display brightness and resolution
QMy display is blank. What’s wrong?
AIt 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.
QCharacters are garbled or the display flashes when the notebook is connected to an external TV. What’s wrong?
AThe 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.
