Problems?
If you don’t see anything on your screen or you think your computer did not start up properly, check these items:
mIs the power adapter plugged into a power source? If it is plugged into a power strip, is the power strip turned on? Is the power adapter properly plugged into the computer?
mAre the keyboard and monitor cables connected correctly?
mIs the power button lit on the computer and on the monitor? If not, the computer or monitor aren’t receiving power. If the power button on your computer is pulsing, it means the computer is in sleep. Touch the power button or any key to wake it up.
mAre the brightness and contrast controls on the monitor adjusted correctly? If your monitor has brightness and contrast controls, try adjusting them.
mTry restarting your computer. Touch the power button on the computer for approximately 5 seconds until the computer turns off. Touch it again to turn the computer on.
mIf you see a blinking question mark on the screen or a series of flashes from the computer or display power buttons when you turn on the computer, see Chapter 5, “Troubleshooting,” on page 71.
