed.

This problem occurs in both ubuntu 18.04 and windows 10 LTSC.

I don't think that it is a problem but let me say, since I don't have sleep button I added a shortcut to f9 that puts pc into sleep mode. I deleted that shortcut but problem still continues.

If the issue occurs with two very different OSes, that would point to a hardware-specific issue. Have you updated the notebook’s firmware?

I have updated bios. I am using this pc for about a year. When I choose cpu on nvidia x server, I barely hear fan sound and not much battery drains. Now it is selected NVIDIA(performance mode), yesterday I put my laptop in sleep mode at 100% battery in the morning it was 75%.

I solved battery drain problem on ubuntu(not yet on windows).

When I LOCK SCREEN (by clicking lock symbol on top bar), problem continues. I created a shortcut on settings that puts PC into SLEEP MODE.

Use the process:

Settings → Search shortcuts → Add shortcut(at bottom) → Command: systemctl suspend

and add whatever key is empty in your keyboard.
Done.

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.
