Battery Plugged in but not charging - White light on even after shutdown.

[Labmer_RF_120]

Hi,
I recently replaced my battery. It worked fine. 2 Weeks Later, I put my laptop to sleep and the next day, the battery is not charging when plugged in. The white light (near the charging port) is always on even after shutdown - and sometimes blinks.

I followed the steps earlier stated in the forum for the same issue (Solved: Hp laptop battery plugged in but not charging - HP Support Community - 6118595).

I uninstalled Microsoft ACPI Method Battery and restarted, but issue is not fixed. I have uninstalled MS ACPI Method Battery and shutdown and waited more than 12 hours and restarted with the charger plugged in - Issue still not fixed. I have waited 1 hour and restarted multiple times - Issue still not fixed.

I ran battery tests few times - It said "Primary Battery - OK".
My battery is at 8% now, and it's not charging. The Battery Test now says "Unknown".
Please help.

Thanks Echo_Lake for the timely response. I noted your recommendations, but unfortunately, I couldn't afford the down time that may come with visiting the support centers. 

However, HP recently sent a BIOS Update & I installed the update. The laptop was charging normally for 2 days and then the issue reoccurred. 

Then, I followed this post - Plugged in, not charging after BIOS update - HP Support Community - 6599580  . According to advice here, I followed the following steps - 

1. Uninstall MS ACPI control Method battery.

2. Force shutdown laptop - holding power button down for 5 seconds.

3. Unplug charger, Press & Hold power button for > 15 seconds.

4. Plug charger back in. Did not turn on laptop. Left for charging. 

And then battery is charging to 100%. Switched on laptop after some time(>6-10 hrs). Battery charged to 100%.

Then I Used laptop without charger plugged in. If I plug in charger when battery is >~60%, it charging to 100% again. However, If I plug in charger when battery is at 35% or lower, then Battery not charging - White light appears after few seconds. But if I follow the above 4 steps again, then battery is getting charged to 100% overnight ( I am following the steps daily at the end of the day). 

Please let me know if there's a software hack to fix the issue or if visiting Support is my only option ?

Thanks.
