How to fix broken keyboard connector

In this guide I explains how to fix a broken keyboard connector on a laptop motherboard.

The connector is a very delicate mechanism. It’s very easy to get it damaged if you apply too much force while trying to unlock it.
The cable retainer (locking clip) is made of thin plastic and if it’s damaged, you are in trouble. Unfortunately, this part is not sold separately.
Well… let’s say it happened. The damage is done. How to fix it now?

On the picture below I show one of the most common connector types. It has the base (white in my case) and cable retainer (brown in my case).
When the connector is closed, the cable secured between the retainer and base.
The retainer applies some pressure on the cable and it makes contact with the pins inside the connector.
To unlock it properly, you have to move the retainer about 2 millimeters in the direction shown by two yellow arrows.
IMPORTANT! The retainer must remain attached base.
After that you can pull the keyboard cable and remove the keyboard.

If you are not careful enough, you can move the retainer too far and break it.
On the picture below you can see the retainer broken on both sides. It is missing the both locking hook.

IMPORTANT! Do not though away the retainer. You still can use it.

The cable will not stay inside the connector without the locking clip.

Here’s how fix this type of damage.
Position the broken piece the way it was inserted before.

Carefully insert the cable into the connector. In this case the cable goes above the retainer.

While holding the cable, carefully push the broken clip back in place. You can use a small screwdriver for that.
The clip fits tightly into the connector even though it has two broken hooks.

Secure the connection with sticky tape and test the keyboard. It should work just fine.

Here’s another connector type. The only difference – the keyboard cable is routed under the locking clip. Fix it the same way as the previous connector.

On the next picture you see another type of connector. The cable is inserted vertically.

In order to unlock the connector, you’ll have to move the locking clip (brown piece) about 2 millimeters up in the direction shown by two yellow arrows.
After that you can pull the keyboard cable (green arrow) and remove the keyboard.

If you move the locking clip too far, you can break it.
In my example one side of the retainer got damaged.

Insert the keyboard cable into the connector, position the broken retainer correctly (behind the cable in my case) and carefully push it in.
Even with a broken retainer the cable should be secured inside the connector.

Here’s the same connector shown from the opposite side. You cannot even tell it is broken.

If this trick worked for you, it means I just saved you big bucks on the motherboard replacement. And I’m glad I did.
REPAIR TIPS FROM READERS:
Thank you to Alex for the following suggestion:
I found another way to fix it…
Have you lost the broken “Locking clip”?
Then do this…
Get some “electrical tape” on the back of the “flat cable” to make some “thickness”.
Make sure you are putting the tape on the right side, where there are no visible connections…
Then very carefully push the cable into the connector… It will not come loose and the keyboard will work just fine!

How to fix hardware problems

In this guide I show how to work around some common laptop hardware problems without taking it apart.
1. Network port failure.
Most motherboards have the network port permanently attached. If the network port fails (I’m talking about hardware, not software failure), the whole motherboard has to be replaced.
Instead of replacing the motherboard, you can use a PCMCIA network card. You plug this card into the available PC slot in your laptop and you are back in business.

If you computer doesn’t have a PC slot, you can use a USB Ethernet adapter instead.

2. USB ports failure.
Most laptops have a few USB ports available. If one of them stops working, usually it’s not a big deal because you still have two or three more working ports left.
But what if all of them stopped working at once? Let’s say the USB controller on the motherboard went bad and the laptop stopped recognizing any device plugged into any USB port. Again, I’m talking about hardware, not software failure. In order to fix this problem you’ll have to replace the motherboard.
Alternatively, you can use a PCMCIA USB card. You plug this card into the PC slot and get two or four USB ports instead. It depends on the type of your PCMCIA card.

3. Internal wireless (Wi-Fi) card failure.
What can you do if the internal wireless card failed?
You can replace the failed wireless card with another one or use a PCMCIA wireless card instead.

4. Internal flash memory card reader failure.
Most newer laptops come with a flash memory card reader. Usually the card reader is soldered directly to the motherboard and if it fails, you have to replace the whole motherboard.
Alternatively, you can use an external USB flash memory card reader. All you have to do is plug the card reader into the available USB port and it’s ready to go.

5. Internal CD/DVD drive failure.
You’ll find an internal CD/DVD optical drive in most computers. If the optical drive failed and stopped reading discs, it has to be replaced with a new one.
Instead of replacing the failed drive, you can use an external USB drive. Simply plug this drive into the USB port, let your computer detect the drive and it’s ready for you.
Also, you can use this optical drive with any other computer which is very convenient.
