I decided to open Task Manger on my laptop to see what the issue was. I soon noticed that a process called rundll32.exe was using around 25 percent of my CPU. I killed the process and everything returned to normal. A few days later, my battery was going dead very rapidly. My cooling fan was on almost constantly and was blowing warm air.

I haven’t had a problem with the rundll32.exe using up my CPU since I uninstalled Lenovo Settings Dependency Package.
