The computer display has a native resolution of 1024 x 768 (XGA) for
the 14.1" or 1400 x 1050 (SXGA+) for the 15.0". If you set the
resolution lower than this, the screen expands to fill the computer
display. Right-click on your Windows desktop and select Properties to
bring up the Display Properties dialog box. Then click on the
Settings tab to make sure that the resolution is set to the appropriate
resolution. Resolutions lower than the specified resolution are not
full-screen on the computer or on an external monitor.
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 on
the icon and deselect the Mute option.
• The speakers may be turned off. Press Fn-F8 to turn the speakers
on (this hot key also turns the speakers off).
• The volume level may be too low. In Windows, look at the volume
control icon on the taskbar. You can also use the volume control
buttons to adjust the volume. See "Hot keys" on page 17 for more
detail.
• If headphones, earphones or external speakers are connected to
the line-out port on the computer's left panel, the internal
speakers automatically turn off.
