COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED Writer: KMosby Saved by: Jessica Gilbert Saved date: 08/11/98 4:04 PM Part Number: 316216-002 File name: ch04.doc
NOTE: The battery charge light is the right light on the front of the
computer. It turns on (solid) when a battery pack (in the battery bay or MultiBay) is charging. It turns off when fully charged. It blinks in a low-battery condition. When the battery charge light turns off, the battery packs are fully charged.

Using the Battery Gauge

Press the Fn+F8 hotkeys to show the status of the battery pack(s). Two numbered boxes indicate the status of each installed battery pack. s Battery pack 1primary battery in the computer battery bay. s Battery pack 2battery in the computer MultiBay.

Using Hibernation

Hibernation is a safeguard feature that saves your information when the computer reaches a low battery condition while it is left unattended. When your computer hibernates, all the information in system memory is saved to the hard disk and the power to the computer is turned off. When you turn on the computer, your information returns to the screen at the point where Hibernation initiated. Hibernation behaves like a bookmark, and none of your information is lost. When Hibernation is initiated, it creates a file on the hard drive at least equal in size to the amount of total random access memory (RAM). If there is not enough space on the hard disk to store the information, an insufficient disk space message is displayed. Hibernation will automatically initiate as long as it is not disabled (turned off) through the software. If you disable Hibernation and the computer reaches a low battery condition, your unsaved information will be lost. CAUTION: If a low battery condition occurs and you continue to
use the computer, the system may not hibernate and your unsaved information will be lost.

Enabling Hibernation

If you have disabled Hibernation, you can enable it again through the Hibernation tab in Power Properties (click Start Control Panel double-click Power Power Properties). When you enable Hibernation this way, the system uses a certain amount of hard disk space necessary for Hibernation to take place.

Initiating Hibernation

Hibernation can be initiated by you or by the system. When Hibernation occurs, the system: s clears the screen. s saves all current information in memory to the hard disk. s turns off the computer.
Computer Power and Power Management 5-7
In Windows 95, you can initiate Hibernation by pressing Fn + Suspend button at any time and from within any application. System-initiated Hibernation takes place under the following conditions: s when the computer is on and unattended, and a critical low battery condition occurs. s when the computer is in Suspend, and a critical low battery condition occurs.

Exiting Hibernation

To exit hibernation and resume work: 1. Install a fully charged battery pack or connect to an external power source. 2. Turn on the computer by sliding the power switch. The computer exits Hibernation. The information that was saved to the hard disk returns to the screen at the point where Hibernation was initiated.

In Windows 95, when the Medium, High, or Custom level of battery conservation is used. You can initiate Suspend at any time by:
pressing the Suspend button. clicking Suspend from the Windows Start menu.
When Suspend is initiated, the computer beeps twice, the screen blanks, and the power/suspend light blinks.

Exiting Suspend

To exit Suspend, press the suspend button. When the system exits Suspend: s the computer beeps twice. s the power/suspend light turns on. s your information returns to the screen.
IMPORTANT: The computer will not exit Suspend if battery power
is low or the battery is dead. You must find a new power source for your computer. When a new power source is connected to the computer, press the suspend button to return your information to the screen.
5-10 Computer Power and Power Management

Using Timeouts

Timeouts are specified periods of system or component inactivity. Timeouts work with battery conservation to conserve power. When a timeout period has expired, battery conservation shuts down the system or components in order to save power. For example, the hard disk idle default timeout is two minutes. Therefore, if an application does not access information on the hard disk in less than two minutes, the hard disk shuts down until it is accessed again. Timeout values are set using the Battery Conservation Settings or Hibernation tab in Power Properties (click Start Control Panel double-click Power Power Properties). Using these utilities, you can: s use the preset timeouts provided with the medium (default) or high level of battery conservation. or s set your own component timeouts in conjunction with the custom level of battery conservation so that the computer works more efficiently with your applications.
Setting Component Timeouts
If you are running Windows 95, you can set your own timeout values for individual components of the computer. To set component timeouts: 1. Access the Power Properties utility by clicking Start Control Panel double-click Power Power Properties. 2. Click the Battery Conservation Settings tab. 3. Set the Battery Conservation level to Custom. 4. Using the drop-down boxes, select or type a timeout value for specific components of the computer, such as system idle and hard disk idle. 5. To save your settings, click OK when you are done. They become effective immediately and remain in effect until you change them.
