Hi...

I am using a T42 since one year now. Since 2 or 3 months or so (after i upgraded my bios and EC i think), the fan of my notebook began to act weird:
Sometimes it acts just normal (starts at 55 degrees, goes up to 3500~4000 RPM on 60 degrees or so, and keeps my notebook below or at 65 degrees till the load drops)
Most of the time, the fan turns on and stays at ~2200 RPM (according to ibm-acpi readings). the fan also does NOT go faster, when the temperature raises. Under load the Temperature just keeps raising beyond 80 degrees (i did not want to heat it up
further).
Furthermore, sometimes the fan cannot be read by ibm-acpi although the fan is running (i took of the KB to see if it is)
Also IF ibm-acpi is reading that 2200 RPM (broken mode) and i stop the fan (with my finger) the reading drops to 0 RPM and stays there although the fan starts running again.

I searched the web for quite a while now, and i cannot find a similar thing on the net. Back then when this happened the first time, i thought that this is a Hardware defect, but yesterday the fan worked again, i shut down the system, took out the
Battery and pulled the power plug, after 2 minutes i plugged all back in, and the fan/EC was/is back (till now) to broken mode.

Has anyone of you experienced something similar, and knows a solution (besides sending the notebook back to IBM) to solve this?
