Looking to purchase a Lenovo x220 on ebay, but its keyboard connector attached to the motherboard is damaged. Anyone know a way to replace or fix this part?

A workaround would be to just use a USB keyboard.  That would be my preferred choice.

I did not say that...I was just pointing out what I considered obvious...I prefer to use USB mouse and keyboard with my laptop.

 

Hold on for suggestions from others :).

If the connection between the connector and motherboard is broken then you would need an external keyboard. Sometimes a broken connection at the motherboard can prevent a computer from booting. If it's only the part of the connector that rotates and locks the ribbon cable to the connector sometimes a small plastic shim can be placed between the ribbon and the connector to keep it in place.

doing component level repairs myself, this is what would have to happen.

it can be fixed!  - but not by yourself.  you need an expert that knows what he is doing.

 

and then whether you can find the connector is another problem.  most of the time you have to buy a dead donor board and remove the connectors from both boards and

install the donor connector on the working board.  While in the mean time hoping you don't over heat and destroy the donor connector while removing it.

 

it can be done, but finding someone that does that repair is difficult.

 

sometimes it's just cheaper to buy a working used motherboard off ebay and swap them out.

I must have missed it, exactly what manufacturer and model is this computer?

I ask because years ago as a roaming replace-parts tech who had broken the keyboard/motherboard connection, I was able to purchase a used internal keyboard that included that very important part -- however, be aware it costs me $140.00 (I had to have one within 2 hours, there was no time for Amazon or Ebay hunting).  If you have to have an internal keyboard, shop around, ensure it comes with that important connector, although, you are much better off with a usb keyboard and mouse kit as others have posted.

Hm. Interesting... However, it was indicated by the seller that "one of the metal pieces, motherboard side, has broken off." Besides that, how effective would this fix be?

If it was just the plastic locking clamp that broken then using a plastic shim is effective but having a metal piece of the connector broken from the motherboard does not sound good. In that case I doubt the plastic shim will help.

Just based on the description offered you would likely have to desolder the existing keyboard connector and resolder a new one.  If it's just a broken solder joint you could try simply resoldering the joint.

 

The above being said, looking on eBay, the motherboards for these machines are not expensive.  If I had to tear down the machine to get to this part for the fix I'd be far more inclined to buy a new motherboard than to try to fix the existing one if the issue was not a simple broken solder joint.
