The cpupower utility can be used to set minimum and maximum cpu frequencies and frequency scaling governor. I use it on my intel and amd laptops. With some governor you can't set frequencies, try to change them.I hope this helps.
echo 25 > /sys/devices/system/cpu/intel_pstate/max_perf_pctthis sets max frequency to 800 mhz instead of 2.5/3.0 ghz as usual.note that 25 is percentage, and on different core iXXX processors results can be different....I hope this might help Phyllis with her overheating intel laptop .....
