Macbook Pro Black Screen but Keyboard LED On


If you've already tried turning up the brightness of the screen (the "sun" icon), then you may have a problem with the backlight (possibly burnt out, in which case you'd need a new backlight bulb). See this post for more details:

How do I Return regular keyboard functionality on Apple MacBook Air notebook


Sounds like you need a new keyboard. You can get one from apple or a third party vendor. One thing you might try is re-installing the drivers for the keyboard.

The picture is very dark and want to brighten it


If your keyboard doesn't have a brightness control button (mine is F6), open System Preferences and click on the Displays control panel. Move the brightness slider to the right to increase brightness. If you don't want the computer to automatically adjust brightness uncheck the box next to Automatically adjust brightness as ambient light changes.

The letters on my keyboard doesn't work


Dust the keyboard to remove any debris.
If that doesn't work, re-seat the keyboard. This requires disassembling much of the laptop. www.ifixit.com has great guides on how to complete this for every model of mac laptop.

otherwise try:
Resetting the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons

Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:

* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc

* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc

* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc

* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc

* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc

So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery

This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini

Resetting SMC is different for non-portable Macs:

Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

Happy New Year,
Kerry

Hi, I have an Ibook G4 and i have a problem with my backlighting, it is very dim hardly visable. Is there any free solutions ?


F1 and F2 on the keyboard make the backlight go dim or get brighter. connect an external display to the computer if the issue doesn't show up on the external display it's the LCD inverter board that will need to be replaced.

Typing numbers instead of letters


Sounds like you may just have your numlock on. Just press function key plus F6 (on a macboook) and the numlock is off. If not you may have a broken keyboard. You can try to replace the keyboard yourself using an Apple Tablet Repair Guide or send it to a third party service Apple Tablet Repair.

Can I add backlight to my 13 inch macbook (unibody)?


Do you mean the behind the keyboard backlight or something else?
As far as I'm aware only the macbook Pro models have KB backlighting so without a motherboard change you are probably out of luck

Screen is dark or dead on my 17" Macbook Pro


This could be a backlight issue, a board issue or an inverter issue. Look at the screen closely, if there is a faint image it's either a backlight issue or inverter issue. To weed out between the two you can just order on inverter, they're 20 bucks on ebay, if that doesn't work, replace the backlight. Backlight repairs are somewhat difficult. As much as I would like to be able to tell you a quickfix that will solve backlight the problem, you'll most likely have to google for guides that show you exactly how to replace the backlight or bring it in for repairs.I work for Mac Repair NYC and i have to fix this problem a lot.

REplacing the keyboard on this model requires removing the top case, disconnecting the ribbon cable from the logic board and extracting the keyboard from the top case. Make sure you remove the battery from the computer first. You will need a jeweler's phillips and a torx 6 for the top left and right torx. It will require for you to peel back the mylar and backlight cabling ( if your Aluminum has a backlight keyboard )

Before doing this thought, i would try resetting the PRAM and NVRAM.

Keep me posted if you have more questions on this.
