I need more info on which model Macbook air you have. You can try to reset the smc and pram https://discussions.apple.com/docs/DOC-3604
but three beeps is often memory related
http://support.apple.com/kb/HT5860?viewlocale=en_US .
Depends on the model you have whether or not the RAM is removable.

The bios on the machine hardware has failed to book.
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.

SOURCE: beeping before booting

probably the RAM. Take it out and put it back in to check. You will need some RAM to boot, so try each stick separately if you can. I'm guessing though that you'll have to get at least one other stick of RAM to check. You'll probably find that one is bad. It's probably covered for life, but that would be a good reason to upgrade it.

SOURCE: My macbook won't turn on. Instead the screen stays

Tones before the Happy Mac or Apple logo means that during the start up process (when Mac checks Hardware) it found something wrong. I have seen this with bad memory, and crashed Hard Drives.
Insert the original CD that come with the machine and hold down the C key and then hit the power button.
Then try to reinstall operating system.
All your data will be there. You may need to enter program serial numbers again but Music. Docs etc should still be there.

SOURCE: MacBook Air 11" won't power

1. Verify AC power presence with MagSafe LED indicating on or charge state.
2. Verify battery as being partly charged, with orange/amber LED on MagSafe power connector.
3. Reset SMC
Resetting the System Management Controller (SMC) The System Management Controller (SMC) is a chip on the logic board that controls all power functions. If the computer is experiencing any power issue, such as not starting up, not displaying video, sleep issues, or fan noise issues, resetting SMC may resolve it. To reset SMC: 1. If computer is on, turn it off by choosing Shut Down from the Apple menu. 2. Connect power adapter to computer and to a working power source. 3. On built-in keyboard, press (left-side) Shift-Control-Option along with power button just once. Important: Use Shift-Control-Option keys on left side of keyboard. Note: When the LED on the MagSafe connector is orange/amber, resetting the SMC will change it to green for a few seconds, indicating that SMC was correctly reset. 4. Wait 5 seconds and press power button to start computer. Note: If bottom case is removed, you can alternately reset SMC by disconnecting both power adapter and main battery, and holding down power button for 5 seconds.

Power Adapter Issues 1. Connect AC adapter's MagSafe connector to the computer. The LED on the connector should be green or orange/amber. 2. Verify power cord or duckhead is firmly attached to AC adapter. Check that duckhead is not damaged. 3. Verify AC power source is supplying AC power. 4. Check for dirty or stuck pins on the MagSafe connectors, both on the adapter and the computer. 5. Reset SMC by pressing the (left) Shift-ControlOption(Alt) keys along with the power button once.

My MacBook won't turn on!!!


If it is repeatedly beeping it sounds like a memory issue. you should try removing your memory one stick at a time and attempting to reboot.(remove one try to start, replace, remove other try to start). If it doesn't work with either stick try using a "known to be good" or new stick of memory and see if it starts. Here is a link explaining how to remove and change/upgrade your memory. Very simple really, involves removing the battery and removing a plate with three screws in it.

When I turn my MacBook air on a blank White screen


Leave the Macbook air turned on until the battery goes dead. Then Connect to power and start it up. That should solve the problem. You problem was caused by not letting an update install in full.

There is no display on the laptop and it does three short beeps three long beeps and three more short beeps


The video card or onboard video is dead. That is what that beep code is telling you. More than likely you will need it replaced. Sorry.
