Black Screen when Laptop charger is plugged in.

One night, I downloaded the Windows 10 update. Note that I downloaded the update with my laptop unplugged. The next day, I try to use my laptop only to find that when I plugged in the charger, the screen went black, black as in as if it had turned off. I
unplugged my charger, and it worked fine. So every time I plug in my charger the screen blacks. I already tried to change my power plan, and it worked yesterday, but all of the sudden it didn't work today.

I have an ACER Aspire E 15

EDIT: I just ran an SFC Scan, will edit again if problem fixes.

Laptop goes to sleep mode after plugging in charger

Hello.

I have a ASUS X550C laptop. The original charger broke, so i bought a charger for it at my local market (the brand is "Innergie"), which also works for ASUS laptops. Now since i got this charger, i was experiencing issues where my laptop would randomly go to sleep mode, however, i resolved this issue by turning computer on, removing the charger, and plugging it back in. That seemed to fix it. However, recently, this method stopped working. My computer runs completely fine when it is unplugged, however, when i plug it in, i get a "Low battery" warning (even though i HAD 72% battery), and the laptop immediately goes to sleep mode. Trying to turn it on is useless. It will only turn on if the charger isn't plugged.

Any advice?

PS: I have already changed all my power & sleep options. Everything is set to "Never".
