We sometimes encounter problems when it comes to the screen of our laptop. Often, the laptop turns on, we see the backlight of the keyboard lighting up, and we hear the fan running. However, the screen might not turn on properly or light up.
While this may pose a problem for most users, you will be pleased to know that there are still remedies for this situation. There are several factors to rule out when a screen fails to turn on properly. While you can consider that the screen might be damaged, there are more reasons as to why this happens.
In this article, we will teach you how to fix a laptop screen that won’t turn on.
How to Fix a Laptop Screen that Won’t Turn On
The ease of fixing issues like this will vary. It will depend on the reason behind it and the severity of the damage. Some fixing can take a couple of minutes while some methods will bring you hours.
One of the things that you should do first is to check the configuration of the bootup process of the laptop. A misconfiguration of the bootup system may cause the laptop screen not to function correctly. With this, you can rule out the possibility of hardware damage or malfunction.
1. Boot Up Problem
When checking the status of your laptop screen, you also need to make sure that the laptop has finished its power cycling. In simple terms, you should check whether the computer has fully finished booting up. Some people mistake a screen not turning on to be a hardware issue when in fact, the laptop is just having problems recovering from the Sleep mode of the operating system.
To check this, you need to power off the laptop by holding down the power button for a couple of seconds. When the laptop is fully turned off, restart the laptop and see if the screen problem is still apparent.
2. Clear the CMOS
Another method you can do is to clear the CMOS. You can do this by wiping the BIOS memory on the motherboard. With this, the BIOS settings will revert to default settings. This is because a misconfiguration of the BIOS settings can be a reason behind the screen not turning on. Make sure to save the changes you have done with the BIOS Settings.
3. Check the Power Supply Voltage
Another reason for a malfunctioning laptop screen is an error in the power supply voltage. This often happens when the input voltage directed to the power supply is incorrect.
When this happens, not only the screen will be damaged but even the entire laptop unit. With this, you may expect the laptop to malfunction.
If there is any damage to the power supply, then you have to replace it as soon as possible. After installing the new power supply for the laptop, you need to have the PC plugged in for a couple of minutes before booting it up. This will give the CMOS battery enough time to charge up.
4. Reseat the PC
Another way to fix a screen that won’t turn on is by reseating the components of the laptop. This method entails reestablishing the various connections of the computer and is often an effective fix for most laptop problems.
To do this, you need to check if the components inside are well installed and connected. These include video cards, hard drives, and other vital hardware. However, before doing this, you need to be well versed in opening the back panel of the laptop. Don’t attempt doing this if it is your first time doing it and you do not have the necessary background the knowledge about how these components are placed.
5. Re-enable the Screen
One of the most common yet overlooked causes of a laptop screen not turning on is the possibility of it being disabled. This is a common mistake done by people around the world.
To re-enable the screen, you need to press the Fn and the hotkeys which are usually F1, F2 or F4, depending on the laptop brand.
If the steps mentioned above do not work, you might need to look into the manual of the laptop to know how to disable or enable the laptop screen.
6. Connect to an external monitor
If the steps mentioned above still does not work, you may try to connect it to an external monitor. If the external monitor can show the supposed display of the laptop, then you can proceed with the next steps.
The first thing you need to do is to update the drivers of the laptop. The reason behind the malfunctioning screen might be brought about by outdated or incompatible device drivers. If this is the case, then you should check the internet for updated drivers for the laptop screen.
There are also some programs that aid in the updating of device drivers. Such a plan includes Driver Easy. The program can analyze the laptop and check for any outdated drivers. The program also looks into the internet for updated and compatible drivers for the old ones. With this, you need not worry about downloading the wrong drivers.
To use the program, you need to launch the Run Driver Easy app. Click on the “Scan Now” button to start the analysis of the existing drivers. The program will then proceed to the study and then detects any outdated or malfunctioning drivers.
To apply the changes, you need to click on the Update button right next to the hardware component or device it is connected to. You can also opt for the “Update All” option which automatically updates all the drivers as based on the scan.
7. Have your laptop serviced
If the steps mentioned above still don’t work, and if the problem far exceeds the scope of knowledge you have with the matter, then the next best thing to do is to have the laptop serviced. Bring your laptop to the manufacturer support office and have them check the malfunctioning screen.
