(mac) How to disable sleep mode


Recommended Posts

I'm wondering how to disable sleep mode on a PowerBook G4 so it won't go under sleep mode when the lid is closed.

Also I'd like to know if QuickTime has a function like WMP which will disable screensaver when movie is playing

You can get a kernel hack to do this in Jaguar, I dunno about Panther. However, it is *HIGHLY* not recommended because it will more than likely overheat things and cause permanent damage. It goes to sleep for a reason, ya know :p

Back to the first question. With newer PowerBooks (since the Pismo, like mine), close the lid, putting the PB into sleep mode. Then plug in a USB keyboard (mine seems to work with my Logitech USB trackball as well). This will wake it back up and you can then use it with the lid closed.

Of course, I dunno if I'd recommend doing it :p

I do this all the time with my 12" powerbook. I hook it up to an external 21" monitor, keyboard and mouse when I am working on anything design intensive. I really appreciate and almost find necessary the extra screen real estate at times. This has never caused my powerbook to heat up beyond normal temperature. However, if it ever did and something was damaged, it would take me all of two seconds to get on the phone with Apple and #1 chew them out for suggesting me to do something damaging to my machine and #2 demanding a new replacement or free maintenance on my current one.

Actually, you can work with the lid closed on a powebook when using the external display. Just move any human interface USB device attached to it, like the keyboard.

It will not overheat if it's a powerbook. An iBook _will_ overhead since it dissipates heat mostly from the keyboard, therefore would be nasty to the LCD.

There's a huge advantage to this: When in clamshell mode, all video card memory is allocated to the external monitor. If the powerbook is not in clamshell mode, and monitor spanning is on, each monitor is using half the videocards memory.

well, if you're so worried about the whole overheat b/c the lid is closed problem, I've got mine using just an external monitor while it is open. I started out w/ my keyboard, moust and external monitor connected. I then closed the lid, clicked the mouse to go to the external monitor. All is well at this point. The video is out to the external monitor. Next, i opened the lid, bam - the video stays only on the external screen. 10.3.2
