The following power management features are available for conserving AC power and extending 

battery operating time:

●

●

     

●

     

●

     

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 will go 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.)

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 setting for each feature is 

listed below in the tables.

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 completely off and saves power over the active (On) mode. Compaq Presario Series 

Notebook computers have two levels of sleep, Hibernation and Sleep.

Hibernation - by pushing the power button once your computer will 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 will maintain system 

information and open files. Unsaved information will be lost if you turn off your system prior to system wake-up, or if you 

lose power while using the AC adapter.

CAUTION:  

While in Sleep mode, your computer will maintain system information and open 

files. Unsaved information will be lost if you turn off your system prior to system wake-up, 

or if you lose power while using the AC adapter.

 

Hibernation helps conserve battery life and protects 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 will display a progress screen, as it 

automatically saves the machine state before it shuts down and turns itself off. Your computer will automatically go 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 will display 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.

If you need to install or replace components in your system, you must turn the computer off completely. Follow the 

instructions above for properly putting the computer into Off mode, unplug from the outlet, and remove the battery (see 

battery section for 

).

Occasionally you may encounter a frozen keyboard or a locked screen. To reboot your computer (as if from a cold start) 

press and hold down the Power Button for at least four seconds, which will cause a manual shutdown. Then, restart it with 

a single press of the Power Button. If it still doesn't recover, press the Power Button and hold it 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.
