My SONY VAIO MULTI-FLIP 14A is great and no problems for 3 years until today when the LOCK/RELEASE switch to turn it into TABLET is STUCK. It wont move. Any suggestions?

it seems that it is jammed so go to the source, in other words you would have to take apart (at least partly), as the laptop isn’t the most popular you might have to look at a teardown of a different device in the same series though.
