Problems turning on your computer?

If the screen is dark, check these items to see if you can identify the problem:

mIs the computer plugged into a power source? If it is plugged into a power strip, is the power strip turned on?

mIs the computer turned on? The power-on light on the front panel should be on. If it isn’t, press the standby power button (marked with the symbol ®) on the back of the computer.

mAre the keyboard and mouse cables connected correctly? (Don’t disconnect the keyboard or mouse cable while the computer is on. You could damage your equipment.)

mIs the monitor power cord plugged in?

mIs the monitor turned on? (Check the power-on light on the front of the monitor.)

mIs the monitor video cable—the one connected to the monitor video port (™) on your computer—attached firmly to both the monitor and computer?

mIs the brightness control on the monitor adjusted correctly? (On most monitors, the brightness control is marked with the symbol ¤.)

If you see a blinking question mark on the screen, turn to “Solutions to Common Problems With Your Computer” in Chapter 6.
