The time passed when we were inspired by information about the irreparable harmfulness of the computer for vision. No one denies the negative impact on our vision overly bright light or inconspicuous images that are forced to strain your eyes in order to consider the necessary parts. Today everything is easier, especially with portable computers - laptops. It is enough to know the correct sequence of actions (there are several ways), and you can adjust the brightness of the image in a matter of seconds, which is convenient for you and will not bear damage to health.
1
Do not try to detect the adjustment buttons on the monitor itself. Surely, if you have a stationary computer before purchasing a laptop, you regulated the image of exactly pressing the corresponding buttons. The laptop is completely different. To open and adjust the required parameters, you can use in several ways.
2
The first is more difficult and running through the control panel. Click the Start menu, select the "Control Panel".
3
Next, select "Screen".
4
Clay mouse at the "Brightness Setup".
5
Dragging the slider at the bottom of the screen, adjust the color saturation, depending on your preferences, discretion and recommendations of the ophthalmologist.
6
Adjust the brightness of the screen lighter or dim. If you want the monitor to work on bright color contrasts, move the runner to the right. Do not overdo it: Needless bright light gives a greater load on sight and does not most effect on health. Immediately you will not feel anything, but then not too saturated shades will seem like a faded spot and will break in the eyes. In addition to brightness, you can adjust the contrast. But also remember that overlooking the edges are complicated for perception with vision.

Another effective, the easiest way to regulate the brightness of the screen in new models of laptops is pressing the "Fn" key + up-down or right-left arrow, depending on the device model. In some laptops, the brightness control buttons are located on the top panel of the buttons and are indicated by the thematic icon, for example, the sun.

If you suddenly the screen has become dim without your direct participation, do not be afraid and do not hurry to carry to the service center. It often happens if the main power source is turned off and the device goes to work from the battery. You can independently configure the power plan, mode and other functionality both to work from the network and the battery.
If the monitor flexibility does not respond at all to any settings, perhaps the problem in the video card or something happened to the screen. In this situation, it is better not to take anything, but to seek help from specialists, especially if your laptop is on warranty service.
