Turning the Dell D820 on results in no boot, black screen. Holding the Fn key causes the num lock to blink (left most LED) and the other 2 remain lit.
Can not find an error code on Dell's website or Google. Any thoughts? Is this computer dead?
One time I got it to boot by pressing Fn and it ran that Diagnostic test. Found no errors. Then it says press OK to reboot and I reboot and back to useless black screen and can't even get to the same diagnostics./
Help please
