At my office we have different R52 notebooks from IBM.
The notebooks are about 3 Years old.
Since 2 weeks we have with 3 or 4 notebooks heating problems.
The CPU temperature is about 80/90 degrees, with normal use.
Whe have checked that with "Notebook hardware control"
Because of the high temperature CPU, we lost performance.
Do anyone regonized this problem, because al the problems comes at the same Time on 3 or 4 notebooks.
Is it maybe a mainbord problem in this R serie.
Thanks for the response,
With kind regards,

open up your laptop check whether there is dust build up in the laptop.
Follow this manual if you don't know how to open laptop up.

I had the same problem with my R52 about 7 months ago. I tracked it down to the display driver.
For some reason, the machine had started to use the generic, software-based driver instead of the ATI driver. This meant the CPU was doing all the graphics processing which was making the display slow and the CPU extremely hot!
Check which graphics driver is in use. It may well be the result of an automated Windows update that has interfered with your configuration.

About 3 months ago I inherited R52 as a freebie.
The owned was fed up with buggy, virus infested Windoozie and the fact that the laptop would turn off itself randomly.
I immediately put Linux Ubuntu on it...and noticed that the frequent shutting off is due to CPU overheating.
CPU would routinely ran at dangerous, near meltdown temperatures of 80-95 Celsius.
The problem persisted even when I disengaged the fan control and put it on Max, 5400 RPM.
In the end , I removed the heat sink and cleaned , dust-blow the fan thoroughly and I noticed that the thermal insulation between the CPU and the heatsink was 'dried out' (the laptop is 5 years old by now) - so applied ZALMAN thermal grease quite liberally .
That did it. The CPU temperatures are 40-45 C at idle and rarely exceed 65 C even under heavy load.
Thinkpads are extremely solid machines and worth keeping.
Hope that does the trick for you as well.
