Laptops :: your runtime on battery

greets to all,

i just wondered how long your laptops can run on battery.

my compaq armada 7770dmt runs 130 minutes on battery (in full use: installing, surfing, hearing music). i think thats not bad for an notebook from the 90's.

and i'm curious if the runtime improves if i remove the harddisk and exchange it with a compact flash. (my cp card is in the mail)
