Chapter 14 : Troubleshooting 187
T4. Top up the battery
1 Connect the USB cable to the AC charger and to your smartphone.
2 Plug the AC charger into a working electrical socket.
3 Let the battery charge completely.
Why this might help
Fully charging the battery ensures your smartphone is not conserving
power due to a low battery.
NOTE If you use an HP Touchstone, make sure you complete T4 using the USB
cable and the AC charger, not the Touchstone. Connecting directly to an outlet
is more effective in waking a smartphone.
T5. Take out the battery
1 Try shutting down the smartphone: Press and hold the power button.
Tap Power > Shut Down/Swap Battery > Shut Down.
2 Whether step 1 succeeded or not, take out the battery, wait 10
seconds and then reinsert it (see I need to replace the battery). This
causes your smartphone to restart.
Why this might help
Reinserting the battery performs a restart and also triggers an automatic
clean-up of files that weren't closed properly.
NOTE Because open applications are forced to close immediately during this
kind of restart, some unsaved data may be lost.
T6. Tether your smartphone to your computer and reinstall
webOS
IMPORTANT Don't try this method until you've already tried the five Ts before
this.
1 On your computer's web browser, go to hpwebos.com/account,
sign in and write down your smartphone's serial number.
2 Go to hpwebos.com/rom and click the link to get webOS Doctor.
3 Enter your serial number and follow the instructions.
Why this might help
Installing the latest version of webOS wipes and refreshes all memory.
Your preferences and installed software are not affected.
Want help while you use webOS Doctor? Go to hpwebos.com/support.
Select your smartphone and wireless service provider and click Support
Services. Select one of the support options.
