hello everyone I want to show you how to take the laptop battery apart all we need is a cutter and cheap Chinese screwdriver something cool and fancy doesn't work as good as this one first test find the weak spot somewhere along the seams and pry until that tag pops open continue to pry the case cover by moving around the edge until the entire top is free here we go now we can see six battery cells in charge controller this is 18 650 cell with 3.7 volts these batteries are paired and pairs arranged in series if your laptop still charging the battery but it works just as five minutes it's not too late to change the cell but it doesn't charge apparently the charge controller in protection mode which means you need specialized equipment and original firmware for flashing for just a few steps to edit trash can you
