Hi All , I have a problem with my machine , it has a no display problem, and intermittently the green power light comes on, and the data light lights up. The mainboard assembly was replaced but the issue still occurs, Tried to install the firmware but unable to communicate to the board to do so through the default ip.The firmware cannot be installed without successful commuinication. Can anyone assist with this problem? Is it the memory module that is bad ? or another board thats causing the issue?
