Mysterious Hardware Problem (I assume)

[MacKenzie999]

Hey folks...

A weird thing happened to my system over the weekend.

I had powered it down so that I could physically move my mac. At one point I plugged a USB cable from my printer (HP Deskjet) to my mac, and the mac powered up by itself.

When I went to use the mac, it would not respond to the keyboard nor either of two optical mice (the mice did not light up like they typically do when powered up by the system, and the caplock button on the keyboard did not light up when pressed either). I have two usb ports on the mac and swapping them made no difference.

It gets worse...

I powered down the system and later on when I went to check it (you know, in case little helper gnomes came and fixed it while I wasn't looking) and now it will not power up at all. The blue power up button will light and throb for as long as I hold it, but no power up.

Any recommendations or suggestions are greatly appreciated.

G4/466, osX.1.5

Thanks!

It's a USB/electricity issue. I've had this happen with the MacAlly iMedia keyboard. Turn off the computer before bed. Turn off the light, the computer turns on. Turn off the computer, exchange the keyboard, go to sleep .

Try using certain combinations of USB devices and hubs, you'll find the offender, but it's not the computer most likely. If need be, work with one USB device at a time and use a cable you know is working.

The mac was still plugged in, just powered down. I was hopeful when several people suggested simply disconnecting all peripherals should clear up the problem, but sadly still no power up. This problem combined with the likely new macs being announced today certainly presents a conundrum...
