I was monitoring the other group, so I didn't see this post until now.
Interesting. I have the mouse being jerky right now. The network
adapter is on IRQ 16. And when I'm not moving the mouse, the CPU
shows 0% usage (on the Performance tab). When I move the mouse around
though, the CPU usage goes up to 20-30%. But the Processes tab
doesn't show any process that's taking up the CPU. The System Idle
Process stays at 99% usage when I move the mouse around.
Now I just disabled and re-enabled the network adapter. It's still on
IRQ 16. And the CPU doesn't go higher than 2% when I move the mouse
around.
The CPU is probably used by kernel drivers, so the usage is not billed
to any process.
In Task manager you can enable "show kernel times" then
the kernel time will be shown in red.
I can't figure what can cause this behavior.
If you don't have any 3rd party devices or software that
can be blamed, IMHO you should report this to Lenovo.
Also, you may want to ask in the microsoft.public.windowsxp.hardware
newsgroup.
