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 inthe early 1980s.

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

This chapter focuses on the differences between laptopsand desktops and describes the features of PDAs andSmartphones.

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

computers.

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

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

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

Smartphones are cell phones with many built-in PDAcapabilities.



Common Uses of Laptops Taking notes in school or researching

papers

Presenting information in businessmeetings

Accessing data away from home or theoffice

Playing games while traveling

Watching movies while traveling

Accessing the Internet in a public place

Sending and receiving email in a publicplace

Can you think of other uses for laptops?



Common Uses of PDAs and Smartphones

The PDA is an electronic personalorganizer with tools to help organizeinformation

The Smartphone is a mobile phone withPDA capabilities.

Other uses of PDAs and Smartphones areto take phone calls, voice memos, taking

notes, text messaging, browsing theinternet, reading eBooks, playing games,internet chat, music, contacts, calendarand GPS.

Compare Laptop Components andDesktop Components

Desktop components tend to be standardized. Theyusually meet universal form factors.

Laptop manufacturers focus on refining laptop

components to make them more efficient and compactas a result, laptop components are proprietary.

You may not be able to use components made by onelaptop 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 byadding external components.

Adding external components is usually accomplishedthrough the use of Plug and Play, but occasionallydriver installation and additional configuration may berequired.

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

Configure Laptop Power Settings

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

S4

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

The computer is off and nothing has been saved.S5

The CPU is off, and the RAM is set to a slow refreshrate. This mode is often called Save to RAM. InWindows XP, this state is known as the Standbymode.

S3

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

The computer is on and the CPU is running.S0
