Introduction

This guide demonstrates how to remove and replace the battery of the device in the case of a dead or malfunctioning battery.

Unscrew the two 2.70 mm Phillips #00 screws on the side of the tablet that has the buttons and the headphone jack (bottom side when holding upright).

My unit does not have screws. How do I open it? Do I pry it opened between the front and back panels?

CAUTION: When removing the back panel of the tablet, take caution around the speaker. This is located in the lower right corner when looking at the back of the tablet. There are two wires inside connecting the tablet back panel to the device itself and this connection may be severed if the back is pulled off without care. This connection is shown circled in the pictures.

Slide a plastic opening tool in between the edge of the back panel and the the top edge of the device. Run the plastic opening tool along the sides of the tablet while keeping it in the crack between the tablet and the back panel to create an opening.

Apply pressure using your hand to pop the back panel off slowly, taking extra care around the speaker connection.

The back panel should now be disconnected from the device. This provides access to the components of the device for repairing and replacing parts of the tablet.

Using tweezers or your fingers, begin removing the yellow tape holding the battery down to the device. Using tweezers or your fingers, begin removing the yellow tape holding the battery down to the device.

The battery is very fragile, so this process may cause some damage to the old battery during removal. Take extra care if you need the old battery to remain intact. The battery is held to the back of the device by an adhesive under the battery. Use a spudger to slowly separate the battery from the glue underneath. Do not use a metal ruler as shown in the photo. Take care not to bend or puncture the battery, which can cause a fire.

Now you will need to disconnect the red and black leads from the battery to the circuit board.
  • Now you will need to disconnect the red and black leads from the battery to the circuit board.

  • This can be done by either cutting the wire ends with a cutting tool, or by de-soldering the tips using a hot soldering iron tip.

Apply heat to the solder holding each of the black and red wires to the circuit board while gently pulling with tweezers. When hot enough, the wire should pull away freely from the joint.

Find the red and black wires coming from the battery. You will now need to solder the tips back onto the circuit board where you removed the old connections.

Place the red wire tip on the positive terminal. Hold the solder strand so that it is touching the terminal and tip, and apply heat with the soldering iron until the two fuse together and produce a small amount of smoke.

Finally, use a heat-resistant tape to secure the battery in place to the device. Center the battery in the middle and apply strips of tape until it sits securely mounted to the device. Your battery is now connected and secured to your tablet Your battery is now connected and secured to your tablet
