The screen on your notebook turns on, but there is no image
You press the power button, the cooling fan starts with its nice noise and then you get a black screen and nothing more. Most users at this point begin to panic and reboot. nothing wrong with that. But we recommend that you first rule out the problem with the OS. If you see that the screen is not completely black, and with a grayish tint, the problem is probably in the OS, because the screen itself works. If the color of your screen is the same as a completely turned off monitor, then the problem may be with your laptop screen. It is worth trying a hardware reset in this case.
How to perform a hardware reset
In order to successfully perform a hardware reset, you need to follow a simple algorithm:
- Disconnect your notebook from all power sources. This is both the charger and the battery (it must be removed from the device).
- Press the power button and hold it for 20 seconds or more.
- Insert the battery into the laptop and connect the power source.
- Turn on your device the usual way, if the OS prompts you to select the boot method, choose “Normal Boot”.
Why do such a procedure? It is very simple: the laptop keeps a small residual charge, which allows you to save hardware settings, even after a complete discharge of the battery. After holding the on/off button for 20 seconds we reset.
To check if the screen is working
If the screen is lit but there is no image, the problem may be with the operating system. Fixing such a problem will take much less time and will cost less as compared to replacing the screen matrix. So our goal is to rule out the most unpleasant outcome. To do this you can use the light indicators, which are on most modern devices. If the LEDs start blinking or flashing red, it might indicate a problem with the device. In this case it is worth trying to connect the laptop to the TV screen or another monitor (which is exactly serviceable). If the image appears on them, the problem with the screen of your laptop, so you have to go to the service center, to find out the causes and the severity of the breakdown.
It is worth noting that the failure of the screen without visible signs of damage or physical impact from the outside of well-known brands occurs rarely. One of the possible causes of damage is a failure of the plume. In other cases the most probable reason of damage is a shock of the case or its wetting. If you accidentally spilled tea or other liquid on your computer, then do not turn it on until it is completely dry. Otherwise, the moisture on the contacts will become a trigger and the board will simply burn out.
Why does the laptop screen go out when you turn off the charger?
This has to do with the power settings. The point of all this is to make sure that the notebook can last as long as possible on battery power. So the notebook display always gets a little dimmer when you turn off the charge, and after some time of inactivity it turns off altogether.
In a computer the video card is responsible for the image output on the monitor. Its malfunction may be the reason why the monitor screen goes out when the system unit is working. Most often the fault of the graphics card, which can lead to temporary interruptions with the signal output, is associated with overheating.
What to do if the laptop does not respond to anything?
If your notebook hangs and does not respond to anything, you can always solve the problem with a forced reboot. Most laptops do not have a “Reset” button like desktop PCs, so restart using the power button.
If the screen is gray, then, as already mentioned, it is most likely a hardware problemDiagnose
