Product Description
Setting Standby
Standby is initiated by pressing the Fn+F4 hotkeys or automatically by the computer if it reaches the defined percentage of battery pack power remaining. When Standby is initiated, several subsystems will power off to conserve energy. The system will wake up from Standby when a key is pressed. Although the Standby mode maintains the information and opens the file upon wake-up, any unsaved information is lost if the computer is turned off before ending Standby.
Hibernation
Hibernation is an energy-saving feature and safeguard that saves information in RAM to a hibernation file on the hard drive, then shuts down the computer. Hibernation is initiated by the computer when the computer reaches the defined percentage of battery pack power remaining. To wake the computer from Hibernation, press the power button. When you resume work, the information returns to the screen where you left off. The computer uses the operating system with a power management utility that helps you maintain and conserve power when the computer is running on battery power.
Standby
Standby is an energy-saving feature that conserves power and reduces startup time. Standby reduces power to system components that are not being used. Standby can be initiated by you or by the system. When Standby is initiated, all work is saved in random access memory (RAM) and the screen is cleared. When work is resumed, the information returns to the screen. Refer to Section 1.4 in this chapter to identify the Power, Standby, and Hibernation controls.

These conditions are affected by high external temperatures, system power consumption, power management/battery conservation configurations, battery fast charging, and software applications. Exhaust air is displaced through the ventilation grill located on the right side of the computer.
Ä
CAUTION: To properly ventilate the computer, allow at least a 3-inch (7.6 cm) clearance on the left and right sides of the computer.

Removal and Replacement Preliminaries
This chapter provides essential information for proper and safe removal and replacement service.
4.1 Tools Required
You will need the following tools to complete the removal and replacement procedures:
I I I
Magnetic screwdriver Phillips P0 screwdriver Tool kit (includes connector removal tool, loopback plugs, and case utility tool)
4.2 Service Considerations
Listed below are some of the considerations that you should keep in mind during disassembly and assembly procedures. computer, place As you remove each subassembly from thethe work area to it (and all accompanying screws) away from prevent damage.
Maintenance and Service Guide
41
Removal and Replacement Preliminaries
Plastic Parts
Using excessive force during disassembly and reassembly can damage plastic parts. Use care when handling the plastic parts. Apply pressure only at the points designated in the maintenance instructions.
Cables and Connectors
Cables must be handled with extreme care to avoid damage. Apply only the tension required to unseat or seat the cables during removal and insertion. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing cables. Ensure that 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 tear easily.
Ä
CAUTION: When servicing the computer, ensure that cables are placed in their proper location during the reassembly process. Improper cable placement can damage the computer.
4.3 Preventing Damage to Removable Drives
Removable drives are fragile components that must be handled with care. To prevent damage to the computer, damage to a removable drive, or loss of information, observe these precautions:
I
Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, then shut it down. Before removing a diskette drive or optical drive, ensure that a diskette or disc is not in the drive. Ensure that the optical drive tray is closed.
I
42
Maintenance and Service Guide
Removal and Replacement Preliminaries
I
Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector. Handle drives on surfaces that have at least one inch of shock-proof foam. Avoid dropping drives from any height onto any surface. After removing a hard drive, CD-ROM drive, or a diskette drive, place it into a static-proof bag. Avoid exposing a hard drive to products that have magnetic fields such as monitors or speakers. Avoid exposing a drive to temperature extremes or to liquids. If a drive must be mailed, do the following: place the drive into a bubble pack mailer or other suitable form of protective packaging; label the package "Fragile: Handle With Care."

Removal and Replacement Preliminaries
4.4 Preventing Electrostatic Damage
Many electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. 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. 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 may not be affected at all and can work perfectly throughout a normal cycle. It may function normally for a while, then degrade in the internal layers, reducing its life expectancy.
4.5 Packaging and Transporting Precautions
Use the following grounding precautions when packaging and transporting equipment:
I I I I I
To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes. Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging. Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations. Place items on a grounded surface before removing them from their container. Always be properly grounded when touching a sensitive component or assembly.
44
Maintenance and Service Guide
Removal and Replacement Preliminaries
I I
Place reusable electrostatic-sensitive parts from assemblies in protective packaging or non-conductive foam. Use transporters and conveyers made of antistatic belts and roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground, and that proper materials were selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
4.6 Workstation Precautions
Use the following grounding precautions at workstations:

Cover the workstation with approved static-dissipative material (refer to Table 4-2). Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment. Use conductive field service tools, such as cutters, screwdrivers, and vacuums. When using fixtures that must directly contact dissipative surfaces, use fixtures made of static-safe materials only. Keep the work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam. Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM laminate. Handle them only at static-free workstations. Avoid contact with pins, leads, or circuitry. Turn off power and input signals before inserting or removing connectors or test equipment.

4.7 Grounding Equipment and Methods
Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.
I
When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap snug against the skin at all times. On grounded mats with banana-plug connectors, connect a wrist strap with alligator clips. When standing, use foot straps and a grounded floor mat. Foot straps (heel, toe, or boot straps) can be used at standing workstations and are compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use them on both feet with a minimum of one-megohm resistance between the operator and ground. To be effective, the conductive strips must be worn in contact with the skin. Other grounding equipment recommended for use in preventing electrostatic damage includes:
