    Hello, ive got an iBook g4 2005 and have hacked the firmware using Screen Spanning Doctor and everything works fine. However, i cant get the clamshell mode to work.

    I read the manual and it says i need:

    - A usb mouse/keyboard connected to it
    - The iBook with the power cables plugged in

    And... and close the lid, which puts the ibook to sleep... then use a mouse/ keyboard to activate it and the display on the monitor should fire up. It doesnt work?

    Oh and PS - im looking to buy a Apple keyboard to use with the hack as well.. must it be apple branded or any cheap usb keyboard will do coz the apple ones are higher priced than "normal" keyboards.

    In your head.
    SleepLess by Alx Soft. Was once freeware, is now shareware. There is another application, but heck if I can remember it. The purpose of these is not to enable a featuer that already exsists, but rather to enable it with out the use of extrenal dongles. Good for WarWalking.

    Otherwise it's a USB mouse and keyboard to use the computer while closed. Do you have an external monitor hooked up? That also has to be present.

    At some point I thought this was disabled on some computers due to heat dissipation issues. Perhaps I am wrong.

    When you hacked the firmware...there should have been a specific suboption to enable or not enable clamshell mode... (you can hack it to enable spanning without enabling clamshell, which is what I did, IIRC). Are you sure you selected this option?

    BRILLIANT. Got this from their readme:

    External monitor
    If you use external monitor and want you portable not to sleep with lid closed:
    1) launch SleepLess, check "Prevent sleep with lid closed"
    2) attach external monitor
    3) wait 10 seconds
    4) now you can close lid and work with your external monitor only

    Does this mean i can now have ibook use all its vram on that external display since its own display isnt turned on?

    And also if this works, can i open the lid to let heat dissipate out without the risk of having the ibook display wake up?

    ....... mkrishnan... yeah i did select it. But the thing is, i didnt have a keyboard attached to it.. i used only a usb mouse. And typed on the ibook keyboard. Could it be the problem?
