DH's Dell Inspiron laptop has been on most of today and in regular use. He left it open and on the floor (but tucked out of sight and reach of little hands - we hope!!). When he came to use it this evening, he found the display had flipped upside down. Cannot find any useful advice on the Dell website, cannot work how it even got updside down, let alone how to flip it back the right way.
Any ideas what we can do?
