I would like to try this, but I haven't the experience with
installing/configuring video drivers that most of you appear to have ...

Can someone point me to a post or tutorial which can lead me through the
procedure of installing and configuring the Intel HD Graphics drivers? I
don't even know the commands to show me which drivers are installed. I ha=
no idea that was possible for this laptop. I definitely only get about
4-hours battery time.

I'm running Debian (Wheezy), kernel 3.2, on a T520 (4239). I use i3 as a
wm (not Gnome)
