Troubleshooting

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 Indicators (see “LED 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 (see “Configuring the Power Buttons” on page 3 - 8), the Fn + F4 key combi-

nation, or power button to wake-up the system.

• Brightness - Check the brightness of the screen by pressing the Fn + F8 and F9 keys to adjust the bright-

ness (see Table 1 - 6, on page 1 - 14).

• Display Choice - Press Fn + F7 to make sure the system is not set to “external only” display.

• 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”).
