Thread: 100% CPU Usage

Windows 7 Professional x32

Having the same problem here!

cpu: HP compaq 8510w

Windows 7 Professional x32
Intel(C) Core(TM)2 Duo processor (2,50 GHz)

When I don't charge my Laptop it works fine, but as soon as I plug in my recharger the CPU usage shoots up to 100%. When I run the task manager and resource monitor it gives the following percentages:

perfmon.exe 31% (the resource monitor)
taskmgr.exe 29% (the task manager)
sidebar.exe 9%

the rest of the processes vary from 0-5%, all normal I guess.

When I unplug my Laptop the CPU usage returns to normal and my computer works just fine. I'm starting to think it's a Windows 7 problem, but I hope someone can help me with this.
