[Bug 1164557] Re: [Lenovo ThinkPad R60] Laptop to hot - VID to high



this is not easy to answer.

As I start with Ubuntu 10.x on my laptop I got hot problems at load. I
start then to add some packages (I not rember more which one) an dthe
problem disapears!

I have done an update to the second 10.x and I don't have any problem.

After updating to Precise first I see no problem, but short after I
occurs. This is because in normal usage, like internet writng viewing, I
got no problems. When I start cpu load activity like a lot of graphics
or video work  the laptop overheads an hangup.

I tried to figure out if I have done some mistake, like wrong governor
packages i.e. Also google gave no solution. One interestin point is: I
use the package thinkfan. I have it customized just after starting the
overheating problems at the beginning. After updating to Precise I found
that thinkfan was configured to use the fan in the level 0-7. Which
means max 3900 fan speed. So I found using google that there is a fan
level disengaded (which brings an fan speed 5800. I activate this under
precis for the first time. But this don't help to prevent overheading.
At 68°C cpu temp run my fan with 5800 revolution, what he have never
done before Precise.

This seems to be a serious and useable Linux problem: I often get
computer hangups if I use different Linux live system on many computers
to do a offline backup. When I then run parallel  partimage tasks for
different disks those computers hang. I guess overheating. Running the
partimage for the disks in serial get no problem.

To circumvent my problem I have writen a pearl script which monitors the
cpu temp every 10s and switch to governor powersave at 82°C and back to
conserative at 73°C.

Hope this explains in dead what happens regards Rainer

  [Lenovo ThinkPad R60] Laptop to hot - VID to high

Status in “linux” package in Ubuntu:

Bug description:
  My laptop goes to very high temperature. First I think it was a fan
  problem. I adjusted thinkfan to use the disengaged option. Now my fan
  is at maximum speed if the temperature goes over 67°C. But still it is
  not possible to run the laptop for a longer time an 100% CPU. It then
  overheats and stops working. For example just after clamscan starts
  working the fan is at maximum speed (5600 revolutions) and the
  temperature goes up over 85°C, the CPU usage is the about 70%.

  My standard governer is "ondemand". By using "powersave" the
  temperature will be about 5-10°C decrease.

  My investigation show me that in my opinion the VID is to high. To verify this I do the following:
  -  rdmsr -p0 [1] 0x0199 for every speed steps
  -  the governer "ondemand" switches the MSR 0x199 between
     - 0x0613, which means 1GHz and 1.275V?
     - 0x081c, which means 1,33GHz and 1.3875V?
     - 0x0b28, which means 1,83GHz and 1.5375V?
  > by 100% CPU the laptop overheats and stops

  - set the governer to userspace 1.833GHz
  - reduce the VID using: wrmsr -p0 [1] 0x0199 0x0b20
  > the temperature goes not over 65°C by starting load that goes to 100% CPU!.

  I see that the VID is always set to 0x0b28 when the governor change
  the speed to the highest speed. I don't know if the governor or an
  other kernel module set the VID The Sped (FID) is selected by the

  The FID/VID vor maximum should be set to 0x0b20 instead 0x0B28 and
  every thing would fine.
