[gentoo-user] Full battery laptop only 1 hour

["Guillermo García" <guillermo18barresiones@gmail.com>]

Hello guys,

I bought a laptop and i got like 4 hours of batter life, everything ok, 
(using more than 1 vm, etc), however now in idle my laptop has only 1 
hour of life, which is really annoying because its a brand new laptop 
bought one year before.

Here is my upower -d in case its necessary:
