part 2 - laptop battery and... ubuntu?

[Jane Zhang]

Hello All,

I am noticing that with Ubuntu my battery lasts only half as long as in 
Windows. I'm getting the same error message as Helane. (Compaq Presario 
V2000) I think the main reason for this is due to the fact that by 
default Ubuntu does not have power-saving turned on. So......
Is Kpowersave what people would recommend for me to install? Are there 
any other powersave applications out there?

Thanks!
