It's hard to find a Compaq manual their site, but they indicate you'll find this in the help files on your computer.
This is usually done with a combination of keys-look for the Fn key and a key that looks like a sun symbol. It may have an arrow pointing up or down. Use these keys together to change the brightness.

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).

How to adjust contrast on dell 610


From this web site:
http://www.computerhope.com/issues/ch000594.htm
How do I adjust my brightness or contrast on my laptop? Every laptop is different, so adjusting the brightness or contrast on your laptop may vary from the steps provided on this page. However, understanding the process of how to adjust the brightness or contrast will help you change your settings.
Most laptops adjust their brightness and other settings using the function key in conjunction with another key. For example, pressing and holding the function key (abbreviated as "Fn") and pressing the up or down arrow keys as shown in the picture below, increases and decreases the brightness.

Other examples also shown in the above picture include pressing Fn and F1 and F2 or F7 and F8 to increase and decrease the brightness. If none of the above examples resemble your keyboard look for keys on the keyboard that have pictures of a sun or a half moon to identify the correct key to adjust the brightness.
How can I adjust the laptop contrast? Laptops only allow users to adjust the brightness of their screen. Contrast settings are not adjustable on a laptop display.
How do I save the new adjusted settings? After adjusting your laptops brightness it will retain the new settings.
Laptop brightness is still not enough or screen is black If after following the above steps your brightness is still not enough, plug your laptop into the wall to make sure it is not a power setting that is decreasing the brightness. If the laptop is plugged in but still is not bright enough, try the suggestions on the below link.

HOW TO SET BRIGHTNESS OF THE SCREEN?


Hi,

Dear User...

You can adjust the brightness and contrast of your monitor to improve the readability of text and to make digital pictures appear more like they'll look when printed.

To improve the results when adjusting the brightness and contrast settings for your display, use Display Color Calibration. (Display Color Calibration helps you adjust these color settings and others.) For more information about calibrating your display color in Windows, see Calibrate your display.

The way you adjust brightness and contrast varies and depends on your specific display.

Brightness and contrast buttons on the front of the monitor. Some monitors have brightness and contrast controls on the front and use the standard symbols shown in the following image.


On-screen menu. You can change the brightness and contrast settings for some displays by using an on-screen menu, and then setting the brightness and contrast in the resulting menu. Many times, you can view the on-screen menu by pressing a button-possibly labeled Menu-on the front of the monitor.



Thanks....

When using Display Color Calibration on a laptop, set the display to the maximum brightness setting.


Adjusting brightness automatically using adaptive brightness

Adaptive brightness is a feature in Windows that uses a light sensor to automatically adjust the display brightness to match the lighting conditions in your computer's surroundings.


To use adaptive brightness, you must have light sensors installed and enabled on your computer.


To determine if your laptop or computer monitor supports adaptive brightness, look for the Enable adaptive brightness setting in Power Options (mentioned in the following procedure) or check the information that came with your computer.


To turn adaptive brightness on or off

Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Security, and then clicking Power Options.


Under any plan, click Change plan settings.

Click Change advanced power settings.

In the list, expand Display, and then expand Enable adaptive brightness.


To turn adaptive brightness on or off when your computer is running on battery power, click On battery, and then, in the list, click On or Off.

To turn adaptive brightness on or off when your computer is plugged into an outlet, click Plugged in, and then, in the list, click On or Off.

Click Apply. Click OK.


hope this helps

HP Compaq nc6000. When power is connected the display brightness dims and becomes bright when it is disconnected. It should work exactly the other way.


You can adjust the brightness by holding down the Fn key while pushing the brightness adjusting buttons, usually marked with pictures of sun! in most laptops they are tow F keys or Arrow up and Arrow down. Dont know your modell. Set the brightness/contrast in on battery and power accordingly!

If you are unable to change the contrast with the 'fn' key and the brightness controls, usually represented in the top row of keys as a sun icons, one brightens, one dims. You may have a bad brightness/contrast inverter in your display. It's a small circuit board in the display that controls the brightness. They do fail. You can find them for most models but depending on your technical ability, they can be a little tricky to change.
