The Palm TX has a rechargeable battery that can be charged two ways:
- With included AC power adapter
- Through the USB sync connector, also known as a "trickle charge"
Depending on the computer system, the trickle charge can occur at 100mA or 500mA. Some systems, such as laptops, may not support trickle-charging at all.
We recommend using the power adapter to recharge the Palm TX handheld. It takes three hours to fully charge the handheld using the power adapter. The trickle charge method can take nine hours to fully charge the handheld; therefore, this method is generally recommended as a supplemental charging method.
How do I know if the handheld is trickle charging?
If your handheld is receiving the full 500mA charge (through the power adapter or trickle charge), it will beep when plugged in, and it will display a lightning bolt symbol over the battery symbol.
If it is receiving a 100mA trickle charge, the battery symbol will not have the lightning bolt.
