How to turn off laptop screen when connected to Monitor

[Punkyclown]

Hi All,

I have connected my Powerbook 1400c to an Apple 15" Multisync AV Monitor. Runs well,
but I can't close the laptop without turning off the Monitor also. Is there some setting I can
user to do that? Much appreciated.

Is your Powerbook running on battery or connected to the mains? Current laptops have to be connected to run in "Clamshell" mode.

Connect a display to your Mac - Apple Support

Mac computers support one or more external displays, depending on the Mac model. Here's how to connect an external display.

Hi,

I don't recall the older PowerBooks supporting closed-lid mode. They would simply go to sleep when the display was closed.

Perhaps I am missing something but if you want to operate or see anything on the the monitor surely the laptop needs to be open so that you can use the keyboard. The monitor, of itself, cannot make inputs to your laptop nor can it take in any (picture) data unless it is connected to another computer or video source.

Or, like I do, you use a Bluetooth mouse and keyboard.
