SHOOT!

Today, when I went to go start up my Imac G3, and pushed the button, nothing happens. Nothing at all. I've checked the power cable and connection, and made sure it is secure in the back of the computer. Does this mean the computer is totally dead? It was working fine before, but it was asleep when I left it last, and when I came back, the power cord was unplugged. If it died, which I hope not, at least it died in its sleep! :(:( :( :( :

Sorry...it annoys me...

Have you tried resetting the PMU or whatever they call it, should be a good article on Apple somewhere on how to do it.

Would that have symptoms similar to mine?
Yup. If the PRAM battery is dead, the machine won't power on. It doesn't need the PRAM battery to 'jump start' the machine as long as it is only put to sleep. Batteries typically last 3 - 6 years depending on the usage of the machine. Was the machine losing the clock and/or network settings occasionally on shut down and restart, prior to this point?

Of course it could be something entirely different like a blown analog board, but since the battery is a $12 part, it's worth the attempt. I 'think' it is a 1/2 AA 3.6V Lithium cell, but check lowendmac.com for details.

pianodude,


You should not panic and conclude that your Imac G3 is dead.

There could be a variety of reasons why your Mac does not power up. In no particular order:

1. PMU needs to be reset.
2. Power cord and/or adapter not securely plugged into port and outlet.
3. Power cord and/or adapter is broken, and not the computer itself.
4. Other possibilities.


Go to Apple's Support section on their website. Search for help documents pertaining to the non-powering up of a macintosh.

Good luck.

From apple's website:
If your computer does not retain parameter RAM (PRAM) settings when it is turned off, this generally indicates that the battery needs to be changed. Some Macintosh models may display a black screen when you turn them on if the battery needs to be changed.

If you are uncomfortable changing the battery, an Apple Authorized Service Provider can install one for you.
How does this have to do with mine not starting? Wouldnt it start...but just not retain its PMU settings?

The Mac relies on the battery keeping some of the circuits powered, so the soft boot-up process (the front panel switch or keyboard) can take place. If the battery is shot, then there is insufficient juice to initialize the circuits -- and the first casulties are the realtime clock, and then the video circuits (hence the black screen).

But whatever. I'm not here to argue the point with you. Good luck. Bye.

Wow, in less than an hour you've managed to bump this thread about 7 times asking for answers that people have already given you.

The battery is your best bet. It's $12. There are a number of websites that I'm sure Google will lead you to that will help you if the link CanadaRAM gave you doesn't work. Try it, and if it doesn't work let us know.

Or just bring it in to an Apple service provider (or Apple Store) and ask them.
