I get roughly the same on my z61p running Fedora Core 7, maybe a bit less.
Did you already try powertop? It should help to increase battery life
a little, but you will never be able to get the 5 hours from windows.
There are also some other ways to tweak things, like the kernels
laptop_mode and a script collection named similiar... but I just
started to look into things so I can't tell you much more :p
Some links I found:
