The laptop screen began to fade during work, what to do?
Question from the user
Please advise how to solve the problem with a Lenovo laptop. When loading Windows (after the logo). the screen goes out recently (you can hear the operating system is loading).
What to do to turn on the screen, or only in the service? It all started after the laptop connected to a big screen TV. It must be something burned out?
Thank you in advance.
I should note that this problem is quite common. Happen as a consequence of software reasons (malfunction in software operation, wrong settings, etc.), and other reasons.). And also due to hardware problems. From experience I can say that in most cases the problem is in the software.
Judging by your question and its description, you have wrong screen settings. t.е. the notebook “thinks” it is still connected to the additional screen and transmits the picture to it. Let’s try to fix it now.
By the way, if you see any artifacts on your screen (stripes, ripples, etc) you may want to take a look at the picture.), I also recommend to familiarize with this article
How to perform a hardware reset
To perform a hardware reset.
- Unplug your notebook from the mains or other power source. This includes disconnecting the laptop from the charger, as well as removing the battery.
- Press and hold the power button for about 20 seconds
Why do we need it? It’s very simple. The notebook stores the residual charge of the capacitors to save the settings. If you turn on your notebook without power this charge is gone and the settings are lost.
If these actions did not give any result, go to the next point.

Why you should contact a service engineer
If none of this helps, there may be several reasons. First, the cable itself is defective. This is easy to check: Simply plug in another. It could be that the connector on your laptop or monitor is out of order. Then fixing it at home is fraught with consequences. Practical solution requires technicians who can identify this and fix it.
It is easier when you do not have the correct video jack on your TV (HDMI 1 or HDMI 2). Or it’s the drivers. Here you should go to the official Lenovo website, download the latest versions of programs. In the second case TV tuning via remote control will help.
Troubleshoot, if it is related to the “iron”, in the home is quite problematic. the real sources of problems can not be detected. Can’t find why the external monitor can’t be detected? Contact a qualified professionals who will diagnose your notebook and conduct a quality repair.
Overheating, dust cleaning
If the ventilation holes and in general the cooling system of your laptop is clogged with dust. then the laptop when overheating can simply shut down.
By the way, in some laptops (eg, in some models from Asus) when overheated the screen appear different flickers, and even the screen goes out.
In general, it is desirable to clean any laptop from dust 1-2 times a year (depends on the conditions in which the device works).
Some laptops are fairly easy to disassemble, and to clean it, you just take off the back cover and gently blow everything away; other models. to get to the radiator you have to “gut” the whole device (which I do not advise people without experience to do).
