About a month ago, my laptop started this behavior; once it charges to 100%, it beeps (and the keyboard backlight turns off) as though I unplugged it.  Then when it goes down to 99%, it beeps again and the backlight turns on.  I've tried rolling back Win10 updates, uninstalling/reinstalling the battery and charger drivers, and resetting the battery with the pinhole on the bottom.

As mentioned in the title, it's a Predator Helios 300.  The number on the bottom is G3-571-77QK.  Is this a known issue with a fix?
