Clean Booting the Computer
If the computer does not warm boot or cold boot, you may need to
perform a clean boot. When you clean boot the computer, the
computer only loads files and applications that are absolutely
required by the operating system. A clean boot returns the computer
to an “out of the box” or factory default state, so that you can run
diagnostic tests to troubleshoot the normal boot process.
To clean boot the computer
1 Remove the battery pack.
2 Install the battery pack and press
^.
3 When the computer starts the boot process, simultaneously press
< and
> until the IPL Boot Configuration Menu appears on the
screen.
4 Press
2 to select Force Clean Boot and then press 0 to select
Continue with Boot.
The computer executes the clean boot. This process takes a few
minutes.
5 When prompted, tap the screen to set up the computer.
6 Follow the instructions to calibrate the screen.
The clean boot process erases the mobile computer memory,
including all applications and data files in the object store. To
preserve applications through a clean boot, store them in the
Flash File Store. For more information, see “How to Install
Applications on the CS40” on page37.
