I suppose this bug isn't hardware-specific.
Ubuntu kernels have CPU load balancing turned on, thus generating many
rescheduling interrupts even under idle load.
And if CPU-intensive process is running, load balance ticks goes up to 500 per
second.
This is not powersave friendly behaviour, but I
I guess this isn't going to get resolved before Karmic is released. Is
there something we can do to help get this on the radar for Lucid ?
What information can we provide ? Do we need to start testing with 2.632
? Pretty desperate to have this resolved.

Hi,
I just realized that I forgot an important piece of information:
post #21 concerns a thinkpad X200s, Model Name: *74695HG* Part Number:
*NS45HMD.**, 4GB Ram, SSD
and the undervolting settings were not altered.
Furthermore, I have one more output for a thinkpad X200, 7470A98, 4GB ram, SSD
attached output of
cat /proc/acpi/battery/*/state
cat /proc/acpi/battery/*/info
sudo powertop -d
on unmodified, up to date Jaunty with stock kernel and with kernel
2.6.30-02063004-generic for comparison, laptop X200s 7469-5KG (with
additional 2gb of RAM)
hope that helps

I think this bug is serious enough to get attention. This might also
help other notebook users with low battery life.
Andy, any updates on this??

I have followed your instructions. I fully charged the battery, turned
off wi-fi via the RF kill switch, ifconfig eth0 down and turned of wake

instructions.
Then i pulled the power and waited 20 minutes. The attached file

I can confirm this also on an X200-S (the updated model). Battery life
MUCH shorter than it should be under Ubuntu. (4 cell -- ubuntu ~1.5hrs,
Vista gives just under 3 with similar usage) This is a big issue as the
laptop was purchased spescifically for its long battery life when on 9
cell battery
Seen on several laptops of the x200 (and x200s) series.

hi,
I have noticed different power consumptions on different X200s laptops!!
My original X200s, NS45HMD, uses approx 1.5W less than my temporary
replacement machine, which is a X200s, Type 7470-A98.
I am attaching my output for
uname -a
powertop -d
lspci -vvv
The output is based on the

One thing I noticed is that powertop reports:
