I've replaced the HDD in a laptop, and while doing that I needed to disconnect several flat cables. Notably, the one for the trackpad is now causing problems.
The photo below is from the iFixit guide I followed and it shows several connectors (cream-white) and their locking tabs (black). The one being worked on is the touchpad.
That little black lock bar broke! So when reassembling, I can easily slide the flat cable into the connector but now there's nothing to push down on the connector to ensure a solid contact.
Note that this connector is similar to this schematic, where the cable (with the copper contacts facing down) is loosely pushed into a slot and then secured by closing a hinged lid from above.
Inserting the cable is no problem, but without the lid it only fits loosely, so there is no connection.
I can't physically remove and replace this connector. How can I repair this? I guess I need some method of pressing the cable down onto the connector's terminals.
