[ltp] X200 Battery Life

[Andrew Mason]

Thanks for the information guys. I will have a look tonight when i get
home and report back later.


Also, I noticed last night in powertop that the acpi module seem to be
responsible for a considerable amount of wakeups. This was with 2.6.27
on Intrepid. Can anyone else confirm this behaviour ?

Another quick question for you all,
The fan was sitting around 3600 when it was hardware controlled
(according to Linux) but it was quite loud when i was viewing the bios
too, so has everyone had to use tpfand ? or should this be automagic
as well ?
