Laptop will not turn on or charge

[Mkl6]

My laptop was fine, I was using it for like 4 hrs today before it suddenly shut off. I was charging it so I know it's not dead. I plug the charger in but there's no light. I know the problem isn't in the extension cord I'm using bcz it's lighting up and I've tried it with other devices. My battery is built in so I couldn't take it out. I don't remember laptop model but it was a pavilion. Its a few years old I'd say almost 3 or so. Idk if that helps in determining the model but it's gold in color and power button is a tiny rectangle on the top left that lights up

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it. And the problem with that is, while HP does do repair work of some sorts on PCs still under warranty, they generally do NOT do repair work on PCs out of warranty because they are not a general purpose repair facility. You would have to contact them in advance to see (1) if they are willing to work on it, and (2) if they will provide you any kind of repair cost estimate.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
https://www.service-center-locator.com/hp-hewlett-packard/hp-hewlett-packard-service-center.htm

If that link does not get you a useful page, then use the main HP link:

If you can't get assistance from HP, then you will have to seek out a local laptop service facility to have them examine it for you.

Good Luck
