If your MacBook Air doesn’t turn on or start up

Try the following suggestions in order until your computer turns on:

ÂMake sure the power adapter is plugged into the computer and into a functioning power outlet. Be sure to use the 45W MagSafe Power Adapter that came with your MacBook Air. If the power adapter stops charging and you don’t see the indicator light on the power adapter turn on when you plug in the power cord, try unplugging and replugging the power cord to reseat it.

ÂCheck whether the battery needs to be recharged. If the light on the power adapter glows amber, the battery is charging. See “Running Your MacBook Air on Battery Power” on page 34.

ÂIf the problem persists, return the computer to its factory settings by pressing the left Shift key, left Option (alt) key, left Control key, and the power (®) button simultaneously for five seconds.

ÂPress and release the power (®) button and immediately hold down the Command (x), Option, P, and R keys simultaneously until you hear the startup sound a second time. This resets the parameter RAM (PRAM).
