I own an Acer laptop with an i5-3210M (Ivy Bridge). It usually overheats and eats battery life but until now, I didn’t need to fix it. Now I need my battery and can’t use it for more than… 30min (windows makes it usable for at least 1h).
I’ve realized that when I run
watch grep \"cpu MHz\" /proc/cpuinfo I get always the same cpu frequency:
cpu MHz : 2494.338 cpu MHz : 2494.338 cpu MHz : 2494.338 cpu MHz : 2494.338
thermald as the wiki suggest for laptops, but nothing changes. I have enabled
powersave governor in all four cores.
Any help? I don’t know why the frequency is always the same either if I do nothing or run a big program.
Notice that even if I change the governor to
performance the frequency still the same instead of reaching 3100MHz as it should.
Thanks in advance!
