A hard reset will erase all current data on the device. This should only be done if a soft reset has not solved your problem.

A hard reset is done by simultaneously holding down the power button while also pressing the reset button on the back with a paper clip like you did for the soft reset. After a few seconds the Palm logo should appear, when it does, release the power button.

If applicable, you can restore any data previously synchronized with your PC through the HotSync operation of the device.
