For the past several days my Thinkpad T61 has felt hot. And I have two
CPU monitors in the Gnome panel, one for CPU0 and the other for CPU1,
and they have both been running close to the max all the time.
I tried Gnome System Monitor, but it shows nothing taking more than a
few percent of the CPU. When I run top it shows top as taking 95-100%
of the CPU (strange), but nothing else is ever more than 10%.
The CPUs running at close to the max all the time continues even if I
reboot and log in, but do not launch any apps at all.
According to Gnome System Monitor I have:
Memory: 3.8 GiggleBits
Processor 0: Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz
Processor 1: Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz
The two CPU monitors in the Gnome panel allow me to set each CPU
independently as to:
2.00 GHz
1.60 GHz
1.20 GHz
800 MHz
On Demand
Performance
By setting CPU0 to On Demand and CPU1 to 800 MHz the computer has
cooled down. However, performance has suffered a bit.
I doubt that it has anything to do with dust and such things because
it started suddenly just a few days ago. Moreover, I never saw the CPU
monitors running as fast as they have been lately.
Something is eating my CPUs, but top and the GUI are lying to me. I
need suggestions for other ways to find the culprit.
