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 sleepHibernation 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.
http://h18000.www1.hp.com/athome/support/msgs/1245/power3.html [12/9/2002 9:08:31 AM]

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 modesSleep, Hibernation, and Off.

Service Considerations

Listed below are some of the considerations that you should keep in mind during the disassembly and re-assembly of the computer.
Tool and Software Requirements
To service the computer, you need the following:
Compaq screwdriver kit (Spare Part No. 161946-001) Torx T-9 screwdriver 3/16-inch and 5mm nut drivers (for screwlocks and standoffs) Small, standard screwdriver Small, Phillips screwdriver Diagnostics software

Screws

The screws used in the computer are not interchangeable. If an incorrect screw is used during the reassembly process it can damage the unit. Compaq strongly recommends that each screw removed during disassembly be kept with the part from which it was removed, then returned to the original location. As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage.
http://h18000.www1.hp.com/athome/support/msgs/1245/service.html [12/9/2002 9:11:19 AM]

Cables and Connectors

Most cables used throughout the units are ribbon cables; they must be handled with extreme care to avoid damage. Use the following precautions when handling cables to prevent damage to the cable or computer:
Apply only the required tension to seat or unseat the cables during insertion and 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. Handle flex cables with extreme care; they can tear easily.
CAUTION: When servicing these computers, ensure that cables are placed in their proper location during the reassembly process. Improper cable placement can cause severe damage to the unit.
Select the desired illustration.

Plastic Parts

Plastic parts can be damaged if excessive force is used during disassembly and reassembly. When handling the plastic parts, use care. Apply pressure only at the points designated in the maintenance instructions.

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 computer 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.
Return to the top of this page.
Conditioning a Battery Pack
CAUTION: To avoid a loss of data, ensure that all data is saved before discharging a battery pack. To condition a battery pack, complete the following steps: 1. Plug in the AC adapter and allow the battery to charge until the LED light on the display stops blinking. Your battery gauge may read 100 percent for a period of time before LED light on the display stops blinking. Do not unplug the AC adapter until the arrow disappears. 2. Unplug the AC adapter and allow the battery to drain until the computer reaches hibernation and turns itself off. Do not plug in the AC adapter during this process or you will need to restart with Step No. 1. You may use the computer while the battery is draining. 3. Your battery is re-conditioned. 4. Plug in the AC adapter and begin using the computer. The table below shows the approximate battery pack charge times. Approximate Battery Charge Time Computer NiMH Battery Pack On Line 4.0 hours Off Line 2:00 hrs
Disposing of a Used Battery Pack
In the interest of safeguarding our environment, Compaq Computer Corporation recommends that nickel metal hydride (NiMH) battery packs be recycled. Battery packs should be handled in accordance with country, state, province, or local regulations. CAUTION: Never attempt to open or service a battery pack. Opening a battery pack not only damages the pack and makes it unusable, but also exposes potentially harmful battery components.

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).

CAUTION: To avoid a loss of data, ensure that all data is saved before discharging a battery pack.
To condition a battery pack, complete the following steps: 1. Plug in the AC adapter and allow the battery to charge until the Battery Charge Light on the front bezel of the Notebook goes out. Do not unplug the AC adapter until the charging light is off. 2. Unplug the AC adapter and allow the battery to drain until the computer enters Hibernation mode and turns itself off.
Note: You may use the Notebook while the battery is draining.
CAUTION: Do not plug in the AC adapter during this process. If the AC adapter is plugged in while the battery is draining, begin again with step 1 of the conditioning process.
3. The battery is reconditioned. 4. Resume normal use of the Notebook with AC power.
