Windows 10: 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.

Battery says 79% available and not charging

Hi all...

My Toshiba Laptop says it has a remaining battery charge of 79%. It then says it's not charging. It's supposed to charge up to 100%. There is an application that has to do with the battery life from Toshiba that says "No Peak Shift Patch". It says to install it before the "TOSHIBA eco Utility". When I installed the "No Peak Shift Patch" application, that is when I started seeing my battery not charging all the way up to 100% although it still charges.

If someone knows of any solution, that would be appreciated!

Thanks!
