I need to replace the battery
Contact Palm or AT&T to get your smartphone repaired. Within the
warranty period, your battery should not need replacing. With good
treatment, your battery is likely to last for a couple of years. See Maximizing
battery life for helpful tips.
Screen and performance
The screen appears blank
If you hold the smartphone up to your ear while on a call, the screen goes
dark. This is normal behavior. It prevents your accidentally tapping an item
on the screen and saves battery power. When you take the smartphone
away from your ear, the screen automatically turns back on, ready for use. If
the screen doesn’t turn on fast enough for you, tap the screen to wake it up.
The same behavior occurs anytime you’re on a call and the smartphone
screen is placed near another surface. The screen turns on automatically (if
the smartphone is still on) when you move the smartphone away from the
other surface.
When the smartphone is on and idle, the screen first dims and then turns off.
This also is normal behavior, caused by the auto shut-off interval. You can
adjust this auto shut-off interval to be as long as three minutes (see Set the
interval for turning the screen off automatically). At first, the screen dims as
a power-saving measure. Just tap the screen to brighten it. Then, if your
smartphone remains inactive for the full interval you set, the screen turns
itself off. Press power to turn the screen back on.
Follow these steps in sequence if you can’t turn the screen back on:
1 Make sure you have removed the protective cover that came attached
to your smartphone screen.
2 Make sure that there are no stickers covering any part of the front of
the smartphone.
3 To brighten the screen if it has dimmed, tap the screen.
4 To turn on the screen, do one of the following:
• Press power . Drag up to unlock the screen.
• Slide out the keyboard.
• If the keyboard is out, press any key.
5 Look closely at the screen. If the display appears but is faint, try
adjusting the screen brightness (see Change screen brightness).
6 If the problem persists, connect your smartphone to the AC charger
(see Charge the battery). If you see a faint display, try to restart your
smartphone (see Restart your smartphone).
7 If you don’t see a display or the screen doesn’t respond to taps, press
and hold power and slide the ringer switch three times to
restart your smartphone. Then wait until your smartphone completes
startup.
An application is not responding to taps
1 Make sure you have removed the screen protector that came attached
to your smartphone screen.
