4. Click on your user folder to find and view the battery report

   This is the simplest step in the process, but it needs to be repeated. In addition to completely turning off the power of the laptop, you also need to make sure that it is disconnected from the power source.

  Otherwise, you will face a serious risk of electric shock and injury to yourself.

   There may be have some rubber feet on the back panel, you need to remove them before you can replace the battery, but it depends on your laptop model.
   Use a plastic opening tool to pry off the rubber so you can remove the screws that hold the laptop body together.
   Use a Phillips screwdriver to loosen the screws on the back panel, and then gently remove the back cover of the laptop. This may require you to use plastic tools again to loosen the edges.

  Carefully connect the cable on the computer to the new battery
  Screw the battery back to the device body

7. Replace the rear panel

  Before replacing the back cover with a Phillips screwdriver, align the back cover with the rest of the laptop.
