8 - 2 Basic Hints and Tips

Basic Hints and Tips

Many of the following may seem obvious but they are often the solution to a problem when your computer ap-

pears not to be working.

• Power - Is the computer actually plugged into a working electrical outlet? If plugged into a power strip,

make sure it is actually working. Check the LED Power & Communication Indicators (see “LED & Hot

Key Indicators” on page 1 - 9) to see the computer’s power status.

• Connections - Check all the cables to make sure that there are no loose connections anywhere.

• Power Savings - Make sure that the system is not in Hibernate or Sleep mode by pressing the keys config-

ured in your Power Options, or power button, to wake-up the system.

• Brightness - Check the brightness of the screen by pressing the brightness buttons to adjust the brightness.

• Display Choice - Make sure the system is not set to “external only” display if an external display is

attached.

• Boot Drive - Make sure there are no optical media and/or USB storage devices in any connected drive

when you start up your machine (this is a common cause of the message “Invalid system disk - Replace the

disk, and then press any key” / “Remove disks or other media. Press any key to restart”).
