SPARCbook Portable Workstation User Guide
Your SPARCbook can be moved while in the Sleep mode and operates
for typically 5 hours from a fully charged internal battery. If the battery
nears discharge while it is in the Sleep mode, your SPARCbook
performs a Save on low battery as described in the previous section.
Save and Resume and Security
The Save and Resume feature makes your SPARCbook vulnerable to
unauthorized use. This is because Resume will take the system back
into your last desktop session, effectively bypassing the normal login
prompts.
One way to protect your SPARCbook against unauthorized use is to
remove the hard disk while it is without power. Refit it again when you
next wish to use your SPARCbook, before you power on.
If this level of protection is not sufficient, you have the following
options:
•
Power off using a conventional Solaris system shutdown. To do
this, log in as root and enter the
init 0
command.
This takes the system down to the OpenBoot prompt and a safe
state for power-off. Power off by pressing
Pause-O
. The next
time you power on your SPARCbook carries out a full system
startup and not a Resume. See “Using Full System Startup” on
•
Disable Save and Resume altogether, see below.
