How old is the PRAM battery? If you have never changed it since you bought the computer, be aware that they last from three to five years. A dead battery will prevent the computer from starting.

And if the battery is new then follow steps below and ur problem will be solved..

Reset PMU (Power Manager Unit).

1. Disconnect all cables except the power cord.
2. Touch any metal surface to ground yourself, disconnect the power cord, and open the computer.
3. Find the PMU reset button and push it. once only. It's a tiny, tiny button, probably unlabeled, located on the motherboard and probably near the battery.
4. Close the computer, reconnect everything, and give it a try.

If this doesn't work, replace the battery. BTW, if you have a power strip, that doesn't necessarily mean that it gives surge protection. Get a good surge protector/battery backup.

Please Don't forget to rate me as fixya..

Desktop background doesn't show

I get this too. (Love using the solid blue background)

1. Check if there are any other users logged in on the Mac.
2. Log off all the users including yourself
3. Log in only on your user account and change the background

If that doesn't work, restart first and repeat.

If even that doesn't work, change to another solid background first and then change it back to the picture.

Cant print using Dell A920 printer on my imac. printer set up shows driver is correct I think and the printer name is correct.

So clearly the Macintosh sees and recognizes the printer. WIll it let you queue a document to the printer? After you do, you will see an extra icon on the Dock that represents the printer queue. Open it up and see what is happening to the printer job. If it disappears, it was sent to the printer and the Mac thinks it was printer successfully; if it isn't printed then you have either a bad printer or a bad printer driver. If it stays in the queue and goes to "hold" state, look in the log to see what the error was -- the Mac is unable to negotiate with the printer to get your file printed.

Mac mini display problem

Sounds like your monitor is not set right. Is the monitor LCD or CRT type? You can open system preferences from the top of the screen under the apple icon. Try and see if you can adjust the resolution settings. Also if you have an LCD screen set to "auto" adjust to reset the screen. Good Luck.

Mac Mini G4 turns itself ON

Have you looked into System Preferences>energy saver>schedule? Maybe it's set up to start itself. I have my mother's mac set to start up and shut down automatically. Just a thought.
