I have been using for two year windows + ubuntu, now I would like to switch off completely from windows. I have a little problem with ubuntu, it can't manage the power of CPU, GPU and the others components as good as windows does. For instance the temperature of CPU is about 40-45 °F higher than in windows, the same for GPU. Furthermore the battery has 15-20% minus life. I have tried from 8.04 to 10.10 (32 and 64 bit).
I also have installed third party driver for GPU (nvidia). Where could be the problem? Are there capability to set the options like in windows where you can choose the frequency of pci-e, motherboard, wireless, etc.
Thank you in advance
