Laptop shuts down at 96% battery and "Plugged in, not charging" issue

Hi all,

Laptop is a 5 years old HP Pavilion DM4-2153ca.

Issue started a few months ago when laptop was shutting down at 63% battery, and when I plugged it it would charge until 9x% and then say "plugged in, not charging".
In the meantime I upgraded to Windows 10 and the issue wasn't solved.
I formatted and did a clean install of Windows 10 and still not solved.
HP advised I revert back to Windows 7 as this is the "original" OS for my somewhat old laptop.

So I just re-installed OEM Windows 7 Home Premium SP1 that came with the laptop, and the issue got worse, now it shuts down at 96%.

I also uninstalled and re-installed battery drivers, didn't work.
I tested the battery in the HP UEFI Support environment and it passed, so I can't calibrate it.

At this point I don't know what to do, and I don't think it's a battery related issue because it never fully discharges. The laptop just shuts down before! Help!!

This is battery issue, nothing relates to windows &or battery drivers, if any.

If you leave the battery plugged in all the time, with the main power on.
Sooner or later, battery will not be able to charge properly, as you encountered now.

The percentage you see may not be real, hence it may force the laptop to shutdown without warning.
There is nothing you can do, unless either get a new battery, or use it as home with main power on.

agree with Eric... My wife had the same problem. Bought a new battery and it's been solved.
