Battery issue

[Awesoma]

My laptop is not charging even when charger is plugged in. My warranty is expired in 2020. 
Things I have tried:

1. Updated BIOS

2. Troubleshooted power settings from control panel
3. Updated Windows

This alert message for windows 11 requirements is new. I don't know if it has anything to do with it still provided a screenshot.

Hello @Ub6424,

I first tried the calibration of battery method, I was supposed to wait for the laptop to be fully charged(LED indicator). However, the color immediately went from orange(charging) to white(full). I still waited for some time and then turned laptop on.

I get that 502 CMOS error again. After rebooting to windows, the problem was still there. So i proceeded to hardware diagnosis. 

After installing and doing the first fast system test i get the following test failure(s)   :

Hello @Awesoma 

Recommendation and solution

That a definite diagnosis ! The battery must be replaced ! Then the CMOS error 502 is permanently fixed ...

Do you need more help finding the right battery and procedure to replace the battery ?

Kind regards

[Awesoma]

It can't be helped i guess. Please do recommend the right battery model and procedures

Hello @Awesoma 

In what country do you live? It is about the possibility of ordering the battery.

Hello @Awesoma 

This is bad news: Charging Port Test: FAILED

--->>> This is also the reason why the battery is defective, because it was no longer charged and thus deeply discharged !

Either the charger or the charging port of the notebook or both are defective ( do not work 100% ).

I think your options are exhausted...

Sorry, but in your case: Service is required !
- The computer should be disassembled and checked.
- [Always recommended ] Thermal paste for CPU GPU and bridges must be renewed
- [Always recommended ] The function of the fan(s) must be checked

- Short circuit test 

- charger / charger port must be repaired / replaced !

- battery must be replaced !

- Components test

- General cleaning ...

--- HP warranty valid -> Contact HP Support

--- HP warranty expired:

If you can't do that, you should have it <serviced> by a professional notebook (chip level) repair store.

--- Alternative:

Buy a good used or new notebook !

Good luck
