Hi, I’m Nicole, I’ll be happy to help you out today.

CPU usage going up to 100% can be caused by multiple things such as a failing hard drive, virus/malware, or software that utilizes the CPU so much.

You can check this thread on this issue since there is a verified answer on that thread.

You can also do a full scan using Windows defender to check if malware or virus is causing this.

School laptops are just that, school laptops. They have very basic specifications, cause they're made for light tasks. This level of CPU usage is normal, specially when watching videos or using other resource-heavy websites/programs. You can try switching to a lighter browser, like Microsoft Edge, or getting a new device on your own.
