Power Management Settings

Depending on your patterns of computer use, you can set different levels of

power management. These different power management levels can be

activated based on the amount of time passed since the last system activity.

System activity examples include keyboard or mouse movement, CD or DVD

playback (while under program control that monitors Sleep), and modem use.

You can select different conditions or power schemes through Power

Management.The optional settings are Home/Office Desk, Portable/

Laptop, and Always On. From the default settings, you can change the

following settings:

● the System goes to Sleep (Standby) mode

● the screen times out and goes blank

● the hard drive spins down

Each of these system components goes to sleep after the selected or default

periods of inactivity.

(The setting for hard drive must be less than, or equal to, the setting for

System.)

IMPORTANT:

If you're on a network, it's recommended that you set

System Standby to Never.

There are five categories of power management settings under the Control Panel.

The default settings for each feature are listed in the following tables:

Power Management for Windows 98

Sleep

You can select Sleep mode instead of turning off the computer when you have finished using it.

This allows the computer to wake up faster than turning it off and saves power over the active

(On) mode. Compaq Presario Notebook computers have two levels of sleep - Hibernation and

Sleep.

Hibernation - pushing the power button once causes your computer to perform a save to disk

followed by a

shut down of the computer into Off mode.

Sleep - is a low-power mode, also referred to as Standby mode. While in Sleep mode, your

computer maintains system information and open files. Unsaved information is lost if you turn off

your system before system wake-up, or if you lose power while using the AC adapter.

CAUTION: While in Sleep mode, your computer maintains system information and open

files. Unsaved information is lost if you turn off your system before system

wake-up, or if you lose power while using the AC adapter

Hibernation Mode

Hibernation helps conserve battery life and protect your data. Hibernation can

be a routine power saving event, or can be the result of a low battery

condition. As it enters Hibernation, your computer displays a progress screen,

as it automatically saves the machine state before it shuts down and turns

itself off. Your computer automatically goes into Hibernation when the

battery has little power left, or when the system (operating on battery power)

has been in Sleep mode for more than an hour. You can also manually initiate

Hibernation by pressing the power button once while the system is active. To

restore the computer's previous state, simply press the power button once

again. While waking up, the computer displays a progress screen.

The following table shows the conditions and indicators for getting in and out

of the various power management modes - Sleep, Hibernation, and Off.

Preliminary Steps

Before running POST, complete the following preliminary steps:

1. If a power-on password has been established, type the password and press the Enter key. If

the password is not known,

clear the password.

2. Run Computer Checkup.

3. Turn off the computer and its external devices.

4. Disconnect any external devices that you do not want to test. Do not disconnect the printer if

you want to test it or use it to log error messages.

IMPORTANT:

If the problem only occurs when an external device is connected

to the computer, the problem may be related to the external

device or its cable. Verify this by running POST with and without

the external device connected.

5. Install loopback plugs in the serial and parallel connectors if you would like to test these ports.

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

7. Ensure that the battery pack is inserted in the computer and the computer is connected to an

external

AC power source.

When these preliminary steps are completed, you are ready to run

POST.

Power-On Self Test (POST)

Running POST

To run POST, complete the following steps:

● Turn off the computer; then, turn on the computer.

● If POST does not detect any errors, the computer will not beep. This indicates successful

completion of POST test. POST has run successfully and boots from the hard drive (or from a

bootable diskette if one is installed in the diskette drive).

● If POST detects errors, the errors are indicated by screen and/or audible messages.

Refer to "Power-On Self-Test (POST) Codes" in the tables for a list of POST codes and their relevant

descriptions.

NOTE:

If the system is not functioning well enough to run POST, or if the display is

not functioning well enough to show POST error messages, refer to the

Troubleshooting tables.
