Step-by-Step Battery Replacement Guide
Step 1: Power Off and Screen Removal
For this repair, we are using a heating pad.
Place the tablet screen-side down on the heating pad and select the tablet or mobile heating option. Allow the heating cycle to complete fully so the adhesive around the screen edges softens evenly.
If you are using a heat gun or hairdryer, apply gentle heat around all four edges of the screen. Keep the heat source moving constantly and avoid overheating one area for too long.
Once the adhesive is sufficiently softened, attach a suction cup near the bottom edge of the screen and gently lift to create a small gap between the LCD and the frame.
Insert a plastic pry tool or card into the gap and carefully slide it along the edges to cut through the adhesive.
Avoid inserting the tool too deep, as display flex cables are located underneath the screen.
Work slowly around the entire perimeter until the screen is fully released.
Next, gently lift the LCD screen and flip it carefully, allowing it to rest on the tablet body without straining the flex cables.
Do not pull the screen away forcefully. Ensure the screen is supported at all times to prevent cable damage.
Step 2: Disconnect Battery and Display
Remove the metal bracket by undoing the securing screw.
Disconnect the battery connector.
Next, undo the two screws holding the LCD connector bracket.
Disconnect the LCD connector plug, and carefully remove the screen unit from the body.
Step 3: Battery Removal
Take out the faulty battery from the tablet.
If the battery adhesive is strong, apply gentle heat to soften the glue underneath.
Carefully slide a pry tool under the battery to loosen it.
Once the adhesive is released, remove the battery completely.
Step 4: Installing the New Battery
Place the new battery into position using fresh adhesive.
Reconnect the LCD connector plug, followed by the battery connector.
Before sealing the device, test the screen and touch functionality to ensure everything works correctly.
Step 5: Reassembly and Screen Installation
Secure the LCD connector bracket using two screws
and the battery bracket using one screw.
Before installing the LCD screen, ensure there is enough adhesive.
If needed, apply B7000 glue or use new double-sided LCD adhesive.
Gently slide the screen into place from the bottom first, then align the top.
Apply light pressure around the screen edges.
Use bonding clips to secure the screen and leave it for some time.
If bonding clips are unavailable, use rubber bands to hold the screen firmly in place.
