Loose clip in HP Pavilion G6 laptop?

Here is a shot of the C-chaped metal clip that appears to have short-circuited the top SODIMM memory module in our HP Pavilion G6 laptop, giving my daughter a nasty fright:



HP engineers don't recognise the shape of the clip, so suggested that it must have been put there by the retailer (who fitted the extra SODIMM at time of purchase, 11 months back). I didn't watch carefully, but they fitted it pretty quickly and with no apparent problems, so it would be surprising if they had felt it necessary to insert a non-HP metal clip when the two metal arms would have held the SODIMM in place in the normal way.

I'm posting this in case anyone else has a similar problem (in our case: melted plastic cover, smoke, but no flames) and might happen upon this posting. If someone were the second person to find an identically-shaped metal clip floating around inside their HP laptop, then it might persuade HP to check again to see whether this wasn't (as seems the least unlikely solution) a component of theirs that had come loose and come to rest in a location where it did damage, rather than a foreign body introduced by person unkown!

Do get in touch if you are that second person.
