• Press and hold any key. If the system beeps, then your keyboard is operating correctly.
• Check all cable connections for loose connections or incorrect connections.
• Wake the workstation by pressing any key on the keyboard or the power button. If the system remains in suspend
mode, shut down the system by pressing and holding the power button for at least four seconds, then press the
power button again to restart the system. If the system will not shut down, unplug the power cord, wait a few
seconds, then plug it in again. If it does not restart automatically, press the power button to start the workstation.
• Reconfigure your workstation after installing a non–plug and play expansion board or other option. See section
5.4.2 "Hardware Installation Problems" for instructions.
• Be sure that all the needed device drivers have been installed. For example, if you have connected a printer, you
need to install a printer driver.
• If you are working on a network, plug another workstation with a different cable into the network connection.
There may be a problem with the network plug or cable.
• If you recently added new hardware, remove the hardware and see if the workstation functions properly.
• If you recently installed new software, uninstall the software and see if the workstation functions properly.
• If the screen is blank, plug the monitor into a different video port on the workstation if one is available. Or,
change out the monitor with a monitor that you know is working properly.
• Upgrade the BIOS. A new release of the BIOS could have been released that supports new features or fixes your
problem.
• For more detailed information, refer to the troubleshooting chapter in the Service and Technical Reference Guide
