12C Case Opening


I have just opened my vintage HP12C case to attempt to clean the contacts, etc. to hopefully resolve an intermittent display issue (I have to press the case to have the display come on).

However.... when removing the back case, a very small spring popped out, and I'm unsure of its location. Any help as to replacing it would be appreciated.



You may find your unit looks a bit different inside but there are always two springs in the same location across all Voyager models and versions.
