My 12in Powerbook Never Turns the Monitor Off
Authored by: digitalone on Mar 17, '03 12:47:17AM

My 12in powebook never goes to sleep when the lid is closed. If you don't put it to sleep first, the monitor lights up when you close the lid if it was off. This occurs no matter what, with nothing plugged into it, no airport (I have none yet) nothing, just on battery power. I though this was the normal behavior, but I am starting to think otherwise after seeing these hints.

The keyboard is one piece aluminum anyways with a teflon coating, it can't dissipate more heat than the case. Actually, it's probably less due to the teflon, an extremely poor heat conducter vs. the all aluminum case.

My 12in Powerbook Never Turns the Monitor Off

I am about to buy a 12in powerbook. I was wanting it to be able to be used as a desktop hooked up to an external monitor, keyboard, mouse, scanner, etc... Can this not be done with the powerbook with the lid closed? How do you normally use the machine as a desktop unit when you are not traceling with it?

My 12in Powerbook Never Turns the Monitor Off

Apple states on their support site that you should never operate the powerbook or ibook with the lid closed, but htey don't say why. Probably the heat thing. I'm using an iBook as an internet server and want to let it stay awake while the lid is closed, an also to prevent my 1 year old from banging on the keyboard so I may use the paperclip method.

Here's more info from http://docs.info.apple.com/article.html?artnum=25801 after a search on 'ibook lid' in the Support area:

What might prevent a computer from going to sleep or going into an idle state?

If Apple DVD Player is the active application, the computer will not go to sleep when left idle.

Other applications, such as some fax software, can also prevent the computer from going to sleep regardless of Energy Saver preference settings. Tip: The Mac OS X 10.3 Panther faxing feature does not prevent a computer from going to sleep or entering an idle state.
