If you can’t eject a floppy disk

If you can’t eject a floppy disk in the usual way, try the following in order:

mHold down the x and Shift keys and press the number 1 key on your keyboard to eject a disk in the internal disk drive.

mTurn off the computer. If the disk isn’t ejected, then hold down the button on your mouse or other pointing device while you turn the computer on again.

mLocate the small hole near the disk drive’s opening, and carefully insert the end of a large straightened paper clip into it. Push gently until the disk is ejected. Do not use excessive force.

If nothing works, take the computer or disk drive to your Apple-authorized service provider to have the disk removed.

Power supply

The power supply in your computer is a high-voltage component and should not be opened for any reason, even when the computer is off. If the power supply needs service, contact your Apple-authorized dealer or service provider.
