I found the above on the Lenovo forums yesterday; maybe it's the GPU that's heating stuff up.. but the main thermal sensors listened to are on the CPUs? Is the GPU kinda central on the motherboard? Just that I do remember my laptop's underside getting warm especially when running on mains with the battery out ever since I bought the laptop (I used to cook batteries in an old Toshiba - so I often do that if I'm running mostly on mains at home).
Laptop fan kicks up to around 3000 periodically - but mostly being handled by the cooler at the mo.
Could it be that the GPU needs the fan to run longer and faster to cool it down?
Just that I did notice once when it WAS hot that the mouse would respond to movement but not to clicks. Could the GPU be thrashing? There were also these lines from /var/log/messages...
But with no shutdown action as these events weren't being handed off in Hardy...
But - since I bought the cooler - no heat issues at all. However, I DID notice CPU0 go to 100% when the GPU wakes up (I hit shift to wake the display up after leaving the machine for a bit)... in 2.6.24-24 (kernel that gave me grief), I did also notice a bit of a memory leak.
In -23 (my uname - Linux ubuntu 2.6.24-23-generic #1 SMP Wed Apr 1 21:47:28 UTC 2009 i686 GNU/Linux), it isn't immediately hitting swap, and running at about 100Mb less memory used with Evolution, Firefox (6 tabs), Sysmon, gedit. Unlike under -24, where there was a definitely memory leak (committed memory climbing towards 50% rather than 30 - I run 2Gb onboard).
Could this be a lead? http:// forums. lenovo. com/lnv/ board/message? board.id= R_Series_ Thinkpads& thread. id=3409
Possible heat issue with the graphics processor even with Vista...

Could the bugs be in -24-restricted?
