Running Powerbook with lid closed *without* monitor

Plug an external mouse or keyboard to your PowerBook. After closing the lid, hit Enter/Return or click the mouse button of whatever to wake it back up. That should work even if no external monitor is connected.

 

Nope. You'll need external keyboard and mouse.

 

Well, you should be able to unplug the mouse/keyboard once it's awake.

 

just keep in mind, an open lid allows much more head to be dissipated than a closed one.... and overheating is bad.

 

Of course there is a way to do it without a keyboard and mouse. All you need to do is use this program: http://binaervarianz.de/projekte/programmieren/kismac/download.php and then go to the sleep tab in the preferences and then check the box that will prevent the computer from sleeping.

It says that it only works while the program is running but if you force quit the program I have found that the sleep prevention setting is still enabled.

By the way it says it only works when the power is connected yet I always use it when the power isn't connected and it still works.

Hope this helps.

 

On my PB I couldn't find any difference most of the time, and even running SETI it had an average of .8 degrees F difference...I would say run it closed.

 

I don't know if this is just an urban myth, but:

When the laptop is closed the heat that normal goes straight from the base of the laptop to the air has to travel through the screen. While it doesn't have a big effect on the heat of the CPU, I've heard that this excessive heat can damage the sensitive components in the LCD screen.

 

I use the KisMac program (as I made a link to earlier in this thread) to run my computer while the lid is closed and I have never had a problem with my LCD screen.

 

The PowerBook is designed to be able to run with the lid closed. It should not damage any components unless Apple has done a major f-up.

The iBook is another matter. I don't know if it's also designed to handle it.

 

I am running a patched kernel (half from other people, half myself) and there is honestly no difference (minus the changes you make). Everything runs just as it has, and your shiny new apple wont seem any different . I dont know any specifics, but I have heard of some people using the loadable kernel modules in order to not tamper with the kernel and still allow them to make their laptops sleep resistant.

Good luck
