2-4 Resetting the MX2
MX2 Reference Guide Revision A MX2A137REFGD
Resetting the MX2
One of the critical features of any portable data-collection device is its
ability to protect against accidental data loss. In the event a MX2
becomes “locked up” or otherwise in a state in which data can no longer
be processed, you can use any of four methods to reset the unit. This
chapter describes these methods.
Warm Boot
The warm boot is one of two software methods for resetting a MX2. It is
analogous to the CTL-ALT-DEL key sequence for rebooting IBM-
compatible PCs, and the same key sequence is used to force a warm boot
on a MX2. This method of resetting a unit should be used first to attempt
to bring it back to a usable state.
Note: You do not need to press the FN key to activate the DEL
function of the BkSp key.
Since a warm boot can be attempted only from a unit that has been
turned on, certain assumptions are made. For example, the rigorous
hardware tests that are performed as part of the cold boot sequence are
not all necessary. This means the unit restarts faster with a warm boot
than with a cold boot.
During a warm boot, data written to the RAM drive (D), the flash drive
(C), or an ATA flash card will remain intact. However, if an application
is running on a unit before a warm boot, its state cannot be restored.
Note: If you do not want end users to be able to reset the unit, scan
the “Enable CTL-ALT-DEL Reboot Off” barcode in Appendix
C “Barcodes” to disable the CTL-ALT-DEL reboot.
Cold Boot
The second software method for resetting a MX2 is the cold boot. A
cold boot should be used only if a warm boot is unsuccessful.
Performing a cold boot is analogous to pressing the reset button on a PC
or to turning the PC’s power off and then back on.
To perform a cold boot on a MX2, first turn it off. Then press [ALT] +
[FN] + [Power], holding the first two keys down while pressing the
third.
