Power Management

The following power management features are available for conserving AC power and extending battery operating time:

• Power Management Settings

• Low-Power Modes

• Battery Operating Life

• Servicing the Notebook - Full Off Mode

• Rebooting After a Lockup

• Recovering From a Loss of Electrical Power

Power Management Settings

Different patterns of Notebook use determine the level of power management needed. These power management levels can be initiated based on the amount of time passed since the last system activity. System activity examples include keyboard strokes or mouse movement, DVD/CD playback (while under program control that monitors Standby), and modem use.

Power Schemes

You may select different settings or Power Schemes through Power Management from the Control Panel. The default Power Schemes are Home/Office Desk, Portable/Laptop, and Always On. The settings can be customized by changing the following options:

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

mode

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

• Turn Off Hard Disks: 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.

Low-Power Modes

Compaq Presario 1600XL Series Notebook Computers have two levels of low-power management: Hibernation and Standby.

Hibernation

Hibernation helps conserve battery life and protect data. The Notebook automatically enters Hibernation mode 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 it shuts down. When the Notebook comes out of Hibernation, it returns to its former state.

Activate Hibernation mode by pressing the Power button once.

To restart the Notebook, press the Power button once. When the Notebook enters or wakes from Hibernation mode, a Progress window is displayed on the screen.

Standby

Standby is a low-power mode, also referred to as Sleep mode. Selecting Standby mode instead of turning off the Notebook when finished has two advantages: 1. It enables the Notebook to wake up faster than if it had been turned off completely; 2. It saves more power than the active (On) mode.

Activate Sleep mode by pressing Fn+F4. Or click Start, select the Shut Down option, and click Standby.

CAUTION:

ÄÄ

Standby mode. However, 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.

The Notebook maintains system information and open files while in

Servicing the Notebook - Full Off Mode

The Notebook must be turned off completely when installing or replacing components in the system. Follow the instructions for putting the Notebook into Off mode properly, unplugging it from the outlet, and removing the battery (see Battery Pack Removal

Sequence).

Rebooting After a Lockup

To reboot the Notebook (from a cold start) when the keyboard is frozen or the screen is locked, press and hold down the Power button for at least four seconds; this causes a manual shutdown. Then, restart the Notebook with a single press of the Power button.

If the Notebook still does not recover, press the Power button and hold for four seconds to shut it down, then remove the battery or unplug the AC power for at least 30 seconds. Reinsert the battery or reconnect AC power and press the Power button once to reboot.

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 files and programs properly.

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

• Electrical power service is interrupted.

• The power cord is accidentally disconnected.

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 caused any errors on the hard disk. These errors may occur if the Microsoft Windows operating system is not able to close all files properly 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 that was not saved before the loss of power or shutdown may be lost.

If a power failure occurs, or 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.

Battery Operations

This section explains the following topics concerning battery pack operating time:

• Increasing Battery Pack Operating Time

• Conditioning a Battery Pack

• Disposing of a Used Battery Pack

Increasing Battery Pack Operating Time

Battery pack operating time varies depending on several factors. To avoid unnecessary replacement, consider the following when determining how long a charged battery pack should last:

• Power management settings

• Hardware configuration

• Software applications

• Installed options

• Display brightness

• Hard drive usage

• Changes in operating temperature

• Type and number of installed PC Cards

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

Battery pack operating time can be increased by as much as 50 percent by controlling the amount of energy required by the computer and the energy stored in the battery pack.

Minimizing the Energy Required

To minimize the energy required by the computer, follow these steps:

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

• Customize the timeout value to work more efficiently with the applications. The

amount 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 the 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. This supplies

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

Troubleshooting

This section provides troubleshooting information for Compaq Presario 1600XL Series Portable Notebook. The basic steps in troubleshooting include:

1. Preliminary Steps

2. The Power-On Self Test (POST)

3. The recommended actions described in the diagnostic tables in case you are unable to run POST, or if POST displays an error message.

When following the recommended actions in the Sections on Power-On Self Test (POST) and Diagnostic Error Codes

, perform the steps in the order listed above. Rerun POST after each recommended action until the problem is solved, and if no error message occurs. Once the problem is solved, do not continue with any recommended actions remaining.

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 exposed to electrostatic discharge (ESD) may not seem to be affected at all and work perfectly throughout a normal cycle. Although it may function normally for a while, it may be 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 the associated electrostatic voltage level.

Tools and Software Requirements

The following items are required to service the computer:

• Torx T-9 screwdriver

• 5mm nut drivers (for screw locks and standoffs)

• Small standard screwdriver

Screws

The screws used in the Notebook are not interchangeable. If an incorrect screw is used during the reassembly process, it can damage the unit. Compaq strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations.

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

Cables and Connectors

Cables must be handled with extreme care to avoid damage. Apply only the pressure required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases avoid bending, twisting, or tearing the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced. Most of the cables used throughout the unit are ribbon cables.

Cables

Use the following precautions when handling cables to avoid damage to the cable or computer:

• 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 a location where they cannot be caught or snagged by parts being

removed or replaced.

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