Frequently asked questions
The following is a list of possible situations that may arise during the use
of your computer. Easy solutions are provided for each one.
I turned on the power, but the computer does not start or boot up
Look at the power indicator:
• If it is not lit, no power is being supplied to the computer. Check the
following:
• If you are using on the battery, 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 properly plugged into the computer
and to the power outlet.
• If it is lit, check the following:
• Is a disc in the optical drive? Remove it and press <Ctrl> + <Alt> +
<Del> to restart the system.
• Do you have a USB storage device (USB disk or smartphone)
plugged into your computer? Unplug it 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 hotkey <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.
No audio is heard from the computer
Check the following:
• The volume may be muted. In Windows, look at the volume control
(speaker) icon on the taskbar. If it is crossed-out, click the icon and
deselect the Mute all option.
