This question already has an answer here:

hi I was trying to configure my laptop and went online trying to figure out about things to do after installing Ubuntu 14.04. I came across this.

Fix overheating and extend battery life

There is a good chance Ubuntu is not handling your fan, battery, etc. optimally but there is a nifty utility that probably will. Do this:

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw
sudo tlp start

but it seems to have made my laptop behaving weirdly but shutting down regularly after booting an entering password. how do I remove the whole package? please.

Also my graphics seem to turn a bit greyish for a mn or two before returning to normal.

I am using a Lenovo w510 Intel core i7 with 4gb ram and 1tb hdd.

many thanks.
