2 to 2.5 hours with light usage

- 7800 256mb Geforce and Powermizer set to MAXIMUM POWER SAVINGS under battery mode. Windows XP power profile is set to laptop. And used MSCONFIG, deleted things in startup, and got rid of some things at startup in Windows services to reduce load.
Also have Bluetooth and Modem disabled in BIOS.
Screen set to MAX brightness. 80 Watt battery
Who wants this awesome screen with light so DIM you will think your looking at a 20W bulb.
But I LOVE MY E1705
