I have a little problem. I bought a Pavilion G4 with Windows 7, but I really hate Windows, so I installed Ubuntu on it.
On Windows, the laptop's battery lasts longer than it does on Ubuntu. I've also noticed that the processor is constantly running, because on Windows the laptop's internal temperature is not as high as it is on Ubuntu.
I read something about wakeups and that some processes have 150 to 500 wakeups per second.
