Updating the BIOS on my X201s seems to have reduced the system

Embedded Controller update will modify battery charge algorithms to
balance battery charging and lifespan.
For me at least it turned out to be a hardware problem. After getting
the fan replaced I'm not experiencing this problem at all.

This appears to affect me on an X220 i7, 11.10 Oneiric.
This bug seems to relate to the OS and not firmware for me. I was on
11.04 previously and did not have a problem. During high-load the fan
would spin to a high RPM (don't know how fast since I never had reason
to check it but certainly
I agree with KC: I didn't have this problem with 11.04.

I had this problem on Maverick on a ThinkPad X201 tablet (computer
overheating and rebooting), and as a workaround kept my computer
underclocked (using the CPU frequency scaling applet for the GNOME
panel). After using that way for a while (maybe for a few months to a
year), I tried again a few
I didn't see that problem but once the fan speed had some sort of glitch
and went up to some extreme loud level (way more than 5000 RPM) and then
it just fell back to 0 RPM (sensors) while the temperature was at the
45°C range. Usually my x40 just sits around with 0 RPM and it's not that
clean
Let me ask one thing
Are you getting the same issue with both intel and amd processors
