Palm's posted an upgrade for the Treo 800w, available from Sprint in the U.S. The battery charging software update, which Palm highly recommends, is designed to address the following:
USB
If your device fails to detect any of the in-box USB accessories such as the power adapter, headset or sync cable, this update will resolve most of the detection issues.
Battery charging
When plugged into the charger, the device may not charge a completely discharged battery. This scenario is most likely to happen if you leave a dead battery for a few days before trying to charge it in the device.
Palm adds:
If the device will not turn on to install the update, you should "trickle charge" the battery by connecting your device to a PC via the USB sync cable. The device will charge slowly by using the PC's power. When the device's battery indicator shows 25% charged, you can proceed to install the update.
As with any such update, make sure to back up all your data before proceeding. See here to obtain the software upgrade and find out how to install it.
This upgrade follows
one released a little over a month ago to bring support for voice dialing over Bluetooth on to the Windows Mobile-run Treo; a great feature to have for a device with Bluetooth 2.0, which makes the smartphone compatible with any number of wireless headsets and car kits for hands-free calling.
