1.4 Troubleshooting your system after first install
1.4.1 Helpful hints
If you encounter some minor problems with the computer, monitor, or software, see the following list of general suggestions before
taking further action :
•
Check that the computer and monitor are plugged into a working electrical outlet.
•
When available check to see if power supply button is switched on.
•
Check to see that the computer is turned on and the power light is on.
•
Check to see that the monitor is turned on and the monitor light is on.
•
Turn up the brightness and contrast controls of the monitor if the monitor is dim.
•
Press and hold any key. If the system beeps, then the keyboard should be operating correctly.
•
Check all cable connections for loose connections or incorrect connections.
•
Wake the computer by pressing any key on the keyboard or pressing the power button. If the system remains in suspend
mode, 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, and then
plug it in again. The computer will restart if automatic start on power loss is set in the BIOS. If it does not restart, press the
power button to start the computer.
•
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 of printer.
•
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 and PCI Express x16 adapters) and a single monitor, the monitor must
be plugged into one of the three video connectors of the system, i.e. DisplayPort or HDMI. Your system can support three
independent monitors using any of the three available video connectors. If a PCI Express x16 video controller is added, then
the system will support a fourth monitor connected to any of the ports of the video controller. This type of configuration will
require adjustments to the BIOS parameters.
