Running the computer on battery power

Running the computer on battery power

To ensure that the battery pack maintains its maximum capacity, operate the computer on battery power at least once a month until the battery pack is fully discharged. Refer to

“Maximizing battery life” on page 132 for procedures. If the

computer is continuously operated on AC power, either through an AC adapter or a docking station for an extended period, more than a month, the battery may fail to retain a charge. It may not function efficiently over the expected life of the battery and the Battery LED may not indicate a lowbattery condition.

For more information on running your system on battery power, consult

“Running the computer on battery power” on page 123

.

Powering down the computer

When you power down the computer, you have three options to choose from:

Shut down, which powers off the computer

Hibernation, which saves the current operating mode to the hard disk and powers off the computer

Standby, which saves the current operating mode to memory and enters a low power mode

Each option has its advantages.

TECHNICAL NOTE: Before using any of these options to power down your computer, save your files and make sure the disk activity lights are off.

If you change your mind and decide to continue working after all, wait a few seconds before turning the computer on again.

Shut down command

The Shut down command powers off the computer. When you start up again, the computer runs a self-test and loads the operating system. You must open any programs and files you want to use.

Factors to consider when choosing Shut down:

No power is used while the computer is shut down. This is the most efficient mode if you will be away from your computer for an extended time.

Restarting from Shut down uses the most time and battery power.

When starting up again, the system does not automatically open the programs and files you were previously using.

Hibernation command

The Hibernation command powers off the computer, but it first saves the current mode of the computer to the hard disk.

Since Hibernation does not require power to maintain the saved information, the system settings are retained indefinitely. Restoring information from the hard disk takes longer than restoring it from memory. When you start up again, the computer runs a self-test, loads the operating system, and then returns to the mode in which you left it.

Factors to consider when choosing Hibernation:

While in Hibernation mode, the computer uses no battery power.

Because the state of the system is held on the hard disk, no data is lost if the battery discharges while the computer is in Hibernation mode.

When starting up again, this choice uses less time and battery power than the Shut down option. But it uses a little more time and battery power to start up than the

Powering down the computer

Standby option, because information is being retrieved from the hard disk instead of from memory.

On restarting, the computer returns to the mode in which you left it, and opens all the programs and files you were using.

Standby command

The Standby command puts the computer into a powersaving mode. Standby stores the current state of the computer in memory so that, when you restart the computer, you can continue working from where you left off.

Factors to consider when choosing Standby:

While in Standby mode, the computer uses some battery power.

When starting up again, this choice uses less time and battery power than does Shut down or Hibernation.

On restarting, the computer returns to the mode in which you left it, and opens all the programs and files you were using.

NOTE

If you power down using the Standby command and the battery discharges fully, your information will be lost. Be sure to save your work often.
