Windows 10: HP Laptop: Battery not charging to full capacity 79%

Hi Microsoft Community


My battery HP Laptop is not charging to full capacity of 100% and I have tried all settings related to power options but in vain. Can anyone help please?


Thank you.

Why is my laptop battery charge topping at 79%?

This pertains to a 2 1/2 year old HP laptop.

I run it plugged in most of the time, but once a week I'll start the day unplugging it, and leaving it unplugged until it gets down below 10%, which usually takes about 5-6 hours.

Late last week, I got a Windows notification I'd never seen before, which I now can't quote verbatim, but it suggested using "battery optimizer" - I think that's what it was called - to "optimize" my battery. Hey, why not?

Except that

1. The next time I ran the computer unplugged, the battery drained to my needing to plug it in, in about four hours. Much faster than usual.
2. Then today I noticed that my battery was only 79% charged, though plugged in.

Below is a shot of my battery graphic:





Having been plugged in more than a day ago, it should be at, and holding at, 100%.

So how do I get the battery back to 100% charged? Is doing so advisable or not? What's a true "optimum" setting for the battery?

In asking the "optimum" question, I've never had a performance problem/issue with the computer; my main goal is that, when it is running on battery, it runs for as long as possible.

 

Acer battery won't charge

What if the battery unremoveable? Should I disassemble and remove it? also there is a switch underneath the case and around the RAM slot that prevent the laptop to turn on when the case is open and without the charger. Is that the same as removing the battery? although when turned on with charger, the laptop still see the battery. Thanks

I took the report, the design capacity was 41.440 mWh but full charge capacity is now 25.752 mWh. Is it that bad? Before this happened I believe HWMonitor also show the same number with 38% Wear Level.
Here's the report file

 

Windows 10, HP laptop battery "plugged in, not charging"

After installing Windows 10 on my HP Pavilion g6-2197sa laptop, I have had problems charging the battery. The battery icon reports something like "79% available (plugged in, not charging)."

I can, sometimes, temporarily fix this problem by following these steps:

1. Shut down
   
2. Remove battery
   
3. Boot up on AC power
   
4. Uninstall the ACPI-Compliant Control Method Battery driver
   
5. Shut down
   
6. Reinsert battery
   
7. Reboot
   

However, I bought a new battery to see whether the issue lay with my original battery, and it worked fine for a while before it also succumbed to the issue. Now the new battery no longer charges even after repeating the above process. My original battery seems to charge temporarily after I repeat the above process.

I have further noticed that my AC light flashes continuously while plugged in, whether the laptop is on or off, which it never used to do.

Also, note that the battery never charges, now matter how low the available remaining power gets - my problem doesn't appear (to me) to be a feature designed to prolong battery life.

I would really like to fix this problem permanently but am completely stumped. Cheers!
