Battery says fully charged 100%, but if I unplug it dies.
On my windows 10 laptop, it says I have 100% fully charged. It only works when I have the charger plugged in but when it is unplugged it dies. I have used very little and the issue started shortly after the warranty expired (coincidence??) I already review/updated the BIOS and drivers.

voltage
Instead, the charge level is measured by a Coulomb counter. These devices measure the current leaving/entering the battery (just like an Ammeter would), and integrate this to get an estimate of how much charge has left/entered the battery. This in turn can be used to calculate how much charge is left in the battery.
