iBook (FireWire): Does Not Operate When the Computer Is Closed

Some PowerBook computers are able to operate when the computer is closed and a monitor, mouse and keyboard are connected to them.

Although you can connect a keyboard, mouse and TV or monitor to an iBook (FireWire) computer, it was not designed to operate when closed. If you try to use the iBook (FireWire) computer in this way, the computer will wake up when you connect a USB keyboard, the desktop will show on the external monitor, but it will immediately go back to sleep.
