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

Title:
[Lenovo ThinkPad R60] Laptop to hot - VID to high
Status in “linux” package in Ubuntu:
Incomplete
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
governor.
The FID/VID vor maximum should be set to 0x0b20 instead 0x0B28 and
every thing would fine.
