Nabi Big Tab HD24 Battery Replacement

Step 1 Back Assembly

• Ensure that the tablet is facing you with the screen on the table.
• Locate the four red rubber stops at the corners.
Step 2

• Use your fingers to carefully peel them off the device to reveal the screws underneath.
Step 3
• Use a Phillips #1 screwdriver to remove the 9.5 mm screw in each of the four corners.
Step 4
• Flip the tablet over such that the screen is facing upwards.
• Locate the the 4 small openings on the sides of the tablet.
• There should be 2 on the bottom of the tablet, 1 on each side of the tablet viewing it from the front as if you were using it.
• Do not confuse the openings with the charging port or the USB ports. The openings will be labelled with an icon of a small fan, the Nabi logo.
Step 5
• Insert a metal spudger into one of the openings and carefully pop the device open by applying a steady downward force.
• Repeat for the other three openings.
Step 6
• Flip the device over so that the back assembly is facing you.
• Use a plastic opening tool to carefully pry open the device from its hinges.
• Take care when opening the device as there are cables running internally that are connected to both the front and the back assemblies.
Step 7
• Locate the white port that connects the back panel to the circuit board on the back of the display.
• Carefully pull the plastic connector straight out.
Step 8
• Be careful of the aluminum foil tape, as it can easily rip.
• Carefully lift up the aluminum foil tape with your fingers so that the ribbon connector reveals itself.
• Do not try to pull the ribbon cables off the screen as there is a plastic piece surrounding the ribbon cables glued onto the metal display.
Step 9
• Firmly press the two switches located on the sides of the connector and disconnect the connector from its connections.
• Leave the connector disconnected but still intact with the metal display.
Step 10
• Use a plastic opening tool and carefully push it underneath the grey plastic case surrounding the ribbon cable.
• Apply a downward force to carefully peel the grey plastic off of the metal display.
Step 11
• Locate the two cables running on both sides of the device found at the bottom side of the screen.
Step 12
• Carefully grab both sides of the white plastic piece with your fingers and gently pull directly upward.
• Do not pull from the red and black cable as it is not very sturdy and may come undone from the connector.
Step 13 Battery
• Locate the battery, the large black rectangular component, on the side with all of the circuit boards.
• The battery is a McNair Li-ion Polymer Battery Model #: mlp2462113-4s.
Step 14
• Locate the bundle of wires connecting the battery to the power regulator, which is right next to the battery.
• One bundle of wire contains two black, one yellow/white, and three red wires in this bundle, while the other bundle is a twisted black and white wire taped alongside the previous one.
Step 15
• Remove the black tape holding down the two bundles of wire.
• The black and white wire bundle does not connect to the battery, so moving it out of the way will make taking the battery out easier.
Step 16
• Locate where the red/black/yellow wire bundle connects to the power adapter.
Step 17
• Disconnect the wires from the power regulator by pulling the white connector straight out.
Step 18
• Unscrew the six black 4.5 mm Phillips #1 screws holding the battery in place.
• Lift out the battery and replace with your new one.
