The voltage regulator on your Palm Treo smartphone is a small electronic component that is attached to the main circuit board of the unit. If you have been having problems charging your Treo, a glitch in the regulator likely is the cause. This can be fixed by performing a factory reset on your Treo, which will reset the regulator.
Instructions
1. Turn off your Palm Treo and slide the battery door off the rear of the unit.
2. Press the "Power/End" key on the Treo's keypad and hold it down.
3. Remove the battery while holding down the "Power/End" key and immediately reinsert it.
4. Continue to hold the "Power/End" button until the "Palm Powered" logo screen appears. Release the button when you see this screen.
5. Press the "Up" key when prompted to confirm the factory reset. Once you do, this the screen will go blank.
6. Remove the battery, put it back in and press the "Power/End" button to restart the phone. The phone, as well as the voltage regulator, will now be reset.
