Introduction Do you know when the first laptops were developed?

Who do you think used the early laptops?

One of the original laptops was the GRiD Compass 1101. It was used by astronauts on space missions in the early 1980s.

It weighed 11 lb (5 kg) and cost US $8,000 - $10,000!

This chapter focuses on the differences between laptops and desktops and describes the features of PDAs and Smartphones.


Laptops and Portable Devices Notebooks, laptops, and tablets are types of portable

computers.

For clarity and consistency in this course, all portable computers will be called "laptops".

Today, laptops are very popular because advances in technology have resulted in laptops that cost less, weigh less, and have improved capabilities.

PDAs offer features such as games, web surfing, e-mail, instant messaging, and many other features offered by PCs.

Smartphones are cell phones with many built-in PDA capabilities.


Common Uses of Laptops Taking notes in school or researching

papers

Presenting information in business meetings

Accessing data away from home or the office

Playing games while traveling

Watching movies while traveling

Accessing the Internet in a public place

Sending and receiving email in a public place

Can you think of other uses for laptops?


Common Uses of PDAs and Smartphones The PDA is an electronic personal

organizer with tools to help organize information

The Smartphone is a mobile phone with PDA capabilities.

Other uses of PDAs and Smartphones are to take phone calls, voice memos, taking notes, text messaging, browsing the internet, reading eBooks, playing games, internet chat, music, contacts, calendar and GPS.


The Components of a LaptopCommon laptop features:

Small and portable

Integrated display screen in lid

Integrated keyboard

AC power source or rechargeable battery

Compare Laptop Components and Desktop Components Desktop components tend to be standardized. They

usually meet universal form factors.

Laptop manufacturers focus on refining laptop components to make them more efficient and compact as a result, laptop components are proprietary.

You may not be able to use components made by one laptop manufacturer to repair a laptop made by another manufacturer.

Configure Laptops To allow applications and processes to run smoothly:

Configure and allocate system resources

Install additional components and plug-ins

Change environmental settings to match software requirements.

A laptop can be customized for specific purposes by adding external components.

Adding external components is usually accomplished through the use of Plug and Play, but occasionally driver installation and additional configuration may be required.

Follow safe removal procedures when disconnecting hot-swappable and non-hot-swappable devices.


Configure Laptop Power Settings

ACPI Standards

S0 The computer is on and the CPU is running.

S1 The CPU is not running. However, the CPU and RAM are still receiving power.

S2 The CPU is off, but the RAM is refreshed. The system is in a lower power mode than S1.

S3The CPU is off, and the RAM is set to a slow refresh rate. This mode is often called “Save to RAM”. In Windows XP, this state is known as the Standby mode.

S4The CPU and RAM are off. The contents of RAM have been saved to a temporary file on the hard disk. This mode is also called “Saved to Disk”. In Windows XP, this state is known as the Hibernate mode.

S5 The computer is off and nothing has been saved.


Checking the ACPI Settings in the BIOSHere are the steps to check the ACPI settings in the

BIOS:

1. Enter BIOS setup by pressing the appropriate key or key combination while the computer is booting. Typically this is the Delete key or the F2 key, but there are several other options.

2. Locate and enter the “Power Management settings” menu item.

3. Use the appropriate keys to enable ACPI mode.

4. Save and Exit BIOS setup.


Power Settings in Windows XPTo configure your power settings, click:

Start > Control Panel > Power Options


Replacing Laptop Components

CAUTION: Always disconnect power and remove the battery before installing or removing laptop components that are not hot-swappable.


Mobile Phone Standards

Humidity


Troubleshooting

Determine if a repair is cost-effective.

The cost of the repair should be compared to the replacement cost minus the salvage value.


Step 1 Gather data from the customer
