Cool.. So... nothing to worry about there.

hehe.. It has already failed once. Called up DELL for a replacement.
Still Sucks.

Nope.. When I try to detemine the max of my batter life, I don't use the
CDROM at all, I disable Wifi, 600Mhz, laptop_mode, no usb, no sound,
(not using the speakers, but drivers still on) screen to dimmest(14.1
SXGA screen 1400x1050) etc..

2:30 hours.

so... I've stopped hoping / looking for ways to get my battery life
better. It just plainly _sucks_.

Where are you Art Fuel_cell?

(Unless of course I go get a N-Charge battery which will cause this D600
to feel like lugging around a piece of brick!)
