The introduction to chapter 6 is about the evolution of laptops. The first ever laptop was created in 1979, it was called the GRID compass 1101 andwas created by NASA, it weighed 5kg and cost £10,000.
Netbooks, laptops and tablets are all types of portable pc. Netbooks, laptops and tablets are popular because they have the same technology as desktops but are lighter, portable, have a intergrated keyboard and a mouse which is called a touch pad, and laptops have a battery. PDAs and smartphone are all types of hand held devices that can do the same features that a pc can do. PDAs have been around since the 70s. PDAs and Smartphones can surf the net, go on games, recive messages and E-mails, have a built in camera and you can watch T.V on it.

Although laptops and desktops have the same components, you can’t replace a laptops motherboard with a desktop motherboard because of the size. The componets on a Desktop are the more or less the same size for every desktop computer. Where laptops components are different for every laptops because the manufactor decided the shape of the components depending on the size of the laptop.
The size of a desktop motherboard is bigger than a laptop motherboard, as you can see in this image.
Laptops cpu are designed to use less power, which means that the the laptops cpu will create less heat. Because the laptop cpu will create less heat the cpu does not have a fan to keep it cool unlike a desktopwhich has a massive fan that takes up a lot of room.
There are many expansion devices that can fit on a desktop. These are a printer, scanner, camera, keyboard, mouse, extra memory, extra hard drive and speakers. Where as on a laptop you can add a printer, scanner, mouse if you are not happy with the touch pad, extra memory and a extra hard drive.To make a pc and its applications run even smoother you can install more components and change the laptops setting. You can do this through plug in and play.
After you have had a laptop for a long period of time you will need to replace some of the laptops functions like the Battery, Hard drive, Optical drive, memory and pc card. If you had a desktop you could just buy them off the internet and they will fit, but with a laptop you will have to buy the components from the manufacturer of the computer.
There are many hazzardous areas for a laptop, because they are portable and can be moved anywhere. Some of theses hazzardous areas are putting them by food and drink, leaving a in a hot enviroment, leaving a laptop in a cold enviroment and leaving a laptop on the edge on a table where it could fall. To kept your laptops safe you can work in a clear space, in a climate where it is best to fit the manufacturer standards and leave the computer when it is not in use in a sturdy place.
It doesn’t matter how careful you are your laptop it will eventually get dirty and will need to be cleaned. To clean a laptop you need to a soft lint-free cloth, tweezers, compressed air, cotton lint- free cloth and a cleaning solution.
The final part of chapter 6 is troubleshooting. Troubleshooting is a form of problem saving that is used to repair failed application. To troubleshoot you need to:
1. Gather infomation from the customer
2. Verify the obvious issues
3. Try quick solution first
4. Gather information from the computer
5. Evaluate the problem and implement the solution
6. Close with the customer
That was my summary of chapter 6
