Hello! I have an Asus A54HR-SX324V and run kubuntu 13.04 on it. I've been trying to solve a battery consumption problem since 2 months ago. I've googled and searched the ubuntu forum for a solution but so far I couldn't find anything useful. Is there anyone who had the same problem with a similar laptop or knows how to solve it? Someone says it's due to a conflict between the Radeon and the integrated video card, someone else says it's a problem caused by ACPI drivers.

The following information could be useful:


"uname -a" output:

Linux K54HR 3.8.0-33-generic #48-Ubuntu SMP Wed Oct 23 09:16:58 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Windows 7 battery duration:
About 3 hours, even in high performance mod.

Kubuntu 13.04 / Ubuntu 12.10 (tried both) battery duration:
less than 50 minutes
Also, according to the system, my laptop is an Asus K54HR, is that the same?
