    iBook Dual USB - Cover Closed?
    I want to run an external display and keyboard connected to my 1.33Ghz 14" dual USB iBook. I had thought that I could simply close the cover and use the power button on an Apple keyboard to start it. Then, while researching the right procedure, I ran across the linked article. It looks like I 'must' run with the cover open. Is this similar to everyone else's experience? Any work-arounds? I guess heat is a big factor on these machines with the cover closed? It's a shame really, I have had many laptops over the years and this is the first one I have had with this flaw. Maybe Apple needs to spend more time on cooling solutions.

    The ibook dissipates most of its heat through its keyboard, closing the screen while running the computer would cause a lot of heat to be trapped and worse than that, a lot of heat on your screen. Not only would you be risking a lot of damage to your screen, your machine would be running a lot hotter than it should.

    If I were in your position, I would just use the screen spanning hack to use both screens.

    Yeah thanks. I just ran across some information on that. I'll give it a try.

    The Dual USB iBook was from 2001 (500 mhz G3)

    Your iBook is just the late 2004 model

    Well, the new iBooks have (2) USB ports, but anyway, is that article only refering to the 2001 iBooks? and if that is the case, is it ok to run the new ones with the cover closed. Apparently it is no problem on a powerbook. What is the difference?

    All iBooks from the 2001 dual usb model have had 2 usb ports, they just named the 2001 model Dual USB because it was the first to have the 2 usb ports. It is still not a good idea to run with the cover closed, you run the risk of frying your computer

    Apple says differently for a powerbook(see link)...why not an iBook?

    iBooks lids completely seal off the keyboard whereas there is a gap in PowerBooks. PowerBooks also have more ventilation out the back of the computer than the iBooks where almost all heat escapes through the keyboard

    Ok thanks for the info. I wish that it could be confirmed by an Apple article or information in the manual,, neither of which I can find. The problem with perpetuating old information about a manufactured computer, is that there is a possibility that the manufacturer has fixed the issue in the latest models.

    Here is a direct cut and paste from the mac help system on my iBook...

    Using your portable computer with the lid closed
    With some portable computers, you can use your computer with the display closed. For example, you might want to close your computer when using it to give a presentation on an external monitor connected to your computer.

    To use the computer with the lid closed, you must connect it to an external monitor, keyboard, and mouse. The power adapter must be plugged into the computer and an outlet.


    To operate your portable with an external monitor attached and the display closed:
    Connect a USB keyboard and mouse to your portable.
    Connect the power adapter to the portable and an outlet.
    Close the portable display to put the computer to sleep.
    Connect your portable to an external display.
    Wait a few seconds and then press any key on the external keyboard to wake the portable.

    I don't see a tight seal. There are rubber bumpers on the display lid that raise it off the keyboard surface.

    Those are to keep the keyboard from pressing into the display but the rim of the case doesn't leave gaps on the whole perimeter of the computer. When you are looking at the front of a closed iBook you can't see into the computer at all. With powerbooks you can see right into the computer.

    The Powerbook screens are considerably thinner... So heat can transfer much easier... They also have larger vents at the base of the screen than the iBooks do... and the fact they are made of a thinner aluminum type material also allows them to transfer heat easier.

    I'd rather have the heat coming out of the keyboard. Or would you rather have the heat spraying out on your lap?

    It's not a design flaw, IMO.

    No, I'd rather have it routed to a fan which pushes the heat out the back or sides like a properly designed machine should or minimally grills which allow the heat to flow towards the same spots..
