1.8 Design Overview

This section presents a design overview of key parts and features of the tablet PC. Refer to Chapter 3, “Illustrated Parts Catalog‚" to identify replacement parts, and Chapter 5, “Removal and
Replacement Procedures," for disassembly steps.
The system board provides the following device connections:
■ Memory module
■ Hard drive
■ Display
■ Optional keyboard and pointing stick
■ Audio
■ Intel Pentium-M or Celeron processor
■ Fan
■ PC Card
■ Secure Digital (SD) Memory card (not SDIO)
■ External MultiBay
■ Modem or modem/NIC
CAUTION: To properly ventilate the tablet PC, allow at least a 7.6-cm
Ä
(3-inch) clearance around the sides of the tablet PC.
The tablet PC uses an electric fan for ventilation. The fan is controlled by a temperature sensor and is designed to come on automatically when high temperature conditions exist. 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 left side of the tablet PC.

this equipment. All troubleshooting and repair procedures are detailed to allow only subassembly/module level repair. Because of the complexity of the individual boards and subassemblies, do not attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard. Any indication of component replacement or printed wiring board modification may void any warranty or exchange allowances.
