Introduction

The WiFi module is the primary method for wireless network connectivity. If this module shows symptoms of malfunction, a USB-to-Ethernet cable adapter can be used to maintain network access until the module is replaced.

  • Lift the keyboard up, then pivot it towards you to lay it facedown on the trackpad and palm rests.

My keyboard was also stuck down with double sided tape near the sides 1cm down from the top edge. These didn't want to let go easily, be careful pulling them away.

Also, on my keyboard there are metal latches under the keyboard. To remove the keyboard it needs to be slid towards the screen a few mm before you can lift it. When reassembling do the reverse, engaging the latches, or the keyboard will not stay down properly.

  • Locate the ribbon cable connecting the keyboard to the motherboard.

  • Use the tip of the opening tool to lift the black flap on the connector.

  • With the twezers, gently lift the ribbon cable out of the connector.

  • Be careful when reinserting the ribbon cable.

    • Ensure the cutouts on the end of the cable match the tabs on the connector.

The cable is not lifted . It should be pulled parallel to the line of the memory chips. The Lenovo service guide makes this clear.

Getting the cable back i was tricky. in the end I almost had the keyboard vertical to east the bend on the connector as I pushed it back in gently - then it finally went in. When you push the retaining flap back down the white line on the ribbon cable should just be showing - then you have it in properly.

Image 1/1: Two 3 mm Phillips screws
  • Locate and remove the screws holding the bezel to the laptop body:

    • Two 3 mm Phillips screws

    • Three 5.5 mm Phillips screws

I found my Nextek (+) 2.0 x 40mm fitted these well. PH000 wasn't bad but not quite the right fit

  • There is now nothing securing the bezel to the laptop body. However, there are still two cables connecting the bezel to the mainboard. Ensure the bezel remains in place until the cables are disconnected.

  • Flip the laptop back over.

  • Locate the small trackpad ribbon cable and use the opening tool to lift the black flap on the connector.

  • With tweezers, gently pull the ribbon cable out of the connector.

    • You can use the clear plastic tab on the top of the ribbon connector to help pull the cable out.

Again pull the ribbon cable parallel to the circuit board not up away from it.

  • Locate the power board cable and disconnect it by pulling the cable head towards the front of the laptop.

    • Be careful to not damage the socket.

I found it hard to get anything into the gap until I used a modelling knife set's pointer. I could ease this very gently into the gap which then created a narrow space i could use to ease the connector out. As staetd above take extreme care to use only light force so as not to damage the cable or socket. again the direction to ease it out is parallel to the circuit board.

  • Lift the keyboard bezel off the laptop.

There are clips around the edge of the bezel so it does not just lift off. I used a thin plastic store card to go right around the edge to ease the bezel away. You could use your plastic opening tool from step 1, but I used store cards for that step too as I don't have a plastic opening tool.

  • Unplug the battery cable.

This proved anything but easy. The connector just wouldn't disengage. I had a good look atb the new battery and decided that the best place to push was with a small flatblade screwdriver from the gap suspiciously ;) deliberately provided in the battery in the direction of the WIFI board. It then came out fairly easily. It feels like Lenovo engineers may have a specific tool for this.

Best fit for these screws was a Philips PH000 screwdriver bit

I took the opportunity to clean out the dusty fans with pressurised gas duster before putting it all back together.
