My HP Pavilion will randomly shut down and not turn back on. If I leave it alone for an hour or so and then plug it back in, it will come on again. It mainly shuts down while using it on the charger or if I use it for long periods at a time. I tried using an HP charger because I was using an off brand one and someone told me that may be the issue, but it still will randomly shut down. When I turn it back on a message appears that says something about CMOS 502 restart. If I wait it will go away and my computer will turn on. What can I do to fix my computer so it will stop shutting down?

@Boyselm Welcome to HP Community!
I see from your post that you're getting an error on your HP Notebook. No worries, I'll be glad to assist you.
To provide you with an accurate solution, I'll need a few more details:
Have you tried to update the Bios using HP Support Assistant.
Have you tried to do a bios recovery on your PC.
Let's start off by performing a Hard reset on the notebook:
Before power resetting your computer, do the following:
Disconnect or remove all peripheral devices. Start up the laptop and test the computer by itself, and then reconnect one peripheral device at a time.
Turn over the computer and look for a battery compartment door.
If there is a battery compartment, use the steps in Reset a laptop with a removable battery.
If there is no battery compartment, use the steps in Reset a laptop with a sealed or non-removable battery.
I recommend to restore the BIOS defaults.You could restore the BIOS with this document selecting the reloading the BIOS default settings. That way it will look at the Hardware installed on the Notebook.
Once done, restart the computer and check.
The best way to resolve this issue is to revert the BIOS to the previous working version and here's how you do it:
