Question about Computers & Internet
MacBook Air will not power up at all It should be fully charged
Posted by Anonymous on
Make sure that your power supply is working. The light on the head should be green or amber.
If you borrow another power adaptor, make sure it is the correct wattage for your unit.

Go to your system preference panel in the dock... click on the sound control icon. Look down at the bottom of the dialog box... there is a "MUTE" check box....make sure it's unchecked....
Also press the 'fn' key at the bottom left of your keyboard while pressing the f5 key... to raise volume...
let me know if that solves the silence!

This is a known issue with some of the Macbook Airs - you should bring the machine to an Apple store, or open a case at apple.com
They may be able to repair/replace at no cost, depending on how old the machine is.
Hope this helps, and good luck!

You could try plugging in machine and ensure battery is charged.
Press and hold the power button for about 20 seconds.
also the other thing is to immediately after you press the power button.
hold these 4 keys at same time continuously - cmd, alt, P, R
hopefully machine will power up and down and up again if you keep holding them.

3 x beeps means there is a problem with the memory, either it needs reseating, replacing or a problem with the slots on the logic board.
