If the computer you are servicing has an unknown password,
follow these steps to clear the password. These steps also
clear CMOS:
1. Prepare the computer for disassembly (refer to Section 5.3,
“Preparing the Computer for Disassembly,” for more
information.) Remove the real-time clock (RTC) battery
(refer to Section 5.8, “RTC Battery,” for more information.)
2. Wait approximately 5 minutes.
3. Replace the RTC battery and reassemble the computer.
4. Connect AC power to the computer. Do not reinsert any
batteries at this time.
5. Turn on the computer.

Product Description
1.5 Design Overview
This section presents a design overview of key parts and features
of the computer. 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:
■Mobile AMD Sempron and AMD Turion 64 processors
■Audio
■Digital media card
■Display
■ExpressCard
■Hard drive
■Keyboard
■Memory module
■Mini PCI communications devices
■PC Card
■TouchPad
ÄCAUTION: To properly ventilate the computer, allow at least a 7.6-cm
(3-inch) clearance on the left and right sides of the computer.
The computer uses an electric fan for ventilation. The fan is
controlled by a temperature sensor and is designed to turn 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. Exhaust air is
displaced through the ventilation grill located on the left side of
the computer.
