I'd see what you can do from the rear first. The ring with the name on at the front is glued with a few spots of contact adhesive. It can be forced off easy enough, but needs careful gluing back to avoid glue on the front element.

There's also an adjustable element at the front held by black tape. It can be rotated to set infinity properly and taped back up.

You shouldn't remove the battery
It's still holding your cmos/bios settings.... if you remove
it all will be lost and you will need the motherboard manual
to reset some of them such as CPU speed.

Try to read it in the machine with a magnifying glass
if need be. It might be in the manual.

It's probably a CR2032 or Cr2025 .... 20 is the diam.
32 is the thickness = 3.2mm etc. Readily available even
in some supermarkets.

Quickly swap the new battery over.

Here's a set of pics that might help showing how to repair the lens: link

That link came from Ricehigh's site link

This one might be a bit clearer:

Don't you mean electrical

Nice powerful image.... did you not know what the prize
was before you entered

Was the 2nd prize TWO Canon cameras

Great shots... the light looks like sunlight!

That's tough!...... Is it not still under guarantee?
In any case I would expect a free repair, because you
wouldn't expect a pro lens to break like that

There is a Notification from Ricoh's Dept. of Notification about the Thailand flooding here:

Only seems to effect the GXR MOUNT A12

Just remembered the GS heater, because it was an air-cooled engine consisted of a ball welded into the exhaust with a 4inch diam. flexipipe that went into the car..... smelt a bit as well I bought my GS off a very famous pop star, think he used it for shopping

The Alfasud was designed in Italy and so was the heater, probably when the air temp was 40deg C they must have thought..... any hotter than that and people will roast to death When it came over here there was more heat out of a peppermint in one of our winters
