Electrostatic discharge damage. 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, ESD contains enough power to alter HP laptop parameters or melt silicon junctions. A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. Even if the spark is neither felt nor heard, damage may have occurred.
An electronic device exposed to ESD may not be affected at all and can work perfectly throughout a normal cycle. Or the device may function normally for a while, then degrade in the internal layers, reducing its life expectancy. Before removing the display assembly, follow these steps:
1. Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, and then shut it down through the operating system.
2. Disconnect all external devices connected to the computer.
3. Disconnect the power from the computer by first unplugging the power cord from the AC outlet and then unplugging the AC adapter from the computer.
4. Remove the battery (see Battery on page 50).
5. Remove the following components:
a. Switch cover and keyboard (see Switch cover and keyboard on page 61)
b. Speakers (see Speakers on page 66)

When installing: Before you attach the fan assembly to the computer, apply thermal grease, at an amount of 0.2 grams, on the part marked a as in the following figure. Either too much or too less application of grease can cause a thermal problem due to imperfect contact with a component. In some modes, you need to peel the thin
film off from the rubber
