Powering Off the System
Powering On the System
Before you begin any removal or replacement procedure, you must halt the
system in an orderly manner. The procedure to use depends upon whether
your system is working normally or not, as described in the next sections.
Caution – When the operating system or any other standalone program has
already booted, do not use the Stop-a keys to halt the system. Using the
Stop-a keys to abort program execution can damage data files.
To halt your system when it is working normally:
1. Save all your work.
Consult your software documentation for instructions on ending a work
session and saving your files. If you do not save your work, you could lose
it when you switch off the power.
