Battery regularly not charging.

[Sikaflex]

Hello, 

The battery of my notebook has recently become tempremental. It has began showing the "plugged in, not charging" status when it should indeed be plugged in and charging. This occurs in conjunction with a slow blink of the charge light from the regular orange (charging light) to white (charged light). However, it does not seem to happen all of the time. Sometimes it charges fine and moments later it doesn't. Additionally, the battery never seems to reach 100%, always stopping at 99% with 2-4 minutes remaining until fully charged. 

I have checked the battery and adaptor tests with the "HP Support Assistant" tool as well as the "System Diagnostics" tool. Initially, the "System Diagnostic" showed failure ID: MC64HS-84C9GV-MFGK7G-C09G03. It also suggested that the battery had a blown fuse. However, after multiple attempts, I have not been able to find that error again. All programs suggest that my battery and adaptor are OK. Yet, I continue to randomly see "plugged in, not charging" status. 

I have tried the battery and driver removal technique, updated BIOS, updated everything through "HP Support Assistant", switched between multiple wall outlets, checked the adaptor for any physically damage on the pin and cable. I even let the battery drain itself. However, my notebook continues to switch from charging to not charging. This occurs when the notebook is both on and off. Although, it seems more frequent when the PC is powered on. 

NOTE: This started occuring after about a week of disuse and around the same time that Windows (KB4023057) was installed on my PC. 

Does anyone know what my problem might be and if it is fixable? Thank you.

Have you tried checking with a different battery?

Excellent description and a great diagnosis done. It is greatly appreciated.

As the battery test has failed on your PC. It certainly sounds like a hardware issue with the laptop.

Before replacing the battery on your laptop try few steps recommended below and check if it helps.

Check if the pin inside the DC or charging port is bent or broken.

Hello, @MrRobot 

Unfortunately, I do not own another battery for which I could test. I have previously tried the steps that you described, but they did not fix the issue.

After a bit of searching around, I managed to get my PC to charge normally for a few days. Then just today it again stopped charging. Because of this, I did manage to find the error in the "System Diagnostic" tool again. 

So, did my battery blow a fuse? Is this a minor fault?

Sadly, my regular warranty is out. However, Australian law suggests that a statutory warranty may apply. 

Thanks
