One of the issues with the Lenovo laptop is, due to its 360 degree screen rotation, sometimes the connector that attaches the screen to the rest of the laptop can be weakened, damaged, or worn away, causing the screen to flicker intermittently. The assumption is that the screen itself is faulty, but in fact it is the cable that is at fault.
The screen cable isn’t the only connector that will need replacing though. Combined with the screen cable is the Wi-Fi connector and the touchscreen connector. These also needed replacing.
Remove the Base from the Laptop
In order to get access to the motherboard connection of the cable. The plastic base was removed. Unscrewing the screws, and prying it open gently around the edges released the base. Two ribbons also needed to be disconnected, the touchpad and the keyboard ribbon to release the case from the rest of the laptop.
Reveal Screen Screws, Remove them, and Take the Screen Out
For design purposes, this particular model of Lenovo laptop has lots of hidden screws. Removing soft buds, plastic trim (gently removing it by prying it open), reveals a series of screws that need removing to release the screen. This will allow the screen to be gently released, again around the edges using a prying tool, to make the screen pop out, revealing the back of the screen.
Detaching the Screen Cable and the Other Connectors
I disconnected the cable from the Motherboard, gently pulling the cable out of the plastic holders designed to hold the cable in place. I then disconnected the cable from the back of the monitor and touchscreen board, before disconnecting the wireless cable at the top of the screen.
Finally, the cable was pulled through the gap between the screen and the main laptop unit, with a rubber protector also be released to protect the cable in the hinges.
Installing the New Cable – Starting with the Motherboard Connection
With the old cable released, I could then attach the new one. First, I connected the cable to the motherboard, making sure to gently push the ribbon into the section around the fan designed to house the ribbon. This nicely fed the cable to near the hinge, so I fed the remainder of the cable up through the laptop to the back of the laptop screen.
Connecting the Cable to the Other Components
Luckily, all of the connections of the other end of the cable where all different, so it was quite straight forward to connect them to the correct boards and screen, securing them all in place with the included tape.
Feeding the Cable Around into its Housing
With all the ends of the cable connected to the various components, I then spent some time gently feeding the cable, particularly the wireless cable which was rather long and thin, into its housing around the edge of the screen.
Reattaching the Screen and Plastic Protectors
To help keep things tidy, the next step was to reposition the screen and screw it into place. I then reattached the plastic trims, ensuring the screen cable was just next to the hinge, with enough slack to slightly adjust it.
Reattaching the Rubber Protector to the Hinge
The next part I had to be very gentle. Using a set of tweezers I placed the rubber hinge protector around the screen cable, and using a small amount of force, squeezed the rubber into the opening on the side of the hinge. This fitted very snuggly, and ensured the cable was safely stored away to prevent damage. I then finished attaching the remainder of the screen trim.
Putting the Base on the Laptop Back on
Finally, aligning the plastic base, attaching the keyboard and touch pad ribbons, and gently pushing down on the case, it clipped back into place. I then secured it with the screws.
Switching on the laptop, it worked, and I spent some time moving it forwards and backwards to check the screen didn’t flicker any more, leaving it for a bit, and then trying it again. After 1 hour of tilting I was satisfied the issue was resolved, and the laptop was ready to be used again.
