Re: X61 Speedstep and Fan problems

Try some BIOS Options - Config/Power. If you disable SpeedStep, clock is about 1100 mhz.

My settings are:

- Mode for AC - Automatic

- Modef for Battery - Battery Optimized 

- Scheme for AC && for Battery - both Balanced


This could not get so much better, but it`s worth trying.

Re: X61 Speedstep and Fan problems

Problem Solved. It is a mecanical problem in the fan.

The noise is caused by a vibration in the electrical contacts in the top of the fan. As soon as I pushed the three electrical cables that are connected to the fan, noise stoped. A qualified technician is required for the procedure.


ThinkPad X61 Hardware Maintenance Manual will give detail on how to remove the keyboard.
