I can't turn on laptop! Power button problem

without clear pictures I cant see to assess the damage. im assuming your using a phone. try turning on the macro setting.

A better image is needed to understand what's been done. Get access to a digital camera and set it for close up and low resolution so it loads easier and re-post pictures.

I'm sorry but I think you're hosed on this one. Unless you're skilled in de-soldering and re-soldering after finding this part.....short of that then it's a new mobo time!

You may very carefully look at the other connector behind the damaged one and see if this connector has two parts that slide or attach making this fitting if so then you'll be on a quest to find that but to my eye it's one part that's not meant to come apart.

Well I'm not saying that, you may be able to rig the thing up somehow but it will for sure be a Macgyver duct tape and bailing wire thing. You could try and should try maybe with a friend to help apply pressure on the flat cable and it that still works then maybe a super glue with weights to hold while dry solution could work but I'm not suggesting it will last long term?

Yes the ribbon cable needs to line up in the fastener which has no top now, so lay it down and have a friend try to start it up with you holding the ribbon cable down. If that works then maybe there's a way, I'm good at this kind of stuff.....mother of invention stuff but zero chance without seeing and touching to know what I'm up against.

Wow! That's like saying I accidently threw a hammer at the TV set. Glue is not going to make a connection. Each wire will need to be stripped and soldered to pins. If it's valuable to you, take it to a service center and have them fix it. Otherwise, you need a new motherboard.
