Resetting HP Jornada 820e

Occasionally, you will need to reset your HP Jornada; for example, you may reset after you restore data from your
desktop PC or when the operating system stops responding.

There are two methods of resetting:

- Soft reset A soft reset (also called warm boot) is similar to restarting your desktop PC. It restarts the
operating system and preserves any saved data.
- Full reset A full reset (also called hard reset) restores your HP Jornada to its original state, erasing all
information you have entered.

To ensure the safety of your information in case a full reset is necessary, you should regularly back up your data to
your desktop PC (using Windows CE Services) or to a CompactFlash or PC Card (using the HP Jornada backup

Soft reset

Full reset
Perform a full reset only when your HP Jornada does not respond to a soft reset. A full reset will erase all data you
have entered, including all files, system settings, and programs you have installed. If you have forgotten your
password, you will also need to perform a full reset.

Performing a full reset erases all files, programs, and appointments you have entered. You
can restore only data that has been backed up to your desktop PC or to a PC Card or
CompactFlash Card.

1. Disconnect the AC adapter from your HP Jornada.
2. Remove the main battery.
3. Remove the backup battery tray.
4. Wait at least 5 minutes, and then reinstall the batteries and reconnect the AC adapter. Your HP Jornada should turn on automatically, and display the Windows CE Welcome Wizard.

General advice: Before you buy a new cell phone or new tablet, please try the following procedure to repair your device in a software way. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card before doing factory reset. It is impossible to recover your data after doing a hard reset, so online backup is always important. For all of your data, a backup should be done on an external device, hard drive, raid system or media. With or without insurance, if your cell phone lost, damaged or stolen at least your invaluable data is backed up in a safe place. If you are about to sell your phone and you want to wipe your personal data, or if your phone affected with virus you have to do a hard reset. In some cases, you can delete the forgotten password or lock pattern from your device as well. All information is for devices with stock based ROMs. If you are using rooted device, always back up your EFS folder first, containing your IMEI info, etc.! Please also note, that a hard reset operation will not unlock your mobile phone's SIM lock or network lock, but it will remove the unlock pattern, remove the user password or PIN password (NOT the SIM card's 4 digit PIN code). Also note that the firmware version will not be affected in any way, it will not be downgraded, it will remain the same you are using and if you have rooted your device, root privileges remain also unaffected.
