Overheating Laptop

looks like you have problems with acpi. Usually it happens with "bad" 
bios. I recommend you to update firmware for your laptop first. (for 
example, my laptop had this kind of problem too, but 2 month ago my 
manufacturer fixed this problem in firmware.)


To be sure you can check if all acpi-related stuff was loaded properly
1. check loaded modules: lsmod | grep acpi
if everything ok, there should be acpi_cpufreq, and some other related 
modules (cpufreq_ondemand, freq_table, etc...)
2. check errors during boot: dmesg | grep ACPI, any errors/warning?

Good luck!
