Battery and Power Management

This chapter describes power management and proper battery operating practices for Presario 1400 Series Notebooks. These practices include conservation of AC power and effective control of energy to extend the operating life of the battery. The following Power Mode sections also outline the correct methods of starting and shutting down the Notebook in various situations.

Power Modes

Presario 1400 Series Notebooks have three levels of low power: Hibernation, Standby, and Full Off.

Hibernation

Hibernation mode helps conserve battery life and protect data. The Notebook automatically enters Hibernation when the battery has little power left, or when the Notebook (operating on battery power) is in Standby mode for more than one hour. As the Notebook enters Hibernation, it automatically stores the contents of its memory to the hard drive before shutdown. When the Notebook wakes from Hibernation, it returns to its former state.

Note: When the Notebook enters or wakes from Hibernation mode, a Progress window is displayed.

To activate Hibernation mode, press the Power

To resume from Hibernation mode, press the Power

Ÿ button once.

Standby

Standby is a low-power mode, also referred to as Sleep mode. The Notebook maintains system information and open files while in Standby mode. Selecting Standby instead of turning off the Notebook when your have finished working has two advantages: 1. It allows the Notebook to wake up faster than it would if it had been turned off; 2. It saves more power than the Active-On mode.

CAUTION: Unsaved information is lost if the Notebook is turned off prior to system wake-up, or if a power loss occurs while using the AC adapter.

ÄÄ

To activate Standby/Sleep mode, press Fn+F4 or click Start. Select the Shut Down option, and then Standby.

To resume from Stand/Sleep mode, press any key.

Full Off

Full Off mode consumes no power. The battery charges continuously if the battery is installed while the Notebook is in Full Off mode and if the Notebook remains plugged into external AC power.

Note: Unsaved information is lost if the Notebook is turned off without first saving the data.

To activate Full Off mode, complete the following steps:

1. Click the Start button on the Windows taskbar.

2. Click Shut Down, then select Shut Down from the options.

To r es um e f r o m Full Off mode, press the Power button once.

CAUTION: The Notebook must be turned off (Full Off mode) when installing or replacing components. Follow the instructions for putting the Notebook into

ÄÄ

Full Off mode. Be sure to unplug the Notebook from the outlet, and remove the battery pack (refer to the removal procedures section: Battery Pack) before servicing any parts.

Power Settings

Power management modes can be initiated based on the amount of time passed since the last system activity. System activity includes keyboard strokes, mouse movement, CD/DVD playback, and modem usage.

Power Schemes

Different patterns of Notebook use determine the level of power management needed. The Power management settings can be selected using several predefined Power Schemes. To access these options, select Power Management on the Control Panel, then click the Power Schemes tab. The default Power Schemes are Home/Office Desk, Portable/Laptop, and Always On. Power Schemes can also be customized by changing the following options:

•

System Standby: the length of inactivity before the Notebook goes into Standby mode

•

Turn Off Monitor: the length of inactivity before the screen times out and goes blank

•

Turn Off Hard Disks: the length of inactivity before the hard drive goes into low-power mode

Important: The setting for the Hard Disk must be less than or equal to the setting for the System. If the Notebook is on a network, Compaq recommends that System Standby be set to Never.

Recovering From a Loss of Electrical Power

Loss of electrical power causes the Notebook to turn off automatically. This may cause loss of data because the Microsoft Windows operating system is not able to close all the files and programs properly.

Loss of power may be caused by one of the following:

•

Interruption of electrical power service

•

Accidental disconnection of the power cord

If power surges or sags, the display and status lights may flicker, and the Notebook may automatically restart. If an improper shutdown occurs, the Microsoft Windows utility program, ScanDisk, runs automatically once power is restored. ScanDisk determines whether the improper shutdown has caused any errors on the hard disk. These errors may occur if the Microsoft Windows operating system is not able to close all files correctly before the shutdown. If no errors are found, the restart process continues. If ScanDisk does detect errors, follow the instructions on the screen to continue the restart process. Work or information that was not saved before the loss of power or shutdown may be lost.

If a power failure occurs, or if the power cord disconnects while the Notebook is turned on, turn it off until normal service is restored. The next time the Notebook is turned on, ScanDisk may run to check the hard disk for errors caused by improper shutdown.

Increasing Battery Pack Operating Time

Battery pack operating life is affected by several variables. To avoid unnecessary replacement, consider the following when determining how long a charged battery pack should last:

•

Power conservation settings

•

Hardware configuration

•

Software applications

•

Installed options

•

Display brightness\\Server\projects\Compaq_Port\Portable TimesheetHard drive usage Changes in operating temperatures

•

Type and number of installed PC cards

Note: Power consumption requirements for PC cards vary widely. Some cards drain the battery pack very rapidly.

Battery pack operating life can be increased by as much as 50 percent by controlling the energy required by the Notebook and the energy stored in the battery pack.

Minimizing the Energy Required

To minimize the energy required by the Notebook, follow these guidelines:

•

Set the power conservation levels in the Power Management utility to Maximum.

