When I talked to Megahertz, they said that they didn't bother with the power off setting because they claim that their modem, when it is not online draws very little power and it wasn't worth it. I think I will now go home and measure the truth of these statements. I seem to recall that when I last measure, my T1000SE with MHz modem and 3Mb drew 8ma in the off state. We'll see just how much of that is modem and how much is memory retention. But given 8ma: 1700maH / 8ma = 212.5 hours = 8.85 days, which is roughly my experience: a little longer than a week before the battery is totally drained. I wasn't aware of a 2000maH battery. My battery says on it 1700maH. Does the 2000maH say it as well ? One vendor talked about a 4000maH battery. I think he was lying. Cheers, Dan Ts'o 212-570-7671 Dept.
