3 Routine care, SATA drive guidelines, and

disassembly preparation

This chapter provides general service information for the computer. Adherence to the procedures and

precautions described in this chapter is essential for proper service.

CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system

board. You must disconnect the power cord from the power source before opening the computer to prevent

system board or component damage.

Electrostatic discharge information

A sudden discharge of static electricity from your nger 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 (ESD) may not appear to be aected at all and can work perfectly

throughout a normal cycle. The device may function normally for a while, but it has been 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.
