Any Sock KAL 2

I wonder if I could get just that little piece replaced... but I'm guessing not.

If it is the end of the power cord this can be replaced. Most electronic parts stores (like RadioShack) will have the part. If it is the part inside the computer . The connection inside the computer is wired to the motherboard and in most cases replaceing the motherboard is easier than replacing this one part.
DSWMBO&OM killed one of her laptops this way. I now use in in place of my desktop that died after about 5 years. I have a rubber band around the plug and laptop to hold it in the correct position. Not pretty but it works.
