I recently spilled a little bit of water on my Acer Aspire 5740. I quickly took the battery out, checked the hard drive, and turned it over so any water in the keyboard could drip out. When I put it back together, it seemed to be working fine until I found that certain keys failed to work. I decided to replace the keyboard. While disconnecting the cable, a skinny black piece came out as well, maybe it's the part called the cable lock? It's hard for me to describe, but it fit into the computer, and now it's been misplaced. Is this something that can be fixed with a new part? I cannot find any information about this.
