Chapter 13: Critical Concepts
 What is this chapter about and why is it important?
 Laptops, notebooks, netbooks, nettops, and other small portable computers are
becoming commonplace in both the business and home environment. These
devices have all the same components as a desktop computer, but in a smaller
footprint, with lower capacities, less powerful processors, more use of wireless
communications, and their own set of issues. When dealing with these laptop
matters, the theory is the same as when dealing with desktop memory, hard drives,
processors, and other hardware. However, the implementation is different. In this
chapter, students are exposed to more information about wireless communication,
laptop repairs, and common laptop problems and solutions.

Chapter 13: Classroom Management
 Obtain old and broken laptops from advisory committee members, parents,
students, the school, administrators, and fellow instructors to use in the classroom.
Allow students to disassemble these old and broken laptops for part identification.
 Even if only one laptop is available, use it to demonstrate the laptop parts and the
troubleshooting procedure if possible.
 Use scenario-based discussions about laptop problems. Have students bring in a
laptop problem. The class could solve the laptop problems together using
collaborative techniques and the Internet. Use the graphics on 13.5.2 to lead your
discussions.

Chapter 13: Teaching Analogies
 Operating a laptop on battery power with all devices, including the wireless NIC, is
like turning on every electrical light and appliance in your house when the entire
residence is powered by a generator. You will run out of power quickly.

Chapter 13: Best Practices
 Laptops and battery life are a common source of issues for users. Have the
students bring in three suggestions for prolonging the operation time of the laptop
battery during a single session of laptop use.
 Research laptop problems on the Internet before class. Bring the problems to class,
have the students divide into teams, and give each team a problem. Tell one half of
the team the solution. Have the other half of the team ask questions in order to
arrive at a solution. For example, a laptop is running out of memory and
experiencing errors. One half of the team could ask, how many applications are
open when this occurs? The other side of the team answers based on what they
know.
 Search on the Internet for the following term to get help from sites for laptop repair:
laptop disassembly guide.
