Display
If you are having trouble viewing your data, here are some
suggestions.
Screen is blank
If your HP Jornada fails to respond when you briefly press
the On/Off key, try holding the button down for a full
second. If that does not work:
Make sure your battery cover is locked and all expansion
slots are secured.
Adjust the display contrast. On some devices, the screen
can darken or lighten to the point that it appears to be
turned off.
Reset your HP Jornada. (See the Resetting section in
this chapter.)
Recharge the main battery.
Screen is dark
Prolonged exposure to direct sunlight may cause your
HPJornada screen to temporarily darken. This is a normal
occurrence with LCD screens and is not permanent.
Resetting
Occasionally, you will need to reset your HP Jornada; for
example, you may reset after you restore data from your
desktop PC or when the operating system stops respond-
ing. There are two methods of resetting:
Soft reset—A soft
reset (also called “warm boot”) is
similar to restarting your desktop PC. It restarts the
operating system and preserves any saved data.
Full reset—A full reset (also called “hard reset”) re-
stores your HP Jornada to its original state, erasing all
information you have entered.
