Backlight Info
The Backlight Info window shows the elapsed time of usage for the
light behind the display screen. The expected lifespan of the
backlight is approximately 30,000 to 40,000 hours. At some point
after the maximum usage time of the backlight has been exceeded,
you may notice a decrease in brightness of up to 50%. At this point,
the backlight needs to be replaced to restore full brightness.
CAUTION: The backlight can be replaced only by a trained
technician. Please contact the HP Support Center
for assistance. Do not attempt to replace the
light yourself.
NOTE: Do not use a screen saver with the LCD monitor, as the
backlight will be used. It is recommended that you enable
an automatic power saving mode, or switch off the monitor
when not in use.
