Hello guys, Just coming to tell that i also have the L501X A04 and this worked for me too. My battery that used to last 1:50h in Linux now lasts 2:50, that's a HUGE improvement. Thank you.
Oh yeah, for the newbs in Linux (like myself) you should do a "chmod +x nvdown" otherwise it won't run the script. It was my first time dealing directly with scripts, so I didn't know that. =) I am preparing a guide of "Things to be done before using Ubuntu x64 10.10 in your L501X". Just like the guy did for the Asus U35JC on the link. Do you think it's a good idea? Where should i publish it?
