●If you recently installed new software, uninstall the software and verify if the workstation functions properly.

●If the internal display panel on an all-in-one computer is blank, open the computer and ensure that both ends of the cable between the system board and the internal display panel are connected. If using a graphics card, verify that the graphics card is properly installed.

●Upgrade the BIOS. A new release of the BIOS might have been released that supports new features or fixes your problem.
