Motorola ES400 – How to Power Down and Reset
The Motorola ES400 is a great little semi rugged PDA and there are a few ways to reset the device, all with increasing severity. We list them all here:
Hibernate (Unattended Mode)
To put the device to sleep, simply press the power button. This puts the device into a very low state
unattended mode that is very close to being totally off in terms of power usage.
Power Down
To turn off the ES400, simply press and hold the power button until you see the screen to the left. Press the “Power Off” button on the screen when and the ES400 will be totally powered down as if the battery had been taken out.
Soft Reset
Press the power button and the 1 and 9 keys on the keypad and hold them all down at the same time. The device will soft reset itself which deals with any glitches or application running issues
you might have. A soft rest does not delete or reset any of the device’s settings or installed applications, think of it as rebooting your laptop.
You’ll know if the device is soft rebooting because the Motorola Boot screen will have “OSReboot!” in tiny words near the bottom of the screen.
How Do I Perform a Hard (“Full”) Reset?
Perform a hard reset when you want to clear all settings, programs, and data from RAM (Random Access Memory), where data and programs you have loaded are stored. If the battery installed in your iPAQ Pocket PC discharges completely, your Pocket PC will operate as if a hard reset had been performed once the battery has been recharged.
CAUTION: If you perform a hard reset, your iPAQ Pocket PC returns to its default settings and loses all information (files, settings, etc.) that is not recorded in ROM. Information stored in iPAQ File Store will not be lost. For more information on using iPAQ File Store, refer to Chapter 4, “Using the iPAQ File Store Folder,” in the User’s Guide located on the Companion CD.
To perform a hard reset:
- Press and hold the Calendar and iTask buttons.
- While holding these buttons, use the stylus to lightly press the Reset button on the bottom of the iPAQ Pocket PC for about two seconds.
- When the Pocket PC screen begins to fade, release the Calendar and iTask buttons first, and then remove the stylus from the Reset button.
- The Pocket PC resets and powers on.
CAUTION: If you push and hold the Reset button for more than two seconds, the battery disconnects. To restart the
unit, either plug the unit into the AC Adapter or press the Reset button again.
Restoring the Read9 Software to the Dell Axim®PDA
The Dell PDA stores some software in volatile (non-permanent) computer memory. This type of memory requires a very low power level to maintain the stored software. When power is shut off to the PDA, it goes into “sleep mode” and will retain the Read9 software for months, as long as the battery is fully charged when you power down the PDA. However, the Read9 software and accompanying data files may be lost if the PDA is unused for long periods or the battery is allowed to drain completely. Note that the DA battery will drain more quickly if the unit it
stored in a cold area.
P
Hamar Laser installs an SD (Secure Digital) memory card containing the Read9 installation files in every Dell PDA. In addition, some models are supplied with a Factory Backup performed with the built-in data backup utility (not all models and operating systems provide this backup method). The SD card memory is permanent (nonvolatile) and will not be erased if the PDA battery is allowed to drain completely.
The restore method varies depending on the Dell PDA model and the revision of the Microsoft Operating System.
Use one of the following methods to return the PDA to the factory installation level.
Method 1 – Restoring the Read9 Software Using the Data Backup Utility
-
- Click Programs from the top-level menu.
- Click Data Backup to open the backup/restore utility.
- Click on the Restore tab located on the lower part of the screen.
- The Hamar Laser backup is named FACTORY. Follow the screen instructions to restore the PDA to the factory installation level.
Method 2 – Restoring the Read9 Software from the SD Card
Note: Use Method 2 if your PDA does not have a Data Backup utility or if you cannot locate the ACTORY backup
F
- Close all programs.
- Click Programs from the top-level menu.
- Click the File Explorer icon to open the browser.
- Click My Devices located on the upper left of the screen, and scroll down to SD Card.
- Install the listed software in the following sequence:
(STEP 1) elSer…
(STEP 2) msv…
(STEP 3) Read…
- Reboot the PDA by pressing the Reset Button located on the back of the unit.
Resetting the Dell Axim X51 Series Pocket PCs
A “soft” reset clears all open programs and “reboots” the Pocket PC. When the Pocket PC powers back up, you’ll start with all active programs closed and the device ready to use. This procedure is intended to reset the Pocket PC if it is malfunctioning or has become bogged down. This reset is also sometimes necessary after software is installed. A soft reset is the Pocket PC equivalent to restarting your Desktop or Laptop.
The Dell Axim X51 and X51v can be soft reset by pressing the recessed button on the rear of the unit above the battery.
A “hard” reset wipes the RAM and returns the Pocket PC to its factory specs. In effect, the Pocket PC will be just as it was when you purchased it. All data entered, preferences set or software installed (other than ROM updates) on the Pocket PC after purchase will be lost after a hard reset and will have to be transferred or reinstalled via ActiveSync / Windows Mobile Device Center.
The Dell Axim X51 Series Pocket PCs can be hard reset by performing the following procedure:
With the unit turned on, press and hold the power button at the top of the unit. While holding the down power button, use the stylus tip to press the “Reset” button mentioned above. Allow the screen to fade to off. Release both buttons. The unit will power back on and display a menu to confirm the hard reset request. The Axim will be hard reset, just as it was when it left the factory.
