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 laptop has suddenly frozen, i turned it off by the power button and whenever i try to turn it on it turns white screen, then shutsoff after 3-5minutes.


Resolution
  1. Disconnect any devices connected to the computer including printers, hubs, and third-party keyboards or mice, and test the computer again by trying to turn it on.
  2. If you're using a MacBook or MacBook Pro, check the battery level. Press the small button on the battery or on the side of the computer. You should see lights indicating the battery's level of charge. If you see just one light blinking, the battery needs to be recharged. Use the computer with the adapter connected to recharge the battery.
  3. Unplug the power adapter from the electrical outlet and from the MacBook, MacBook Air, or MacBook Pro. Wait one minute. Plug it back into the wall first, then to the computer. Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the power adapter LEDs should light up green or amber.
  4. Inspect the MagSafe port on the computer for debris, such as metal stuck to the magnet in the port, which might prevent the connector from seating properly. On the adapter side, look at the DC connector for dust or other debris and check whether pins are missing, bent, or stuck down. If you find any of these to be true, see Apple Portables: Troubleshooting MagSafe adapters for instructions on cleaning the adapter.
  5. Make sure you are using the adapter that was designed for your computer. If you aren't sure or if you need a new adapter, learn which adapter is appropriate for your computer.
  6. Press the control key, the command key, and the power button simultaneously and hold for three seconds to try to restart the computer.
  7. Reset the PRAM. After pressing the power button, hold down these keys simultaneously: Command-Option-P-R, until you hear the startup chime at least one additional time after the initial startup chime.
  8. Reset the SMC for the MacBook And MacBook Pro by removing the AC power, removing the battery and then holding down the power button for five seconds. On the MacBook Air, press (left) Shift-Control-Option along with the power button once. Note: You must use the keys on the left side of the MacBook Air keyboard.
  9. If you recently installed additional memory, make sure it is correctly installed and is compatible with your computer. Remove the new memory to see if the computer starts up properly without it.
Also:
The MacBook SMC Firmware Update v1.1 improves the MacBook's internal monitoring system and addresses issues with unexpected shutdowns. This update is recommended for all MacBook systems, including those that received warranty repair.
You can use the Software Update feature of System Preferences, or download the MacBook SMC Firmware Update v1.1 from Apple Software Downloads.
Note: If your MacBook is running Mac OS X 10.4.6, you won't be able to see the SMC Update until you update to Mac OS X 10.4.8. Once you have updated your system software, the SMC Update will appear as an option in Software Updates.
MacBooks running Mac OS X 10.4.7 will be able to download and install the SMC Update, so it is not essential that you update your system software, although Apple always recommends updating to the latest version of the system software.
If your MacBook is in a state where it will not remain on long enough to install the update, wait for the issue to reproduce itself. Once the MacBook has turned itself off, turn the computer on by holding the power button down. Keep the button down until you hear a single long tone. Once you hear the tone you can release the button, install the recommended updates, and restart normally.

Try to charge it with different Apple charger. If your PC is under warrenty then you could call Apple Costomer Service and have them send you a new charger. The number is 1-800-676-2775.

My MacBook don't start. Is the power button? Is any password to solve this?


A password would not prevent your Macbook from starting, so I don't think that is the issue.

There are several variables to consider when it comes to power issues with an Apple Macbook.
For one, is your battery charged where you can test it without the MagSafe adapter, to see if the Macbook will start up?
• Also, is the MagSafe Adapter itself, not frayed or damaged, is free of debris and is able to connect securely to your Macbook?

If you have checked both of these sources for powering up your Macbook and you still cannot turn your Macbook on, then that is a hardware issue.

Sources of hardware issues with your model of Apple portable notebooks are:
* The Power supply: (source of power to the main logic board in the Macbook, and connects to the MagSafe port which of course connects the MagSafe adapter into a external power source - i.e: "a wall power socket")

* The Main Logic board: the main board in your Macbook which contains all processors, RAM, audio & video ports, ethernet, USB and other ports and components-including the Power Supply.

* RAM- If your RAM (Memory) goes bad, this can also impact the start up of your Macbook
---------------------------------------------------------------------
A good way to test and see if you can start your Macbook up is to try this procedure below:

-SMC RESET-
The System Management Controller is an integrated circuit (computer chip) that is usually on the logic board of your Mac computer.

It is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

• If the computer is on, turn it off.
• Disconnect the AC adapter and remove the
computer's battery.

• Press and hold the power button for 5 seconds
and then release the button.

• Reconnect the battery and AC Adapter.

• Press the power button to restart the computer

**IF you cannot get you Macbook powered up using this SMC Reset, that means you will need to take your Macbook in to your local Apple retail store Genius bar or Apple-authorized service center to have a diagnostics performed on your Macbook.

I am sure this will help guide you in the right direction toward address this issue.
Let me know if you have more questions regarding this issue.

Thanks!

Macbook will not power on. It's not the battery according to the Genius bar technicians


I assume it doesn't power on from the AC adapter either?
If not, perform the following steps:
  1. Disconnect the AC adapter and remove the computer's battery.
  2. Press and hold the power button for 5 seconds and then release the button.
  3. Reconnect the battery and AC Adapter.
  4. Press the power button to restart the computer.
If it doesn't restart, you have logic board issues, and need to bring the machine in to a service tech.
