Came back to my laptop after 10 mins to find a Blue screen and a message telling me to restart, on doing so it’s saying “no boot device found”, any ideas?

It’s ****?

HD moved? They’ll be a panel somewhere for it removed that and make sure the HD is sitting properly.

Just run a diagnostics on start up and it says ‘no hard drive detected’, WTF?

Sounds like HD failure. Worth checking connections.

and suddenly it works again?!? ran diagnostics for the third time following a gentle bang on the side and she came alive, guessing a connection is loose somewhere; thanks for all your help
