Troubleshooting
If you have a problem with your Zaurus, check the following points.
If the problem remains, contact our Support center.
The screen is dark.
I want to know how to turn the back light on.
• Adjust the brightness of the light setting in the Light & Power application (See the
Operation Manual: “Managing power (Light & Power)”).
• Is the back light turned on? When the back light has been turned off due to the
power saving setting of the Light & Power application, press the Back light key to
turn the light on.
The charge light blinks or will not turn on.
• When the battery has been fully charged, charging the battery is unnecessary and
the charge light will turn off. Tap the battery icon to check the battery status.
• Make sure that the supplied “EA-70” AC adapter is used and connected correctly.
Disconnect the AC adapter and then connect it again.
• Remove and reinsert the battery. Make sure that the battery replacement switch
is set to the “ ” (see page 8).
• If the error persists, the battery or the unit may have a problem. Contact your local
SHARP dealer for repair.
The Zaurus does not turn on even after recharging.
The charge light does not turn off even though more than standard
charging time has elapsed since the charging began.
• When the battery has not been used for an extended period and has become
overly discharged (including the first use of a new one), the power may not turn
on for several minutes after charging and the charge light may not turn off even
after the standard charging time. In such cases, disconnect the AC adapter and
remove the battery. After approximately 5 seconds, replace the battery and
recharge the battery (see page 90).
• Charge at the specified temperature range: 5°C to 35°C (41°F to 95°F).
• If left unattended after charging is completed and the charge light has turned off,
the battery may discharge and charging may restart.
The Zaurus turns off by itself.
• You have not operated the Zaurus for a certain period and the Auto power off
function may be activated. Press the POWER key to turn the Zaurus on again
(see page 33).
