HP Pavilion battery life poor with Ubuntu

Asked by PeterDz

I am running an HP Pavilion Notebook n268sa. Configuration is:

AMD A10-5745MAPU + Radeon HD Graphics sx4 + 8GB + 1TB disk
Graphics is Gallium 0.4 on AMD Aruba
Bios is Insyde F.13 (Insyde H20 setup utility R3.7)

I am running K/Ubuntu 14.04LTS with a mixture of utilities from both. I am running

I have got UEFI running because 14.04 is supposed to be able to handle it. Legacy boot is disabled.

Battery lifetime is poor, getting about 1 - 1.5 hours, which should be about double that.

I'd be grateful for any help.

Thanks
