TICKET ARCHIVE -> G4 wont Boot-light turns on then off

phaseshifter11 - Mar 27, 2007 - 6:33 pm

I have a Dual 1.42 G4 tower and when I press the on button the power light lights up for one second then straight away fades out. No start up screen, no fans no nothing...

I had just powered down the Mac to install an iogear USB card- then tried to reboot. I've pulled all PCI cards at this point.

I've read some posts of this happeneing before but never heard the outcome.

Please help as this is my work computer.

You can try a "hard" reset by following the instructions for your particular model on Apple's support page. If that doesn't work, I'd worry that your power supply has gone bad (relatively easy fix) or your logic board somehow got damaged (?static electricity) during your USB card install (easy, but very expensive fix). Hope the hard reset works. You can also "zap the PRAM" by holding down command-option-p-r at startup, but it doesn't sound like it even gets that far into booting up.

Hope that helps and please let us know what happens. Thanks.

Thank you Ishan. The hard reset worked using the Cuda button. All is well. Macosx.com rocks!

Great! Glad it worked out. Now just make sure you backup your boot drive

I've been using Super Duper to back up my boot drive. Do you have any other suggestions? I'm also looking for an app to back up my other drives with some music apps that have challenge response codes. Any suggs on that?

Thanks again

Stephen

I like SuperDuper and use it and Retrospect as well. I can't help you with your other backup question, though, although SuperDuper is easily scriptable and you could try that.

Stephen,

You can use SuperDuper to back up all of your drives. I would suggest you have one drive to hold all your backups. Super Duper can make your backup bootable which can be a great life saver.
