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
) 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”).
