Troubleshooting

Display

Why did my screen go blank?

❑ Your computer screen may go blank if the computer loses power or enters a power saving mode (Sleep or Hibernate). If

the computer is in LCD (Video) Sleep mode, press any key to bring the computer back into Normal mode. See Using the

Power Saving Modes (page 136) for more information.

❑ Make sure your computer is securely plugged into a power source and turned on. Make sure the power indicator shows

the power is on.

❑ If your computer is using battery power, make sure the battery pack is installed properly and is charged. See Using the

Battery Pack (page 24) for more information.

❑ If the display mode is set to the external display, press the Fn+F7 keys. See Combinations and Functions with the Fn

Key (page 33) for more information.

❑ During the switching process, your computer screen becomes dark and may temporarily show some noise or flicker. This

is normal and does not indicate a malfunction.

What should I do if no image is displayed on my TV screen or external display connected

to the HDMI port?

❑ The HDMI port is disabled when your computer is in STAMINA mode. Change the performance mode to SPEED mode

before connecting an external device to the HDMI port. See Selecting Performance Modes (page 107) for mode

selection.

❑ Make sure you are using an HDCP-compliant display. The copyright protected contents are not displayed on a non-HDCP

compliant display. See Connecting a Computer Display (page 84) for more information.
