Perform Simple Checks
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.
4. 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.
If the external displayer doesn’t show anything, the motherboard or graphics card may be broken. Also, you need to ask an after-sales service for help.
5. Sometimes, the laptop temperature is too high; in this case, if you often play games despite the heat dissipation performance bot being good, as a result, the screen goes black randomly due to the graphics card temperature being too high.
Check your graphics card to see if it’s burned out. If not, please clear the dust thoroughly, reclean the exhaust system, apply silicone, and replace the fan.
