Good day all,
I recently bought a IBM/Lenovo Thinkpad x201, full version with a Core
i7 620M. To get the most out of the battery, i keep the system as
minimal as possible in terms of software and services running. Running
powertop, it was showing me that it's the kernel itself generating the
most wakeups of all when wireless is off.
Booted into the laptop, just having the most basic services runnin not
even Xorg, starting powertop gives me the results you can see replaying
the script at the following locations:
http://laen.onedot.nl/media/code/lesswatts.org/powertop-time
http://laen.onedot.nl/media/code/lesswatts.org/powertop-text
$ scriptreplay powertop-time powertop-text
The [kernel core] <(null)> (<(null)>) line doesn't make sense to me. And
the amount of wakeups never gets below 4 cause of that. The kernel
config and /proc/cpuinfo are downloadable at the same directory:

Thanks in advance!
