RE: Dell t5500 workstation diagnostics lights 2 3 4 blinking no display
Hi i have some success.
I removed processor from onboard socket and installed riser card with processor. And surprisingly I got display but the fans were still running full speed.
And the dell bios gave error that fan on cpu 2 is not working..
Whereas it was working and i took this riser card from a working system. I reconnected the riser card ram fans connector. Still same. Rest bios still it gives error message.
