Wake the computer by pressing any key on the keyboard or pressing
the power button. If the system remains in suspend mode for more
than four seconds, shut down the computer by pressing and holding
the power button for at least four seconds then press the power button
again to restart the computer. If the system will not shut down, unplug
the power cord, wait a few seconds, then plug it in again. The computer
will restart if automatic start on power loss is set in Computer Setup.
If it does not restart, press the power button to start the computer.
Reconfigure your computer after installing a non–plug and play
expansion board or other option.
Be sure that all the needed device drivers have been installed. For
example, if you are using a printer, you need a driver for that model
printer.
Remove all bootable media (diskette, CD, or USB device) from the
system before turning it on.
If you have installed an operating system other than the factory-
installed operating system, check to be sure that it is supported on the
system.
If the system has multiple video sources (embedded, PCI, or PCI-
Express adapters) installed and a single monitor, the monitor must be
plugged into the monitor connector on the source selected as the
primary VGA adapter. During boot, the other monitor connectors are
disabled and if the monitor is connected into these ports, the monitor
will not function. You can select which source will be the default VGA
source in Computer Setup.
CAUTION:
source, there is always voltage applied to the system board. You
must disconnect the power cord from the power source before
opening the computer to prevent system board or component
damage.
