Step-by-Step Battery Replacement
Step 1: Heat the Front Screen
- Place the tablet front side down on the heating pad
- Select the Tablet Heating option and wait until it completes
- Alternatively, use a heat gun for controlled, even heating
Proper heating softens the adhesive and prevents screen cracking.
Step 2: Lift and Separate the Screen
- Use a suction cup on the screen edges to lift slightly
- Insert plastic card pry tools to carefully cut the adhesive around the frame
- Work slowly and be gentle, as flex cables are attached to the logic board
Step 3: Open the Screen
- Rotate the screen like opening a book halfway
- This gives access to the connectors while keeping the screen stable
Step 4: Disconnect Flex Cables
- Disconnect the digitizer (touch) connector first
- Then disconnect the LCD video connector by undoing its screw
- Disconnect the battery connector by removing its screw
Make sure all connectors are free before proceeding.
Step 5: Heat the Battery
- Apply heat on the rear side where the battery sits using the heating pad
- Softens the adhesive securing the battery to the frame
Step 6: Remove the Old Battery
- Carefully insert a plastic pry tool under the battery
- Gently lift and cut through the adhesive
- Remove the battery completely from the body
⚠️ Be careful: Do not puncture or bend the battery.
Step 7: Install the New Battery
- Remove the adhesive protector from the new battery
- Place the battery firmly onto the logic board
- Connect the battery connector and ensure it seats perfectly
Step 8: Reconnect LCD and Digitizer
- Connect the LCD video connector and secure with its screw
- Connect the digitizer connector and secure the screw
- Double-check the battery connector screw is also in place
Ensure all connections are secure before sealing the screen.
Step 9: Apply Adhesive
- Check the frame for sufficient adhesive
- If needed, use B7000 glue or pre-cut double-sided adhesive
- Apply evenly along the edges
Step 10: Reinstall the Screen
- Slide the screen into the frame starting from the top edge
- Align the bottom, then press sides evenly
- Use screen bonding clips or rubber bands to secure the screen
- Leave it clamped for the adhesive to cure
Final Checks
Before full use:
- Power on the tablet
- Verify battery charging
- Test touch functionality and display
- Ensure the screen is flush and edges are secure
