Display Problems - HP omnibook OBXT1500 Reference Manual

If the notebook cannot read a CD or DVD
• For a single-sided CD or DVD, make sure the disk is placed in the drive with the label
facing up.
• Clean the disk.
• Wait 5 to 10 seconds after closing the tray for the notebook to recognize the disk.
• Remove the disk from the drive, then restart the notebook.
• If you created the CD on a CD-RW drive module, try using a different media brand,
such as the recommended HP C4403A (CD-R) or C4404A (CD-RW) media. Read
and write quality may vary for other media.
If a DVD movie doesn't fill the screen
• Each side of a double-sided DVD has a different format (standard or widescreen). In
widescreen format, black bands appear at the top and bottom of the screen. To view
the standard format, flip the disk over and play the other side.
If a DVD doesn't play with two displays
• If both displays are active, press Fn+F5 to switch to one display.
• If you're using both displays, the DVD image will not appear on any display set up as
"secondary". Click Start, Control Panel, Appearance and Themes, Display. Click
Advanced on the Settings tab, then click the S3Display tab and change settings.

Display problems

If the notebook is on, but the screen is blank
• Move the mouse or tap the touch pad or scroll pad. This will wake the display if it is
off.
•
Try pressing Fn+F2 to increase the display brightness.
• Press Fn+F5 in case the internal display was disabled. (Do this three times to return to
the state you started from.)
• If the notebook is cold, allow it to warm up.
