Cold Booting the CN50
In some cases where the computer completely stops responding, it
may be necessary to perform a cold boot. Because cold booting may
result in data loss, only use this method if all other recovery methods
have failed.
To cold boot your CN50
1 Remove the battery pack from the CN50.
2 Reinsert the battery pack and press £.
Clean Booting the CN50
If the CN50 does not warm boot or cold boot, you may need to
perform a clean boot. When you clean boot the CN50, the CN50 only
loads files and applications that are absolutely required by the
operating system. Perform a clean boot to get the CN50 up and
running so that you can run diagnostic tests to troubleshoot the
normal boot process.
To clean boot the CN50
1 Remove the battery pack, reinsert it, and press £.
2 When the CN50 starts the boot process, simultaneously press <
and > until the IPL Boot Configuration Menu appears on the
screen.
3 Press 2 to select Force Cold Boot and then press 0 to select
Continue with Boot.
The CN50 executes the clean boot. This process takes a few
minutes.
Note: Cold booting the CN50 does not guarantee that cached disk
data will be saved, so transactional data may be lost during the reset.
All other data is preserved.
The clean boot process erases the CN50 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 “Installing Applications on the
Computer” on page 42.