•

Customize the time-out value to work more efficiently with the applications. The length of battery life depends on the values selected.

Maximizing the Energy Stored

To maximize the energy stored in the battery pack, follow these guidelines:

•

Condition a Battery Pack at least every 30 days to improve overall battery performance.

•

Keep a battery pack in the Notebook when using it with AC power to supply the battery pack with a constant trickle charge.

•

Store the battery pack in a cool, dry place when not in use.

Conditioning a Battery Pack

CAUTION: To avoid loss of data, make sure that all information is saved before completely discharging a battery pack.

ÄÄ

To condition a battery pack, complete the following steps:

1. Plug in the AC adapter and allow the battery to charge until the fast charge arrow on the status display disappears. The battery gauge may read 100% for a period of time before the arrow disappears.

Note: Do not unplug the AC adapter until the arrow disappears.

2. Unplug the AC adapter and allow the battery to drain until the Notebook enters Hibernation mode. The Notebook can be used normally during this process.

Note: If the AC adapter is connected while the battery is draining, the process must be repeated, beginning with Step 1.

The battery is now reconditioned. Plug in the AC adapter and begin using the Notebook.

Preliminary Steps

Before running the Power-On Self-Test (POST), complete the following steps:

1. If a Power-on password has been established, type the password and press the Enter key. If the password is unknown, clear the password (See Clearing the Power-On Password

2. Run the Computer Checkup (TEST)

3. Turn off the Notebook and all external devices.

4. Disconnect any external device that does not need testing. Do not disconnect the printer if it needs testing or if it is required to log error messages.

Important: If the problem only occurs when an external device is connected to the Notebook, the problem may be related to the external device or its cable. Check this by running POST both with and without the external device connected.

5. Install loopback plugs in the serial and parallel connectors if these ports need testing.

6. Ensure that the hard drive is installed in the Notebook.

7. Ensure that the battery pack is inserted into the Notebook, and that it is connected to an external AC power source.

When these preliminary steps are completed, run the Power-on Self-Test (POST)

Electrostatic Discharge

A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device that has been exposed to electrostatic discharge (ESD) may not seem to be affected and work perfectly throughout a normal cycle. Although the Notebook may function normally for a period of time, it may have been degraded in the internal layers, reducing the its life expectancy.

Networks built into many integrated circuits provide some protection, but in many cases the discharge contains enough power to alter device parameters or melt silicon junctions.

Generating Static

The table below shows activities that generate static electricity and the associated level of electrostatic voltage.

Service Considerations

During the disassembly and assembly of your Notebook, please keep in mind the considerations listed below.

Tool and Software Requirements

Customer serviceable parts only require the following items during disassembly:

•

Small standard screwdriver

•

Small Phillips screwdriver

•

Diagnostics software

Screws

The screws used on the customer removable parts are Phillips. These screws are not interchangeable. If an incorrect screw is applied during the reassembly process, it can damage the unit. Compaq strongly recommends that you keep all screws with their respective parts as they are removed during disassembly. Then replace the screws in their proper locations.

Important: As each subassembly is removed from the Notebook, place it away from the work area to prevent damage.

Note: Screws inside the Compaq Presario 1400 Series Portable Notebooks vary in size and are not interchangeable. During reassembly care must be taken to return the correct screws to their original location. Keep all screws with their respective subassembly during removal.

Electrostatic Discharge

A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device that has been exposed to electrostatic discharge (ESD) may not seem to be affected and work perfectly throughout a normal cycle. Although it may function normally for a period of time, it may have been degraded in the internal layers, reducing its life expectancy.

Networks built into many integrated circuits provide some protection, but in many cases the discharge contains enough power to alter device parameters or melt silicon junctions.

Generating Static

The table below shows activities that generate static electricity and their associated level of electrostatic voltage.

Typical Electrostatic Voltages

10% 40% 55%

Walking across carpet 35,000 V 15,000 V 7,500 V

Service Considerations

During the disassembly and assembly of the Notebook, please keep in mind the considerations listed below.

Tool and Software Requirements

To service the Notebook, the following items are required:

•

Torx T-8 or T-9 screwdriver

•

5mm nut drivers (for screwlocks and standoffs)

•

Small standard screwdriver

•

Small Phillips screwdriver

•

Cables and Connectors

Most of the cables inside the Notebook are ribbon cables. Handle cables with extreme care to avoid damage. During insertion or removal from the connector, apply only the amount of pressure required to seat or unseat the cable, handling it by the connector whenever possible. In all cases, avoid bending, twisting, or tearing the cables. Route cables in such a way that they cannot be caught or snagged by parts being removed or replaced.

Cables

To avoid damage to the cable or the Notebook, the following precautions should be taken when handling cables:

•

Always handle cables by their connectors.

•

Avoid bending, twisting, or pulling on the cables.

•

Apply minimum required force when seating or unseating the cables from their connectors.

•

Place the cables in such a manner that they cannot be caught or snagged by parts being removed or replaced.

•

Handle flex cables with extreme care; they can tear easily.
