These tools are discussed in more detail in the following sections.
Hand Tools
When you work with PC systems, the tools required for nearly all service operations
are simple and inexpensive. You can carry most of the required tools in a small pouch.
Even a top-of-the-line “master mechanics” set fits inside a briefcase-sized container. The
cost of these toolkits ranges from about $20 for a small service kit to $500 for one
of the briefcase-sized deluxe kits. Compare these costs with what might be necessary
for an automotive technician. An automotive service technician would have to spend
$5,000-$10,000 or more for a complete set of tools. Not only are PC tools much less ex-
pensive, but I can tell you from experience that you don't get nearly as dirty working on
computers as you do working on cars.
In this section, you learn about the tools required to assemble a kit that is capable of per-
forming basic, board-level service on PC systems. One of the best ways to start such a set
of tools is to purchase a small kit sold especially for servicing PCs.

the following sources:

For tools only, I also recommend Stanley Supply & Services (formerly Jensen Tools and
Contact East [

Most of these companies also have comprehensive paper catalogs, which can often make it
easier to do general browsing and find what you need.
Because they work better than conventional screwdrivers, use nut drivers to remove the
hexagonal-headed screws that secure the system-unit covers, adapter boards, disk drives,
and power supplies in most systems. You will, however, still need standard screwdrivers
for systems that have substituted Phillips-head screws for the more standard hexagonal-
head screws. If slotted screws are used, they should be removed and replaced with Torx
