Stuck during the boot or resume process
26 Jun 2008
On rare occasions, one of our rugged handheld computer products may get stuck during the boot or resume process. This leaves the product in an unusable state showing only a screen similar to as described in this list.
- Orange screen with progress bar or dotted circle
- Blue or green "Ultra-Rugged Field PC" screen (with or without progress bar)
- Green "Windows Mobile" logo screen
- Fully white, gray, or black screen
- System password screen
- Blank screen (sometimes with no indications of power supply)
Make sure you do not have an incompatible SDXC card inserted (since only SD and SDHC cards are supported). Though most often such issues are caused by a corruption in the Windows registry or operating system file(s). On rare occasions it can instead be caused by a hardware component that will not respond. Some possible solutions are described in order of recommendation below.
Perform a software reset by pressing and holding the Power (On/Off) button for a full 5-7 seconds. Release the button and wait several seconds for any indication of change in condition.
Perform a hardware reset by pressing and holding the Power (On/Off) button for a full 15-20 seconds. Release the button and wait several seconds for any indication of change in condition.
Remove all power supplies including battery pack(s) for a full 20 minutes (which is necessary to drain the backup super capacitor which normally is intended to maintain suspend mode power while swapping battery packs). The process may be accelerated by pressing and holding buttons, though this not recommended and no progress indications are given.
Setting only the Windows registry to a factory default state is only recommended for potential data recovery or if first performing a full Clean Boot (as explained below) does not respond. This process may leave the user interface in an unusable condition, requiring a full Clean Boot to then be performed or the operating system to be reloaded / updated. Follow the instructions given in the user guide (manual) or in the Clean Windows Registry article. Contact us if you can not find this procedure and feel you need it.
Return all accessible internal memory to a factory default state by perform a full Clean Boot as explained in the user guide (manual) or at the following links.
- Archer Set to Factory Defaults (Clean Boot)
- Allegro or TK6000 Clean Boot (restore system to factory defaults)
- Mesa Clean Boot (Set Factory Defaults)
Reload or Update Operating System
You may be able to reload the operating system by downloading and following the operating system update process. Operating system files and instructions are available in our Downloads section. This is particularly important for Archers that have still been running the Microsoft Windows Mobile 5.0 OS release 2.1.3 build which should be updated to the 2.1.5 build as explained in the Release Notes document.
If the handheld will not connect to ActiveSync/WMDC for running the "Desktop Install EXE" OS update utility, most of our products can alternatively install the OS directly from an inserted SD card. For the "Direct Install ZIP" file from which to extract the SD files, see the bottom section of the full OS download article for your product.
Re-Install or Correct Application Software
Application software can often cause Windows registry corruptions and possible operating system file issues. Make sure you have the latest app software version installed. Or you can contact and work directly with the app software developer to make an improved version to prevent such issues from occurring in the future, such as by applying the suggestions at the following web pages.
- Program memory (RAM) limitations and management
- Running slow or locking up
- Data or job file corrupted or causing lock ups
Submit Order to a Repair Center
If the unit continues to have issues while booting or resuming, then it may need to be returned to a Repair Center for evaluation.
