Introduction

Use this step-by-step guide to replace the Light Sensor Module on your Acer Iconia Tab A100.

  1. Start at any side of the tablet.
    • Start at any side of the tablet.

    • Begin to take apart the tablet ,with a plastic opening tool, along the sides of the tablet.

    • Work your way around the tablet.

    • There are four side pieces in total.

  2. Placed on each end of the tablet are 4mm Philips screws.
    • Placed on each end of the tablet are 4mm Philips screws.

    • Unscrew the 4mm Phillips screws with a Phillips #00 Screwdriver.

    • There are five 4.0mm screws in total (including the 4mm Phillips screw at the bottom of the tablet).

    • Carefully separate the back piece from the device using a plastic opening tool.

    • Remember to open along the entire perimeter of the tablet.

    • Turn the tablet over to locate the battery.

    • Locate the large blue and black object at the bottom of the tablet with the plus and minus sign.

    • Unscrew the 4mm screws located around the battery.

    • There are five in total.

    • Locate the battery cables and the tip of a plastic spudger or opening tool to gently push the connector head out of its socket.

    • Use your fingers or the flat edge of a plastic opening tool to lift the battery up and off of the device.

    • Be sure to not have any water around the device while removing the battery.

    • Be sure to be cautious while removing the battery and remove carefully; avoid ripping the wires attached to the battery.

    • Locate the I/O Board FPC (a long orange strip) .

    • Gently peel off any tape securing the FPC to the main plate.

    • Locate the two connectors at each end of the FPC.

    • Use the flat edge of a spudger tool or your fingernail to gently pry each connector straight upwards out of its socket, then remove the FPC cable from the unit.

      • While a metal spudger tool is shown here, it is best to use a plastic spudger / opening tool when possible, and only use a metal spudger as a last resort!

    • You should now see the yellow-colored strip on the metal base marking the location of the FPC

    • Locate the L-shaped I/O Board.

    • Locate the gray 3G Antenna wire.

    • If the gray 3G Antenna wire is connected to your I/O Board, disconnect it. If for some reason the 3G Antenna wire is already disconnected from the I/O Board (as it was in this device) simply lift it out of the way.

    • Locate the microphone cable.

    • You should be able to gently pull it out of its socket using only your fingers.

    • The spudger is used in the photo merely to hold up / identify the disconnected mic cable head.

    • Locate the light sensor connector.

      • Use the tip of a spudger or your fingernail to lift up and flip the small retaining flap on the connector. The light sensor ribbon cable should now be free, so simply pull it out.

      • This is a ZIF (zero insertion force) connector, which requires no force to remove / plug in the connector.

      • Please make sure you lift up on the small retaining flap on the connector, not the connector itself!

    • Use a Phillips #00 screwdriver to unscrew the single 3.0mm Phillips screw next to the light sensor connector.

    • Carefully lift the I/O Board off the device.

    • To remove the light sensor, use the flat edge of a spudger, plastic opening tool, or your fingernail to gently pry the top of the square connector straight up and out of its socket.

    • While a metal spudger tool is shown here, it is best to use a plastic spudger / opening tool when possible, and only use a metal spudger as a last resort!

Conclusion

To reassemble your device, follow these instructions in reverse order.
