1 Light On Only/Wont turn on completely

[JustRell]

I plug in the computer and then it turns on for about 5 seconds. Then the fans stop spinning and it just leaves 1 Light on.

Sorry for the bad news, but when a desktop does not even power on, you have few if any options for getting it working again on your own.

To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself. You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

But if it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do.

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:
http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

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

Good Luck

Update: I let the desktop run and came across this screen after I tried turning it on.

How old is your HP computer?

The motherboard has a small battery, usually the size & shape of a $0.25 USA coin.

If that battery is dead, your computer "loses" the current date/time.

As the message states, you need to replace that battery -- under $5.

Then, try to restart your computer.
