    Look closely at the screen are you SURE nothing comes up? It may be that the backlight on the display is broken.

Make sure the MagSafe adapter is securely attached to the Macbook and free of debris.

There are two procedures that are advised by Apple to assist in resolving issues where the Macbook chimes at start up, but displays no video.

Here is the first procedure:
Here are some steps you can try to resolve the issue:

• First, hold in your power button for approximately 10 seconds to do a hard shutdown, if you have not already turned your Mac off.

• Once your Mac is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)

• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

• Now, hold the keys down until the computer restarts and you hear the startup sound for the third time.

• Release the keys and allow the Macbook to start up.

Observe to see if your Macbook will boot to the Desk top normally. If it does not, here is the second procedure:
-------------------------------------------------------------------
-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

Update me if you require further assistance.

    Thanks for your advice. Unfortunately, my macbook still gets stuck at the grey intro screen with the apple on it. I tried both of your techniques above. Got any other ideas?

How to reboot a colored apple imac computer


A normal restart only requires you to press the re-start button on the back of the CPU or on the front. You should hear the chime, the screen will come up and you will be taken to the Mac start-up screen (different OS will have different looking screens).
If the Imac has shut down suddenly or prematurely, you might not hear the chime but will see a grey screen with a status bar. Eventually you will see the normal Mac screen and your icons will slowly reappear.
If you do not get any start-up screen or any chime, unplug the unit, remove all peripherals ( such as USB cables etc) and leave it sit overnight. I have restored "dead" Macs by that simple technique.
If you see a screen but the Imac still won't boot, insert the restore disc, hold down the "C" key and restart from the disk. Or use disk warrior and start the same way. Disk Warrior will diagnose and repair problems with your OS.
If none of these strategies work, you may have internal component problems with your Imac that will require more expert repairs.

Mac book pro. Black screen cannot start but with boot sound


Have you tried connecting an external monitor.

A boot chime means the Mac has passed POST, that the screen remains black initially suggests there is a problem getting image to screen which could mean a bad cable to the LCD or the LCD display its self is having problems.

By connecting to an external display you verify the graphics on the logic board is functional, and it could get you up and running till the display problem is fixed.

Also try powering up and when you hear the chime, hold down the COMMAND+OPTION+P+R keys, and keep holding them till the machine has chimed 3 times, this will reset the 'BIOS' in case there is a glitch there stopping the display from showing up.

Damaged 24 iMac screen - want to use ext monitor via "mirroring" in screen preferences, but cannot access system preferernce due to damaged screen...any suggestions


There is an elegant way to solve this, but it requires another compatible model Mac.
Boot the damaged Mac into FireWire Transfer mode by holding down the "T" key immediately after hearing the startup chime. Attach a FireWire cable between the two Macs. Start up the other Mac by holding down the "option" key after hearing the startup chime. Choose the startup drive from the broken Mac. Now your good Mac is booted off the drive of the broken Mac, and any configuration changes you make will be made on the hard drive of the broken Mac.
Attach the external monitor temporarily to the good Mac. Open System Preferences and set the monitors up in mirrored mode. Shut down the good Mac. Then hold the power button in on the broken Mac until the power turns off, and remove the FireWire cable.
Now move the external monitor to the broken Mac and boot it. It should come up in mirrored mode.

The screen on my Mac Book white 13.3" stopped working. it chimes on but nothing to the screen?


Power it off. Hold down the power button. We need it to not show any white light on the front right.

Press Power and HOLD DOWN these 4 keys until you hear 3 Chimes.
ALT+COMMAND+P+R.

That will restore the PRAM (bios to PC users) to factory settings. If that fails then a trip to the Apple store will be in order.

WHAT TO DO WHEN YOUR MAC BOOK PRO FROZEN AT THE START UP SCREEN ???


Get your Mac OS DVD out, restart the machine with the disk in your optical drive, and after you hear the famous mac chime, press and hold the C key while it starts. When you reach the install window, don't install but rather open the Disk Utilities App and run a verify of your hard disk, also repair permissions. Then restart as normal. This should get you back to operation.

When I start up my G4 I doesn't get past the white logo screen with the circular icon spinning. Have removed battery and depressed start up button until a loud beep occurs but still nothing


I had a problem with my hard discs. That's where I got, but my screen froze after a few minutes. try pressing apple + s after the chime. See if you can search around there. Also, try holding the shift key when you hear the chime, or when booting if you don't normally hear the chime, and hold it 'till you see the apple logo.
