http://ubuntuforums.org – I want to install Ubuntu. But my final concern is whether I'll be able to get drivers or something similar to make sure the functions that work on this laptop under Windows 7 will also work under Ubuntu. For example, I'm worried about decreased battery performance since this laptop with Windows 7 has some features to save battery life. I'm also concerned about shortcut keys which I use to toggle WiFi on / off, etc. and I'm thinking the shortcut keys on the keyboard may not work after I install Ubuntu. I did a Google Search but couldn't return much. I know this is a popular laptop model. (Hardware)
