II. Replacement Steps​​

Step 1: Remove the Back Panel

• 1. Flip the laptop over so that the bottom faces up.
• 2. Locate the screws on the back panel. Use a Phillips screwdriver to carefully remove all the screws and keep them in a safe place to avoid loss.



• 3. After removing the screws, use the pry bar we provided to gently pry open the back panel along the gap. Be careful not to apply too much force to avoid damaging the back panel clips.



• 4. Once the back panel is loose, slowly remove it. At this point, the internal electronic components of the laptop will be fully exposed.

Step 2: Remove the Battery

• 1. After removing the back panel, you can clearly see the position of the battery.
• 2. The battery is secured inside the laptop with screws. Use a screwdriver to remove the screws that fix the battery in place.



• 3. Disconnect the battery cable: The battery is connected to the laptop motherboard via a cable. Before removing the battery, you need to disconnect the cable first. Use tweezers or your fingers to carefully grasp the connector of the cable and gently pull it out. Do not pull on the cable itself to prevent it from breaking.



• 4. Remove the old battery: After disconnecting the cable, take out the old battery from the laptop.

Step 3: Install the New Battery

After entering the system, check the battery status to confirm that the new battery has been recognized by the computer and can charge and discharge normally.
