I dunno, try another charger or maybe the laptop's charging port is shot.

If a laptop isn't charging, it could be one of a few things.

Firstly, as StarWars said, It could be a case of the rectangular box on the charge cable that might be shot; in which case check it to make sure there's no blue/green liquid coming out of it. Find another cable with the same socket connection and same amp/voltage output and try that.

Secondly, it could be the port on the laptop itself as StarWars said, so if your laptop battery is physically removable, I'd recommend removing the battery, then trying to power the laptop via the cable without the battery in the laptop. If the laptop has power to it, then the port is fine. If there's no power to it then you need to get the port fixed.

Thirdly, it could be that your laptop battery is on its way out. This could be due to at least two reasons; 1. The battery simply isn't a good one and needs a replacement. 2. When your battery is 100% charged you keep the power cable plugged into the laptop, causing the battery to take in more power than it needs, forcing it to over discharge energy and slowly kills the battery (and the battery not charging is the first sign of its end of life if this is the case). Ultimately that will mean you should also get the main battery replaced, and in future once the battery is 100% charged, remove the power cable until the battery gets low, then plug it back in. Never keep the cable in permanently.

I hope this information might help assist you. Other than that, you could try turning it off and back on again!

On most laptops you have a bettery indicator icon. If on Windows, it is usually in the bottom right corner. If you hover your mouse over that icon it will tell you what percentage it is at. Eventually it will get to 0% but will remain "plugged in". This means that your laptop now relies completely on being plugged in with the charger cable all the time as the battery is officially dead.

The battery icon is a very good indicator for those who have laptops where the battery is not physically removable without taking the laptop apart.

Your laptop should remain powered on while the charger cable is plugged in even if the battery is dead.

The best bet would be to get an official diagnosis by taking it to a repairman, since they can look at it thoroughly whereas I cannot.

FIXED! Well, for the most part. But I figured it out. My house has a sorta kinda power problem. Like some electronics won't work on some parts of the house. But it's so God damn random because sometimes they do work. I suspected this, but another problem is my charger is weak. Needs to be in a very specific angle in order for it to charge. Which is why it took me this long to figure it out.

Right now, the charger is the problem. A fucking charger should be able to charge at any fucking angle no matter what. -_-
