I have a dell inspiron M5030 that has a black screen. I have tested the memory, put new memory in, drained the power and restarted several times, and finally I have checked the connections for the screen. When I boot the system I get a black screen with a 7 beep warning buzzer.
I have also tried using a separate monitor with no luck.
If anything I would like to know what 7 buzzer beeps are... thank you:)
