General Procedures
After you assemble a toolkit with the hand tools and utilities described in the preceding sections, you have everything you need to upgrade or repair a PC, except for the new components. Before you get started, take a few minutes to read through the following sections, which describe the common procedures and general knowledge you need to work on PCs. These sections describe the general tasks you perform almost anytime you work on a computer—things such as opening the case, setting jumpers and switches, manipulating cables, and adding or removing expansion cards. Instructions for specific tasks such as replacing a motherboard, disk drive, or power supply are given in the relevant chapters.
