Firstly, connect an external screen to the DVI connector on the right-hand side of the laptop. This will determine if the graphics processor is functioning.
If the external screen functions correctly, then the problem is in the laptop display.
If this is the case, shine a torch at the screen to see if the desktop is visible. Failure of the backlight will cause the screen to appear dark but the desktop is still displayed very dimly.
If you can't see the desktop with the torch, then the screen is at fault and will need replacing.

SOURCE: my macbook pro starts up but i dont get the chime

Most likely fix is to reset the SMC.
Turn the power off, remove all peripheral cables, connect the AC power supply. Using the left-side keys, press the combination Shift-Control-Option-powerbutton ONCE. The LED on the MagSafe connector
should go off, go back to green when keys are released, and may change to orange if the battery still needs some charge. Wait five seconds, then press the power button to restart the computer.

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.

I dropped my macbook pro. No external damage but it won't turn on. It will charge.


Try these steps. They're worth a shot and the worst that will happen is that it still will not start up:

  1. Press the control key, the command key, and the power button simultaneously and hold for three seconds to try to restart the computer.
  2. 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.
  3. Reset the SMC for the 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.
  4. If these steps still don't help you get it going, there is a chance that the hard drive sustained too many G's on impact. This sounds worse than it is because a new hard drive is relatively inexspensive for your machine nowdays. The downside is that the amount of G's it sustained can be measured by a tech. That means that Apple Care will probably ask you to pay for it. This is all assuming that the hard drive is the issue.
  5. *** Don't just give up on getting some of your files back if it is the hard drive. There are several ways to recover info from a damaged hard disk. I hope this helps you and good luck! Don't forget to vote if this was helpful :)

Reset the PRAM first. Hold down Control+Command+P+R when booting up before the chime. Let it chime three times and let go.

Warning bell won't stop sounding


Section 13-09: Gauges, Warning Devices — Chime System 1996 Windstar Workshop Manual
DESCRIPTION AND OPERATION Warning Chime Systems Three distinct sounds are used to indicate the area of concern. Seat belt warning generates 1 chime per second
key-in-ignition generates 2 chimes per second
headlight on generates 4 chimes per second.
Key-In-Ignition Warning The key-in-ignition warning will sound when the driver's front door (20125) is opened with the key in the ignition switch. It will continue to sound until the key is removed, the front door is closed, the ignition switch is turned to START or the vehicle speed is over 24 kmh (15 mph).

Safety Belt Warning When the ignition switch is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.
  • The safety belt warning indicator lamp (10C859) will activate for 60 seconds or until the driver's safety belt is fastened. Both the chime and lamp activate at the same time.
Anytime the ignition switch is released from START and returns to RUN while the safety belt lamp or chime is activated, the safety belt warning lamp or chime will remain activated until either the timing sequence has been executed, or the safety belt is buckled.

Headlamp Switch On Warning The chime will be activated if the headlamps or parking lamps are ON, the key is not in the ignition and the driver's door is opened. The chime will sound at a rate of four per second.
