    When I run my uMB on battery, I can't seem to run an external monitor on it.

    Is this normal?

    Thx

    I can run an external 50" HDTV on my MBP on battery so you should be able to.

    You can do that just fine, but you have to be using the external screen before unplugging the power. So plug the screen in, have everything plugged in, and then unplug the power while the monitor is on, and you'll be fine. ;)

    if you mean with the screen closed on the laptop, yeah... its a pain.. easier to just run it with the screen open on the laptop. You can switch the external monitor to the primary monitor, and turn the backlight off on the secondary... not the best way to do it, but it works.

    In the case you're talking about, you can download a program called InomniaX, which allows your external monitor to run with the lid closed on your notebook. ;)

    The only problem running with it closed is it needs power, and keyboard/mouse plugged in... then it works fine. The program you mention is a way to get around that yes, but as far as I've seen it hasn't been updated in awhile, and doesn't work on some of the newer lines of machines.

    Right. ;) It works fine on my machine though! :) I agree, it hasn't been updated in a while, but hopefully they can fix that.

    Isnt the screen still on though when you use insomniax? Wouldn;t that cause some damage to the machine?

    Nope, the computer screen is completely on sleep. ;) The only screen that is running is the external monitor.

    Yes, it could, by overheating if you use it for a long time like that. ;)
