I reviewed your post and I understand that the advanced power options are missing.
Don’t worry, I assure you I will try my best to get this sorted.
I recommend you follow the below steps and check if it helps.
Method 1: Checking For System File Corruption And Restoring Default Power Plans.
Click on the Start Menu > Search for Command Prompt > Right-click on Command Prompt > Click on Run As Administrator.
Once the Command Prompt is up and running, type the following commands one by one and hit Enter after each command is executed successfully.
