Apologies if this is a FAQ, but is there a modification that one can perform so that when the power fails on a Mac II or IIfx, it will automatically boot up when the power comes back? Standard application is when the power failure occurs on a Mac II running AppleShare. Soldering iron solutions acceptable, as are 3rd-party add-ons (PowerKey?). many thx, Ben Schmidt Bell-Northern Research, Ltd. Ph: (613) 763-3906 Information P.O.

Thanks to the people who e-mailed me notes to use a screw driver and set the power switch to permanently on. Unfortunately, the Mac II (and apparently even the IIfx) don't have anything but a square push button. Apparently Apple learned about the problems caused by this arrangement before they brought out the IIcx and IIci and improved their power switches to work either as push-on/push-off or screw-on/screw-off. Hmmm....I wonder if I could get a replacement IIci power switch and get it installed on a Mac II? I even got a suggestion to tape the soft power switch down. Unfortunately that doesn't work either. When the power is interrupted and then restored to a Mac II with it's power switch taped down, an internal relay clicks at 1 second intervals but the Mac II doesn't power up, unless the tape is removed and the power switch button is allowed to pop back out.

When you press the soft key on the Mac II, power flows from some lithium batteries soldered onto the motherboard to the power-on relay. If you leave the power switch taped down, you will drain the battery, and be unable to start you mac without a costly motherboard modification to replace the batteries! The happened to me due to a broken keyboard where the power button got stuck. -- Jeremy Grodberg "I don't feel witty today. Don't bug me." jgro@lia.com
