    • Spot the thin ribbon cable attached to the connector (the connector has a plastic lid).

    • Carefully open the lid with a spudger and slide the ribbon cable out of the connector.

    • Be very gently with the cable and the connector because the lid may come loose. If this happens, it is difficult to put the cable and the connector back in.

    • Close the lid again, after removing the cable, so that the cable cannot jump out.

    • Use a spudge to remove the tape/sticker.

    • Be very gentle and careful with this step because the connector is a hard-to-remove ribbon cable with a bunch of small cables. Ripping one of them will damage the ribbon cable, and will cause bad or no screen.

    • It is recommended to use an IC extractor to remove the LCD connector (however, you can use two small flat-had screwdrivers, or tweezers to slide the connector out o the socket).

    • Remove the golden antenna cable from the socket. Be very careful, and use a spudger.

    • The WiFi module will jump up when the screw is removed. Slide the WiFi module out.

    • Wear gloves to avoid touching the antenna or the antenna sockets.

    • To install the new Wifi module, slide the new WiFi module in , push it down, and put the screw back in.

    • In this case I did not remove the main PCB because then I had to remove the DC jack. It was a very breakable connector, and the wires are very thin. If you break one of them you cannot charge your laptop any more.

    • If the DC jack is damaged or broken in your laptop, remove the hinge instead (this is holding the DC power jack in place).
