This is a discussion on hard reset within the Pocket PC forums, part of the Pocket PCs/Handhelds category; does anyone know how to hard reset my hp1945?...
Just hold down the power on button and push the stylus tip in to the reset hole located on the left hand edge of the unit. The display image will fade and your unit will now be restored to the original factory settings. Also any data you may have in the iPAQ File Store is not lost.
