CPU stuck at 0.38 Ghz when charger is plugged in.

Thanks for your reply, unfortunately none of these suggestions changed anything and the CPU speed still immediately drops to 0.38 Ghz when I plug it in. Is there anything else I could try?

 

cpu stuck at 0.78 ghz when on battery speeds up to 2.67 ghz and slows down to 1.30 ghz.

hello, this is a copy of my old comment "helo" there are some diffrence because my laptop changed > My cpu fan is not working while plugged in so cpu speed is stuck at 0.78 ghz.

my computer is 2.30 ghz average speed. max is about 2.70 or more and cpu speed up to 2.70

ghz and my cpu fan goes to full speed when on battery, and then slows down to 1.30 ghz or 1.00 ghz. what causes this and how do i fix it? also i think there might be some errors on this comment, Windows 21h2. intel core i5-5300U. i tried to change power plan settings restarted my laptop a few times edited power plan settings max cpu 100% and minimum 100% i changed and it didnt work. it i s very annoying. the problem started now. also i tried to update my windows and didnt work

Look at the Performance tab and at the bottom click Open Resource Monitor, check if you are seeing only 1 core out of the 2, 3 or 4 on the CPU. I get different speeds depending on the core, usually waiting a bit will step through the cores.
