Laptop won’t charge when powered on

[Al_13]

So I own an HP laptop and first of all, I can’t find the Product name on the back of it anywhere. I do have these:

The product number is X7T78UA#ABA

the model number is 15-ba009dx

The main issue I have is that I’ve had this device only for about 1–2 years, and about a week ago when I plugged it in it didn’t charge. I thought it may have been the charger, and I tried different ones, but after trying three different chargers that worked fine on other HP computers I realized that wasn’t the case. 

The computer charges just fine when powered off, and it has a red light when it isn’t fully charged on the side of the charging port. But when I plug it in when it’s on, the light stays a steady solid white and sometimes it flashes and sometimes it doesn’t. This is getting really annoying because when I try to get work done I’m forced to stop and wait until the computer charges again. 

I didn’t mess with any setting or install anything new recently. I just woke up and it wasn’t working correctly. There are also no error messages at all!
