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 HPÊJornada 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 resetÑA soft reset (also called Òwarm bootÓ) is similar to restarting your desktop PC. It restarts the operating system and preserves any saved data.

¥Full resetÑA full reset (also called Òhard resetÓ) re- stores your HP Jornada to its original state, erasing all information you have entered.
