Hi,

I run XFCE and use Chrome browser, I use my laptop mainly for browsing and
for remote ssh to one of the university machines. I rarely do any other
stuff in my laptop.

I tried running PowerTop and found that my laptop always consumes 14-15W.
The number of wakeups from idle per second is also pretty high. I am
attaching the results of the powertop with this mail.

Regards
Nachiappan A
