External Power Button for G5

Message #1 - Posted 2004/08/19 - Roch M. Comeau

Hello,

This is a bit of a long-shot post, but here goes...

I recently purchased a new Cinema display and found that the power button can not be used to turn the computer on (in contrast to Apple monitors and keyboards dating back to 1986 or so).

I put G5s inside a custom computer cart and have relied on the power button on the Cinema Display to turn on the computer+screen without opening the cart, so this new "feature" is quite a departure from Apple and a big pain for me.

After inspecting the inside of the G5 I found that the power button has 3 short wires soldered to it which is plugged into a small circuit board with a 3 pin connector. I don't recognise the connector brand or part number, so I can't get these connectors to make a Y splitter which would allow me to put a second power button in parallel outside the cart.

My questions are: Has anyone looked at this 3 pin connector and figured out what it is (so one could order them at an electronics supplier). Otherwise, has anyone else built an external power button somehow?

Thanks for any advice.

Sincerely,

Roch Comeau

Just for historical interest, power on the keyboard showed up in 1987. Power from monitors was _much_ later. More than a decade, easily. Keyboard power went away because making it happen over USB was a Bad Thing.
Monitor power, I'm surprised to hear has gone.

I think the obvious question is: How often do you power down? Followed by: How often do you need to power down?

Standard output is like your butt. Everyone has one. When using a bathroom, they all default to going into a toilet. However, a person can redirect his "standard output" to somewhere else, if he so chooses. - Jeremy Nixon

Our company manufactures scientific equipment that sits in a mobile cart. The cart may be moved from room to room, or even around the lab which might require it being powered down to move a plug. Suffice to say, it is not a desktop machine, nor something sitting on an equipment rack. Up until now the G5 (and Macs back to 1987) had a nice feature with the soft power switch on either the keyboard or the monitor (I thought they moved from the keyboard to the monitor to increase Apple monitor sales). Now, I wish it would at least have a "hard" switch like many PCs have so I could leave it on inside the cart, and rely on the mains power switch on the cart (which is connected to an internal power bar) to power up the computer.

Anyway, I want and need the remote power switch. All I need is the connector specs if someone by chance has it.

Thanks,

Roch

And it wasn't universally available even then.

For instance, the LC systems all had mechanical power switches.

There are no concrete rules with Macs...
