Run newer PowerBooks with the lid closed
I've been doing this for quite a while with my G3/600 iBook (16 VRAM) to no ill-effect; You just need to use your common sense! I typically place a quarter or some other coin below the end key, and turn the screen brightness to zero (i.e., no backlight) before closing the lid. I routinely drive around with the closed iBook on the passenger seat of my car with a line-out from the headphone jack to my car's deck. The notebook barely even gets warm. My iBook has a fan which kicks in when the processor is running far too hot. This happens very rarely it seems, and only when the processor is allowed to run full-tilt, as specified in the Energy Saver system pref panel. For lid-closed, non-processor intensive activities like playing music, I simply set the processor performance to low. The fan has never come on in my lid-closed operation. As noted above, the left-hand palm rest (where the processor is located) barely even gets warm! Certainily, with a little common sense, you can surmise that this isn't anymore detrimental than resting the notebook on your lap, where no air is allowed to circulate underneath the casing. Actually, here's another bit of advice if you're using your notebook as an overgrown iPod: If you carefully place the mouse cursor over the "next track" button in the iTunes window before you close the lid, you can gently press down on the edge opposite the hinge to "click" the mouse button underneath the trackpad. This lets you select the next track in iTunes -- especially useful if you're doing a shuffle-play with the lid closed, and want to skip a song.

Thanks for this amazing tip. It works great for me (Ibook 800 mhz combo). |
