Sleepless ($5) is a utilty that prevents your Mac from going to sleep without needing to change any system settings. The utility also allows PowerBooks to continue to run with the lid closed, although doing so can lead to heat problems in some units.
I wonder, which PowerBooks would be okay to run with the lid closed, and which ones would NOT be ok? I have a 1.25 Ghz PBG4, and would sometimes prefer to run use a keyboard, mouse, and monitor for certain tasks. Has anyone out there actually tried running your PB with the lid closed?

I've got a TiBook 550 (time for an upgrade? ) and after about a minute of lid closed iTunes playing it just switches right off, no going to sleep, nothing.
Having the lid open is an important part of cooling, especially the Titanium PowerBooks, so I don't suggest it. I'm pretty sure it could damage something...
Maybe it's better in the Aluminium ones?

I've ran my pb a few times with it closed and I'm not sure why you would need a hack. I just plug all my stuff in (monitor, keyboard, mouse), turn on mirror mode then I close the lid of my pb and wake it up from sleep by using my keyboard and mouse. After I get it running while its closed, I usually open it about 20-30� just so it can cool itself off a little better, but I have read in the apple manuel that clamshell mode is not supposed to be detrimental to your computer (im just paranoid and dont want my stupidity to ruin my computer). Im not sure you really need a hack to do what seems to be standard procedure.

Nonsense.
ONLY the Wallstreet PowerBook (1998 PowerBook G3) relied on keyboard cooling. ALL models after that, as well as many before it, allow closed-lid operation, and DO NOT rely on keyboard cooling at all. The thing is, Apple does not support closed-lid operation with no display attached. The ONLY way to do it (the official way) is to attach an external display and keyboard, put the unit to sleep, close the lid, and then wake it with the external keyboard.

Thanks to all that replied. My Powerbook is my first Mac ever, as well as my first notebook ever, so I'm still trying to learn the intricacies of both.

When I have my Powerbook closed, my fan later on will be on the whole time, turning fast and slow, fast and slow, and than I'll get sick of hearing that. So... I don't work with my laptop closed all the way too many times... I'll leave a gap open, maybe 30 degrees or so.

I was also thinking, if I keep the lid closed instead of open just a bit, I'll be saving life on the LCD as well. And my fan runs very quietly in clamshell mode.

Hello,
I sometimes connect my PB to my TV and use it as a DVD player - as I'm sure some of you do. I just bought Apple's BT mouse. Once you run the firmware update, you can use the mouse to wake your computer in closed-lid mode, e.g. when it is connected to the TV. Now, I wanted to play a DVD in closed-lid mode and watch it on my TV, but I am a little concerned of my PowerBook getting very hot and the heat damaging either the screen or the keyboard, or anything else for that matter. Does anyknow if i can play DVDs in closed-lid mode, without a danger of overheating?
Thanks,
BKB.

I would have to go with tooki's post on this one, just scroll up about 6 ot 7 posts and read. I dont get why people have to close their PB all the way n e way, just leave a little open and im sure all will be well.
