Question about Apple MacBook Pro Notebook

Mac laptop displays minimum brightness

My mac laptop display defaults[?] to minimum brightness (nearly black screen) at start up.  This problem is random, as far as I can determine.
Shining a bright light on the screen allows for mouse pointer tracking, which then allows for the following fix: System Preferences > Display > Maximum Brightness.

Why does my mac laptop randomly start up with a dark screen?

    Thanks, I think I fixed the problem by changing the System Settings to not dim the screen to minimum brightness after five minutes (or when there's low battery power).  I set these for three hours, added a screen saver option, & haven't had the problem since.

Check to see if there is a box right below that... Saying something along the lines of readjust to brightness of surroundings, etc!  Make sure box is unchecked for you, in regrds to your issue and then see if that helps!  I will look a little further into it for you!  Let me know if that helps though!

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.

Screen dim lighten


On your Mac...

Click on the Apple icon at the top left of your screen.
Then select System Preferences.
Then select the DISPLAYS icon.

In the displays window, you will should see a Brightness slide bar. Make sure that slider bar is all the way to the right. The the slider bar is already to the right side, then it might be a hardware issue with your Mac. =(

How do I adjust brightness and contrast


On a MacBook try hitting F1 and F2. You'll notice they have small little icons to signify less bring and more bright.
Also doable via the display Preferences (Apple Icon top left, Preferences, Display).

Display is too Dark to work with but brightness lever up to max.


Apparently the backlight for your display is failing. You'll most likely have to have the top half of the macbook replaced per Apple usual service standards.

The screen on my apple ibook laptop is black, whats wrong with it?


First make sure your screen brightness is not turned down. If not, and the computer can still turn on, chances are it's the logic board or display that has gone out. Your computer will need to be repaired by a specialist.

Laptop will not display screen although is turned on.....


I assume you are saying the screen is totally black, not blue. If it is totally black there can be a large number of causes. It is hard to give one simple answer. It could relate to the brighteness of the screen, the display, the logic board, the graphics card or even a problem relating to updating Apple firmware, You could try some simple things first.1) If the lighting on your computer is accidentally turned all the way down, your screen will be black! To turn the brighteness up, push F2 on the top of your keyboard and click until the lighting improves and you see the screen. If your display stays black it could be an indication that you just need a new Display. They do wear out. 2) Another thing to try is to start the computer in Safe mode. http://support.apple.com/kb/HT1564?viewlocale=en_US As you push the power button hold the shift key down. This can sometimes help resolve issues relating to startups. Also, if your screen stops being black it is an indication there is nothing wrong with your display. 3) You could try resetting the PRAM http://support.apple.com/kb/ht1379, This can also help with a startup issue. 4) Some specific models of Macbook Pro computors have issues caused by the NVIDIA graphics card, which Apple knows about and apparently will repair, possibly free of charge. My suggestion if none of this helps is to take it to a Genius bar at an Apple store for them to troubleshoot. That, in itself, costs nothing. Other suggestion search with google for further answers from other Mac owners!

The screen suddenly went black while connected to an electrical outlet. Nothing works.


Three immediate possibilities in order of expense:
1) Make sure the brightness is on. Press the F2 key.
2) Screen backlight could be blown out, especially if you can hear the disk seeking, fans, etc. even though the screen is black. Connect your Mac to an external display or TV using the appropriate adapters. If you get an image, you need a new backlight or LCD panel.
3) Entire machine is plotz, especially if you hear absolutely no chimes, disk movement, optical reset, fans, etc. This may indicate a power board or logic board issue.

Random Flashes on Macbook 13" native screen


you could try reseting the pram. this is accomplished by holding down Command, Option, P, and R at startup you will want to hear the start up tones at least three times. if that doesnt work you might have an inverter issue, the inverter is located behind the screen and needs to be looked at by a pro
