Q: iMac late2006 17". When power button pressed, white light comes on and stays on but nothing else happens?

As stated: our Mac won't turn on other than the white light on the bottom right.

Read through the support page which suggests taking the back off ( and use internal power switch) as in owners manual section 4, however it's not in there. At the bottom there is a couple of screws and a couple of star head screws, I'm guessing I need to undo these and possibly pull from the bottom. Don't want to break it,

Thanks

A steady LED light generally indicates that the computer is on and the display is asleep.

Before you get inpatient and start taking out screws or trying to open it up, which is not an easy task on that model.

Reset the SMC, as per > Resetting the System Management Controller (SMC)

1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.

Then run the AHT, as per > Using Apple Hardware Test
