Frequently-asked questions
The following is a list of possible situations that may arise during the
use of your computer. Easy answers and solutions are provided for
each one.
I pressed the power button
and opened the display, but the
computer does not start or boot-up.
Look at the Power indicator:
• If it is not lit, no power is being applied to the computer. Check
the following:
• If you are running on battery power, it may be low and unable
to power the computer. Connect the AC adapter to recharge
the battery pack.
• Make sure that the AC adapter is plugged in properly to the
computer and to the power outlet.
• If it is lit, check the following:
• Is a non-bootable (non-system) diskette in the external USB
floppy drive? Remove or replace it with a system diskette and
press Ctrl-Alt-Del to restart the system.
Nothing appears on the screen.
The computer’s power management system automatically blanks the
screen to save power. Press any key to turn the display back on.
If pressing a key does not turn the display back on, three things might
be the cause:
• The brightness level might be too low. Press Fn- ↑ (increase) to
adjust the brightness level.
• The display device might be set to an external monitor. Press the
display toggle hot key Fn-F5 to toggle the display back to the
computer.
• If the Sleep indicator is lit, the computer is in Sleep mode. Press
and release the power button to resume.
