When I first got mine, after I'd used the battery for about a week I was getting about 4 hours and 55 minutes of heavy use out of the computer. If I dropped the processor speed, left it sitting (not suspended) and let the hard drive spin down now and then, etc., I got 6-7 hours easily. After I got a 8MB RAM card (for a total of 12MB) the battery time dropped down to about 3 hours 35 minutes under heavy use. With the 8MB RAM card, CPU speed set to high, and a large ramdisk, I was able to get about 7 hours of game time playing Doom on a full charge. If you account for the RAM card, this works out to over 9 hours doing the same thing with only 4MB. Drop the CPU speed to low and turn the screen off a few times and 12 hours seems like a reasonable upper end. If IBM's times for the 750 mono is any guide, their estimate is a little lie, high by about 10%. I do know *many* people are disappointed with the battery life on the color units. -- John H.
