● If you recently installed new software, uninstall the software to see whether the workstation
functions properly.
● If the internal display panel on an all-in-one computer is blank, open the computer and be sure that
both ends of the cable between the system board and the internal display panel are connected. If
you are using a graphics card, verify that the 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.
