As my Lenovo G50-70 ( core i7, 4GB, 17″ LED) to soo power hungry that i can’t even watch two episode of Game of Thrones. And hence, i was searching for power manager which could extend my battery life in exchange of the performance. I had experience with Jupiter previouly but later find out that it is not mantained nowadays. And hence find out about TLP. I followed this installation instruction for my Fedora 21 system.
Result
From initial observation i found out 30% backup time gain on my system. It never used to give even 2 hours of backup before but now it shows 3 hours and 15 minutes and ya gave me 3 hours of backup. Thanks tld.
