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
Differing patterns of Notebook use determine the level of power management needed.
These power management levels can be initiated based on the amount of time since the
last system activity. System activity includes keyboard strokes, 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 System Standby. If the Notebook is on a network, Compaq recommends that
System Standby be set to Never.

Low-Power Modes
Compaq Presario 1200 Series Notebook Computers have two levels of low-power
management: Hibernation and Standby (also known as Sleep mode).
Hibernation
Hibernation helps conserve battery life and protect data. Your 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 the Notebook 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 has two advantages: It allows the Notebook to wake up
faster than turning it completely off; and it saves more power than the active (On) mode.
To activate Standby/Sleep mode, complete one of the following:
• Press Fn+F4.
• Click Start, select the Shut Down option, and click Standby.
CAUTION:

Servicing the Notebook - Full Off Mode
The Notebook must be turned off completely (Off mode) when installing or replacing
components in the system. Follow the instructions for properly putting the Notebook into
Off mode, 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 your 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, ScanDisk, a Microsoft Windows
utility program, runs automatically once power is restored. ScanDisk determines if 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 covers the following information concerning battery pack operating time:
• Increasing Battery Pack Operating Life
• Conditioning a Battery Pack
• Disposing of a Used Battery Pack
Increasing Battery Pack Operating Life
Battery pack operating life depends on several variables. To avoid unnecessary
replacement, consider the following variables 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 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 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.

Troubleshooting
This section covers troubleshooting information for Compaq Presario 1200 Series Portable
Notebook Computers. 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.
Note: If the problem is intermittent, check your computer several times to verify that
the problem is solved.
Preliminary Steps
Before running Power-On Self Test (POST), complete the following steps:
1. If a Power-on password is established, type the password and press the Enter key. If
you do not know the password, clear the password (See Clearing the Power-On
Password).
2. Run Compaq Diagnostics
.
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 notebook.

Electrostatic Discharge
A sudden discharge of static electricity from a finger or other conductor can destroy staticsensitive 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 works 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.
Typical Electrostatic Voltages

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