Hi, I have just recently decided to change my old iMac style keyboard for the new Apple Pro Keyboard. Ever since then when I go to shutdown the computer, it appears to shutdown and then it restarts again. I thought maybe I hit a key by accident but I have tried it several times. My only options at the moment are to pull the mains plug out or go back to the older style keyboard, which I don't want to do. Anyone have any ideas? Keep in mind this is a G4 Tower (PC Yikes) and not a cube. If anyone knows why can they contact me via email (nahaz@idx.com.au) as soon as possible. Thanks for any help forthcoming...... Nigel Hunt

Are you sure its the keyboard ? On the AGP G4, the keyboard cannot even start up the computer. Have you tested it with the old keyboard, & with no keyboard at all ? If it still does it, then its a motherboard fault. cheers Andrew Nigel Hunt wrote: > Hi, > > I have just recently decided to change my old iMac style keyboard for the > new Apple Pro Keyboard.

I do have a Imation Super Disk Drive installed in the USB port of the keyboard. I am just wondering if this could be it? I will try and verify it tonight.

Hi, From what I understand, USB peripherals, especially if they have an additional power supply, can release some voltage over the USB-port on powering down the computer. This residual charge is then interpreted by the computer to be the power-on signal, and the machine does so accordingly. This is covered in the FAQ section of the apple TIL.(http://til.info.apple.com/) Hope this helps Hans

When I disconnect the USB cable the computer shuts down fine. With it installed it restarts the computer. What a bummer!!! I tried looking for it in the FAQ section but never found it. Obviously I never read it as deeply as you did. Thanks heaps..........
