display brightness and resolution
Q My display is blank. What’s wrong?
A It could be several things:
❂ Your notebook may be “Sleeping.”
Press any key to “wake” the notebook from Sleep mode.
❂ The brightness setting may be down too low.
Press Fn + F8 several times to increase the brightness of the display.
❂ Your notebook may be sending its display to an external monitor or TV.
Press Fn + F4 several times to toggle through the attached display, an
external monitor or TV, or both.
❂ Your notebook may be “Hibernating.”
Press the Power button once to resume from Hibernate mode.
❂ The lid switch may be stuck.
Press the lid switch button (located on the keyboard above the function
keys near the base of the display) several times to release it.
Q Characters are garbled or the display flashes when the notebook is
connected to an external TV. What’s wrong?
A The external monitor’s resolution is set too high for your notebook.
See “enabling TV output” in chapter 3 for more information about using an
external monitor or TV.
