    • Place your Chromebook upside down.

    • Utilizing the precision magnetized Phillips #0 screwdriver, remove all thirteen 6.5 mm Phillips screws that secure the back cover.

    • Before doing anything, make sure your Acer Chromebook is completely turned off.

    • Disconnect the connector that attaches the battery to the Chromebook with a pair of pliers or tweezers.

    • Alternatively, you could use your hands, as it may be difficult to unhook the connector.

    BEFORE disconnecting, first get the battery loose in the laptop case. At the front of the battery (bottom of this picture) there are two tiny rectangular tabs that stick off the battery and engage in two matching sockets molded into the laptop case. Push the battery toward the hinge (upward in picture) so that the tabs come out of the sockets and you can swing the battery up to free it. NOW disconnect the 8-pin battery connector. Much easier.

    • Disconnect these cables from the motherboard using the tweezers.

    • Alternatively, you may use your hands.

    • Pull out the fan.

    These two wire connectors are exactly like snaps on clothing, except super tiny. They want to pop straight UP, i.e. perpendicular to the board.

Huh? This doesn’t tell how to replace the keyboard.

Dave Burton - Contestar

After the last step unscrew the 3 screws at the top of the device holding the display assembly to the top portion, then bend those up and you can pull the whole cover with the keyboard and touchpad off and slide the new one in.
