Question Why does my laptop screen turn off when I plug it in?

[David534215]

After a few months of my laptop running smoothly, the screen of my laptop suddenly turns black when I plug it in but when I unplug it it turns back to normal except for a small glitch on top.

Another thing to note is that when I attach a second separate monitor, the screen of the second monitor works fine works even if its plugged in

sounds like the charging port is damaged and causing a short. What laptop is it?

You can try reseating the display connector, but if that doesn't fix the issue you will need a new motherboard which can cost several hundred dollars.

You can also try an RMA if the laptop is still underwarranty.

Oh ok, thanks for your help. I wanna ask though, what causes this problem?

what causes this problem?

Could be age, could be just wear and tear, could just be accidental mishandling of the laptop or charger. Many possible causes, and we won't know for sure unless we have someone like Louis Rossman look at it. He is a very smart repairman who has gone toe to toe with Apple in a courtroom, but he runs his own business and he's very busy.

While I may know quite a lot about laptops and PCs, unfortunately I don't know everything. I just know about the effects and symptoms of many issues from owning hundreds of laptops myself.

I'm very skilled with Dell and HP laptops, less so with MSI, ASUS, etc. General knowledge can often be applied across brands.
