CHAPTER 5: TROUBLESHOOTING

Basic Hints and Tips
• Computer does not power on: Is your AC adapter cable securely connected to a working
electrical outlet? If connected to a power strip, ensure that the strip is actually working.
• Connections: Check all the cables to ensure that there are no loose connections
anywhere.
• Power Savings: Ensure that your computer is not in hibernate or standby mode by
pressing the power button for less than 4 seconds. The power status light will fade from
blue to black while in standby mode; in hibernate mode it will be off.
• Brightness: Check and adjust the brightness of the display by pressing the key
combinations <Fn><F4> or <Fn><F5>.
• Display Choice: Press the key combination <Fn><F1> to ensure that the computer is not
set to “External Only” display.
• Use only the AC adapter that shipped with your laptop.
