Chapter Five - Power Management

A Suspend 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 following example demonstrates this function.
If the Hard Disk Time-out is set to 2 minutes, the Standby Time-out is set to 8
minutes, and Auto Suspend Time-out is set to 10 minutes, the following power
management events take place:
1. After two minutes of system inactivity the hard disk spins down.
2. After six additional minutes (a total of eight minutes of inactivity) the system
enters Standby.
3. After 10 additional minutes in the system Standby mode, the system suspends
to memory or disk.
After the system has suspended, operation can be resumed at the point in your
application where it was suspended.
The amount of time that the system remains suspended depends on the amount
of battery power remaining. Due to this limitation, you should always save your
data before the system suspends.
Hard Drive Spin Down
The hard drive is always spinning when in use; also if left idle with the system in
Full On mode. When the system is left idle for a set amount of time the drive will
power down or stop spinning. This is a power savings feature set in BIOS as a
default.
Batteries
Your computer comes with a rechargeable battery pack so you can operate the
computer without an external power source. When the battery pack is fully
charged, you can operate the computer for approximately three to four hours
under the following conditions:
•
The battery pack initially has a full charge.
•
No peripheral devices are installed.
•
The disk/CD-ROM drives run no more than 10 percent of the time.
