In this post I’ll try to list a few possible causes of fix the half screen black and solutions for this problem, go through each step until you find the real cause of the problem, I have to warn you that if your laptop is still under warranty it’s not recommended to open it up or miss with any internal components.
According to users’ feedback, computer getting a black screen is a common issue. Some users have reported that the black screen doesn’t always occur. However, when it does, the laptop screen goes black for a second; then 5 seconds later, it happens again. It can even repeat several times.
An unexpected black screen can happen on Asus, Lenovo, HP or Dell laptops in a number of scenarios in Windows 10, which may stem from hardware issues and logical faults – for example, a connection problem with your display, power supply, hard disk, internal memory, graphics card, virus attack, mistaken operations, software incompatibility and more.
The Video Chipset is Broken
First you need to check if the video chipset is broken or not, you can do that easily by connecting your laptop to an external monitor, if it works then you’re somehow lucky because the chipset or the motherboard is fine (you’ll have to replace the screen though) but if it doesn’t the problem persists then there are two reasons for this, whether it’s the connecting cable (the one that connects the motherboard to the screen) or a broken video chipset or motherboard.
The Connection To The Screen is Broken
The connecting cable or the ribbon cables are another reason why your laptop acts this way, it’s an easy fix if you’re an experienced person who can deal with the internal parts of a laptop,
The Display is Broken
If you like I mentioned at the beginning stepped on the screen by accident or let’s say one of your little kids or nephews did then you can tell right away that your screen is broken and you need to replace it, don’t go for cheap ones though and it’s preferable if you let a professional do the swap and not you if you’re not skilled enough.
Bad or Outdated Video Driver
Well… Let’s hope it’s a bad or outdated video driver because this one is easy and won’t cost you anything, you can simply update your laptop drivers by installing a software called Driver Booster.
Simply Check Screen
The most common and critical hardwares that can cause laptop black screen are the power supply, liquid crystal display, memory bank, hard disk, motherboard, etc. So it is necessary for you to troubleshoot these one by one.
1. First, check your power supply. Sometimes, for a laptop, if the power itself has a problem, it is possible that the screen goes black even though plugging in an external power supply.
In this case, you can choose to remove the power from your laptop and plug in an external power supply. If the Windows can boot up, perhaps the internal power is corrupted. Just go to buy another to replace it.
2. If the power indicator is on all the time and the external power is plugged in properly, then a random laptop black screen is not caused by the power. So you need to carefully check the cooling fan port to see whether there is wind and check if the hard disk indicator light is on.
3. If there is no problem, restart your laptop and hear if there is a continuous beeping voice. If yes, perhaps the memory stick is loose. Just plug it back in.
. Next, check your graphics card or liquid crystal display. Connect the external monitor to the external display interface of the laptop, restart Windows OS and see whether the external display can work normally.
If yes, the motherboard, CPU, hard disk, graphics card, and memory don’t go wrong. And perhaps it is the liquid crystal display that leads to the issue laptop screen keeps going black. And then you need an after-sales service to fix the displayer.
