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:

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.

My numeral key are not working[123456789 right side of key bord]


Step 1:
On some laptops it may be difficult to locate and activate the "Num Lock" key. Depending on the laptop, it may be hidden as a function where you have to press two keys. Most of the time, a laptop keyboard is just like a full desktop computer keyboard and it has a "Num Lock" key on it. Most people do not realize the "Num Lock" key is on their laptop keyboard because it barely serves a purpose without a full numeric keypad.

Press the "Num Lock" key on the laptop at the top, right of the keyboard. Press the "Num Lock" key and the "Fn" key simultaneously if the above does not work. Press "Fn" and "F11" simultaneously on the keyboard to activate the "Num Lock" function. Some laptops, like Toshiba, do have a "Num Lock" key. The shortcut for G3 Mac laptops it is "F5," and on G4 Mac laptops it is "F6."

Laptop sceen light& dark


Locate the Fn (Function) key on your keyboard. It may be on the bottom left side with dark blue letters. Locate the two "brightness" keys near the top of the keyboard. These will be in the "F" keys, possibly if F6 and F7. They should have little sun pictures or something similar to indicate brightness. Hold down the Fn key while pressing F7, or whichever "F" key your laptop uses to increase brightness. Tap F7 repeatedly until you reach the desired brightness. Fn must be held down as you continue to tap. Hope this helps.

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.

Acer aspirw 5100 brightness


1.The Function key (Fn), and the F6 key are pressed to turn the Backlight off to conserve power.

2.The Fn key and the right side arrow key, are pressed to increase Brightness.

You have a TFT LCD monitor screen. (Thin Film Transistor)
The LCD screen cannot be seen clearly without a Backlight.

The Backlight is a CCFL. Cold Cathode Fluorescent
tube. Resembles a small fluorescent tube used in residential, and commercial lighting.

The Backlight can go bad after time, and weaken.
If so, it will have to be replaced.

Sounds easy, it isn't.

The TFT LCD monitor screen is made up of layers. It's enclosed in a thin metal frame. Resembles a picture frame.

The frame is removed, after removing the LCD screen from the laptop's top cover.

The LCD screen transparent outside layers, are separated partially from the rest of the LCD screen.
The Backlight is removed out of the side.

This gives you an example of removing, and replacing an average Backlight,

How do I turn on my backlit keyboard on my dell with windows vista?


Hi,

Sorry for the last answer. The expert probably didn't understand your question.

If you have purchased the optional backlit keyboard, the right-arrow key will have the backlit keyboard icon on it. The backlit keyboard provides visibility in dark environments by illuminating all symbols on the keys. The settings for this keyboard can be personalized by using
Dell QuickSet.

Backlit Keyboard Brightness Settings – Press <Fn> + right-arrow key to toggle between the three lighting states (in the given order).
The three lighting states are:
a. full keyboard/touch pad brightness
b. half keyboard/touch pad brightness
c. no lighting

Hope this helps. If you need the manual for this computer, it is located here:

Thanks for using FixYa.

Your screen sounds fine, most likely just your backlight going out, either that or you could have hit the key for using an external monitor (function f6 is the LCD/external monitor switch for my computer). I'd look into the function f6 and play around with that, if not you can just buy a new backlight from ebay or an internet supplier.
