CPU usage from 1 to 30% when moving the cursor

[fANAT1C]

Hello all

today I was bored so I randomly opened taskmanager and went to the performance-tab. My CPU usage was 30% in taskmanager when moving around my mouse cursor randomly (not opening anything, clicking anything etc). Then I had to do something downstairs, so went downstrairs with the performance-tab still opened, came back and saw that the CPU usage was 1%. But as soon as I moved my mouse the CPU usage went up from 1% to 30% in no-time. Though my laptop has no problems at all performance-related.

is it normal that the CPU usage goes up so high just because you're moving the cursor?

Specs:

Intel Core 2 Duo T6600 @2.2 GHz
4 GB RAM DDR3
NVIDIA GeForce GT 240m 1 GB

edit: and ofcourse Windows 7 Home Premium (x64)

Just tried it now and it happens to me. I doubt it will have much of an affect on anything though.

CPU: AMD Athlon 64 X2 5600 @2.9 GHz

doesnt happen on mine

I do not see that happening. Check in the processes tab of TM which process causes that.

i think its not a problem it just so happens on some computers

Well, the performance of my system is not going down but I was just wondering. Never noticed it before, though I think it was doing so all the time.

It depends on the mouse, how the ports are configured, it is usb or PS/2, what drivers for the mouse, etc.

First, 30% CPU use age is not high; although it is certainly higher than idle. My mouse will cause that sporadically. Other services can can cause it, too.
