Unlike the Treo 650, the Treo 680 does not have a reset button under the battery cover. Instead, you will be removing the battery to reset. Read below for details. There are several methods found online, this one seems to be the most “Official”. I will say that it sounds somewhat silly to have to remove the battery to perform this.

HotSync note: Some third-party applications change the way your device backs up data. Other third-party applications do not back up data. If you have third-party software on your device, please contact the developer to learn what components are backed up during a HotSync operation, and if HotSync conduits are altered. Any data not backed up will be lost.

4. While still holding the power button, re-insert the battery, and replace the cover.
5. When the Palm logo appears, release the power button.
6. A message will appear warning that you are about to erase all the data stored on your device. Press UP to complete the hard reset, erasing everything on your device.

A soft reset stops all running applications, but does not erase any
programs or saved data. Be sure to save any unsaved data within a
running application before performing a soft reset.

To perform a soft reset:
1. Locate the recessed Reset button on the bottom of your HP iPAQ.
2. Use the stylus to lightly press the Reset button.
The HP iPAQ restarts and displays the Today screen.

A hard reset stops all running applications, but does not erase any

While boxing up the Cingular 8125 to send to a buddy to use, I was doing a hard reset so he wouldn’t get all my girlfriend’s phone numbers. While doing this hard reset, I remembered how much of a pain it is to accomplish. Since reading how to do it is not that fun, I whipped up a little graphic to illustrate the locations of the buttons you have to hold down. I hope someone can benefit from this post. Enjoy!
