If you have set the computer to suspend to the hard disk, you won’t be able to return to the active
system state without first completely suspending to disk and then restoring. In this case, you
should definitely connect the AC adapter before you reactivate the system. Restoring the active
system state is very disk-intensive and could use up the battery before the system fully restores.
A better approach is to keep your eye on the battery gauge, and recharge or place the battery
before time gets critical. If you don’t want to use this feature, leave it disabled.
Modem Ring Resume
When you enable this, the system will automatically ‘wake up’ (Resume) from Suspend-to-RAM
if the fax modem detects an incoming call on the telephone line connected to it. The default
setting for this is “Disabled”.
Alarm Resume
This works like an alarm clock. When enabled, the system will automatically ‘wake up’
(Resume) from Suspend-to-RAM at a time you set in the “Alarm Time” field that follows it. The
default setting for this is “Disabled”.
Alarm Time
This is where you set the alarm for the “Alarm Resume” feature. The time format is 24-hour or
“military” time. The alarm will activate and wake up the system at the next point the system
clock reaches the time you set. This will either be during the same day, or on the next day if the
time you set has already passed on the day you set the alarm.
For example, if at the end of the day you want to set your computer to wake up at 8 AM the next
morning, you would enable “Alarm Resume” and then set the Alarm Time to 08:00. As you can
see, you can also use this feature with the AC adapter connected.
To set the time, select either the hour or minute field and use the plus or minus keys to scroll to
the setting you want.
BE A CONSERVATIONIST
At your end, there are many things you can do to extend the usable period of one battery charge.
First of all, try to use AC power whenever possible. It may be tempting not to bother, but a little
extra effort will leave you with a full battery when you really need it. Otherwise, you should use
the power management software. Set it up to match your work habits and preferences. If your
habits and preferences don’t contribute to conserving power, you can consider adopting habits
that do.
For example, many people use a ‘screen saver’ nowadays. These are fine for a desktop computer
(where they are intended to prevent wear on the desktop monitor) or for when you are using the
AC adapter to power the computer, but a screen saver still requires that the LCD screen operate
at full power. A better solution for battery operation is to use the setting that turns the LCD off
when you don’t use the computer for more than two minutes – or whatever length of time you
set.
