Often, new-made owners of mobile PCs have the question of how to brighten the screen on a laptop. There are no standard buttons, like on a regular monitor, and this fact is misleading to most users. But not everything is as complicated as it seems at first glance. In most cases, it is enough to use a key combination to solve this problem. If this does not help, then look at the energy plan. If nothing works, you need to check the correct installation of the drivers and try again. And only then it makes sense to contact the service center for help. Most likely, he has a malfunction at the hardware level.
Using keyboard
The easiest way to solve the problem is how to brighten the screen on a laptop using a keyboard. To do this, we need a function key with the inscription "Fn" and those that depict the "sun". 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" should be two keys. They differ in the direction of the arrow. In one case, it is turned up (to the screen), in the other down (to the touchpad). We are interested in the first of them. After finding all the keys that interest us, hold down “Fn” and, without releasing it, press the second. At the same time, the brightness of the screen should begin to increase. This is the simplest answer.
on how to make a laptop screen brighter. But this key combination does not always work. If the desired result is not obtained, then proceed to the next step.
Energy plan
The second way to brighten the screen on a laptop is to change the energy plan. To do this, open the "Start", then go to the "Control Panel". After opening it, you need to find the icon with the inscription "Power". We double-click on it with the left mouse button. A window opens with the installed power plans. Here you need to choose a plan that provides high performance (it is called that). Opposite it, you need to set the corresponding flag, while the screen should become brighter. If this does not happen, then go back to the “Control Panel” and go to the “Device Manager”. In the window that opens, check for all the necessary drivers. If they are not installed on any device, then a question or exclamation mark is installed in front of it . In this case, run the disk that came with the laptop in the kit, and install them. In extreme cases, if the disk is lost or it was not, 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 take the laptop to a service center.
If all else fails
Everything described previously done, but not a bright laptop screen remained? In this case, it is all about the PC hardware resources. This may be a problem with the loop (the contact has gone or it has frayed), the backlight bulb has blown, or something else. In any case, it must be disassembled and find out the cause of the malfunction. 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.
