Well temperature is ok! There are mutliple thermal sensors and the standard=

temperature value that can be gathered through acpi is the value for the=20
cpu. According to a call with IBM, the pentium m can stand up to 94 C. You=

always compare temperature values to ordinary desktop cpus which is the=20
wrong thing to do. In Addition: the bios will shut down the system if it=20
gets to hot and I never experienced this, so I assume everything is working=

properly.

Try removing the cpu and sitting it back, then add more thermal (grease)?=

Why would you do this? In case you do sth. wrong or in case IBM realizes=20
this, you may lose your entire warranty...
