I am getting anywhere between 11-15 watt depending on wifi and contrast settings.

is there a software program that we can use, or are you manually figuring it out?

I haven't had a chance to check my T42 yet, but I have a Kill A Watt and it works great for finding out what your appliances are using for power.

Just one of many places that sell them: http://www.ahernstore.com/p4400.html

You can Google for many more.

I can get this information by clicking on the "battery information..." in the toolbar

My T40 uses 13 Watts when my screen is at half brightness and WiFi is enabled at highest power savings.

I've seen power consumption drop to as low as 8-9 Watts if the screen is turned all the way down, WiFi is off, and I'm not doing anything that requires much HDD access.

I use about 11-12 on average.

The pre-loaded Windows XP has Battery Maximizer installed. It's a long green battery icon in the taskbar next to the icon tray.

Click once on the battery and a menu comes up. Then click battery information (last item on the menu) to see the power draw, voltage, current, and other battery stats.

I've only had my T42 a week, and my battery information reads Fully Charged Capacity= 43.34Wh, BUT Design Capacity= 47.52. Is the battery just designed with a theoretical design capacity. Is this normal? How low would this capacity have to go before IBM would replace the battery under warranty?

how are you guys only getting 10-11 W ussage? I checked in the battery maximizer thing and it says discharging at 1.35A 12.09V and 16.29W ... could it be cuz im running win2k? I set the speedstep to max battery and the screen brightness all the way down.....

actually.. i just plugged my A/C back in and it went down to 10.02 at full screen brightness.. so I guess you guys measured it while the A/C as in.. was scared there for a bit that maybe they put a P4 instead of P4M in hahah

Pentium M and Pentium 4M are not the same CPU. A P4M is simply a P4 that is rated to run at a lower voltage than a desktop P4 and has SpeedStep enabled.

And you wouldn't have to worry in any case. The socket that the Pentium M uses is physically different than that of the Pentium 4.

If you plug the A/C you're measuring charge rate, not drain rate. A P4M and a Pentium M processor are completely different.

I get from 14-17 watts. It can go much higher depending on what I'm doing. I'm using mobile meter. It typically gives different readouts than the battery maximizer.

It's funny. I can actually feel the CPU getting warm in adaptive or max performance mode. It gets warm in a matter of seconds.
