View Full Version : [ubuntu] Power management problem

July 26th, 2009, 10:45 PM
Hello every body,

I have a problem with a Clevo laptop, the battery with Ubuntu stays only for 25 minutes.

When i contacted Clevo's alway-busy Support Team, they gave me this answer :

Please append the kernel parameters "acpi_os_name=Linux acpi_osi=" when boot up

Could any body explain to me what this means ? I'm new in kernel things & i don't know how to change kernel parameters. and what they ment by "when boot up"? they ment that i have to change the kernel parameter while starting my laptop ? If yes, how can i get a menu or something to modify kernel parameters while booting?

Thank you for your help
