If there is nothing on the screen after booting, you are probably experiencing a kernel DRM issue. Support for your Solar System (HD 8xxxM) series graphics hardware has been refined in the 3.13 kernel which was not available in Ubuntu 14.04 "Trusty Tahr" when you reported this bug. Can you retest with the latest Trusty LiveCD and let us know the results?
