Often, new owners of mobile PCs have such a question, how to make the screen on a laptop brighter. There are no standard buttons, as on a regular monitor, and this fact is misleading for most users. But not everything is as complicated as it seems at first glance. In most cases, it is enough to use a keyboard shortcut to solve this problem. If this does not help, then we look at the energy consumption plan. If nothing happened, you need to check the correct installation of the drivers and repeat everything again. And only then it makes sense to contact the service center for help. Most likely, the malfunction is at the hardware level.
Using the keyboard
The easiest way to solve the problem is how to brighten the screen on a laptop using the keyboard. To do this, we need a function key labeled "Fn" and those on which the "sun" is depicted. The first of them is located in the bottom row between "Ctrl" and "Win" (it shows the logo of the "Windows" operating system). In turn, with the "sun" there should be two keys. They differ in the direction of the arrow. In one caseit is turned up (toward the screen), in the other down (to the touchpad). We are interested in the first of them. After finding all the keys of interest to us, hold down "Fn" and, without releasing it, press the second one. At the same time, the brightness of the screen should begin to increase. This is the simplest answer
on how to make your laptop screen brighter. But this key combination does not always work. If the desired result is not obtained, then proceed to the next step.
The second way to make your laptop screen brighter is to change your power plan. To do this, open the "Start", then go to the "Control Panel". After opening it, you need to find an icon that says "Power Options". Double click on it with the left mouse button. A window with installed power plans will open. Here you need to choose a plan that provides high performance (that's what it's called). Opposite it, you need to check the corresponding box, while the screen should become brighter. If this does not happen, then return to the "Control Panel" and go to the "Device Manager". In the window that opens, check for the presence of all the necessary drivers. If they are not installed on some device, then a question or exclamation mark is placed in front of it. In this case, we launch the disk that came with the laptop in the kit and install them. As a last resort, if the disk is lost or it was not there, we download them from the official website of the manufacturer. After that, we repeat everything again. If there are no problems with the drivers, then it is better to attributelaptop to a service center.
If nothing worked
All of the above has been done, and not a bright laptop screen left? In this case, it's all about the hardware resources of the PC. This may be a problem with the cable (the contact has come off or it has frayed), the backlight has burned out, or something else. In any case, it must be disassembled and the cause of the malfunction determined. It is difficult to do this on your own, especially for a novice user. Therefore, you will have to contact the service center, where this issue must be resolved.
As part of this material, it was described how to make the screen brighter on a laptop in various ways. The easiest way to do this is with the keyboard. It is enough to hold down two keys - and the desired result in most cases will be achieved. It's a little more difficult to change the power plan. If none of the above methods worked, then you need to check for the presence of all the necessary drivers. If necessary, install them and repeat everything again. And only after all the manipulations carried out, it makes sense to contact the service center for help. Most likely, problems at the hardware level, and they can only be solved using special equipment.
