Set screen brightness in FireWire target disk mode
Authored by: cmdahler on Jun 29, '04 10:23:19AM

It's possible to start up your PB in target disk mode and then close the lid. The backlight turns off when you do that. The only concern I have about this is heat. The bottom of my PB gets pretty warm after a while with the lid closed in target disk mode, and I know that PB's are engineered to shed some heat through the keyboard. Does anyone know if the fan will automatically come on in target disk mode? I've never heard it start up on mine.

Current powerbooks do not overheat with the lid closed

Current powerbooks do not overheat with the lid closed.

Older models dissipated heat through the keyboard, but the current ones use the bottom of the case as a heat sink instead. This means that you can use it with the lid closed with no problems, as the manual explains.

The only limitation is that it must be plugged in to a keyboard, monitor and power supply - I suspect this allows the machine to be reasonably sure that it's not in a bag. I'm grateful for that, because otherwise there's a risk I might pick up my "turned off" powerbook and put it in my bag where it might well overheat.
