    i'm curious; whats the maximum watts that your t400 has displayed?

    while max brightness, wifi, sound, dedicated..ive seen it spike up to27W

    oh and by the way, it's like impossible for me to get anything below 10 watts unless the computer is like off...

    I image with a DVD being burnt, along with some power hungry USB devices on all the usb ports, that number can at least double.

    Do you have the LED Screen in your T400 (maybe the reason why it doesn't get below 10w), or do you have your power manager in High Performance mode? There are a lot of variables in power consumption.

    it is os dependent. XP was 9.5-10.5 min for me. Vista is 7.5.

    for me it was Vista 10-14 and xp 6-9. I've had WAY WAY better results with battery life in XP, I'm at 7 hr's of battery life with a 6 cell battery with wifi on and lcd at 40% brightness!

    If you want to max out wattage I would suggest the following.

    Switch to maximum performance, and disable all shutoff timers.

    Burn a DVD at maximum speed (do this as a background process with high priority).

    Run 7zip, Handbrake or some other application that is properly threaded and can max out both cores of the CPU and spin the hard drive. Run this as a background process with low priority.

    Attach as many USB devices (bus powered hard drives with unpowered hubs would be ideal), Express cards, SDHC cards, etc. as possible. Run all these simultaneously if you can.

    Turn on ALL of your radios and start backing up files over Wi-Fi to a NAS, while doing a video conference in Skype, and syncing your smartphone over Bluetooth.

    Hook up an external monitor, and turn on discrete graphics. Run the timedemo from Crysis, Fear, or your favorite FPS game on this (foreground application, normal priority).

    I think 50 watts or higher would easily be attainable under these conditions. After all, the Thinkpads with dedicated graphics come with 90 watt AC adapters for a reason.

    This is of course a worst case scenario. Under normal office usage you should be able to stay under 15 watts (under 10 if you reduce brightness and use power saving features), and around 30 watts while gaming.
