Power Saving Modes Chapter Five - Power Management
78
If you are conscious of power consumption, you will probably rarely operate the
computer with all power management features disabled.
Standby Mode
In addition to reducing the CPU speed, this mode puts peripheral components in
their lowest active states. These peripheral components include the hard disk, the
LCD screen and the screen backlight. The TREK 2 enters Standby mode when
the system remains idle for a specified amount of time. Press any key to resume
system operation.
Suspend Mode
In Suspend mode, the CPU power is turn off and most of the computer’s
peripheral components are put in their lowest active states. The computer enters
Suspend when the system remains idle for a specified amount of time. Press the
Power
button to resume system operation.
Suspend Mode Example
The time out settings for Hard Disk Off, System Standby, and System Suspend
specify the amount of time the system must be inactive before the next power
management level is enabled. The example below demonstrates this function. If
the Hard Disk Timeout is set to 2 minutes, the Standby Timeout to 8 minutes and
Auto Suspend Timeout is set to 10 minutes the following power management
events take place:
•
After two minutes of system inactivity the hard disk spins down.
•
After six additional minutes (a total of eight minutes of inactivity) the system
enters Standby.
•
After 10 additional minutes in the system Standby mode, the system
suspends to memory or disk.
After the system has suspended, operation can be returned (resumed) to the point
in your application where it was suspended.
Using the Suspend Mode
The system can be suspended in the following ways:
•
System enters Auto Suspend. This is enabled by setting a time out period
for the Auto Suspend field in the Power menu. This time out period is the
amount of idle time that the system allows before a Suspend is initiated.
•
System suspends to hard disk when battery level is critically low. A
PHDISK partition must be created on your hard drive to enable this feature.
•
Pressing and holding the power button for one second.
