The laptop uses ac adaptor when plugged in. Not battery. If you take a look at the battery icon when plugged in, you would see it goes to 100, then gets discharged to some level and charging back again. So the simple answer is that laptop does not use power from battery when plugged in. Battery gets charged and discharged. Does this kill battery?
This page has a good answer: "it depends" The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of the laptop.
Does keeping the charger plugged-in after a full charge somehow affect the battery in a short or long term? Thanks! You can keep it plugged in most of the time, but it is good practice to run down the battery every once in a while.
When it is fully charged, the charger doesn’t charge it anymore. If my laptop needs additional power above what the power supply provides, then the battery will provide it temporarily, but it stops when not needed. It does not charge it again until it hits a minimum level, which is set to 65% by me.
You DO destroy the battery from leaving it plugged in all the time. I've seen this first hand on all brands of laptops, even MacBook. Even if it has that circuit, the batteries hate staying at 100% charge. This causes most batteries to degrade performance significantly before 1 year and sometimes even inflate. I manage a tech repair shop.
It had reduced by 35% if kept at 40 degrees over ambient temperature. Some laptops can be kept powered when plugged into the mains with the battery removed. So that might be an option if you've got a removeable battery on yours. From my experience, it's the heat that destroys the battery.
