roubleshooting Procedures
This section provides troubleshooting procedures for
components inside your computer (such as a memory
module) and for external devices that connect to your
computer (such as an external monitor). Before perform-
ing any of the procedures in this section, see "Basic
Checks" found at the beginning of this chapter and read the
safety instructions at the front of this guide. Then perform the
appropriate troubleshooting procedure for the component or
equipment that is malfunctioning.
NOTE: When you see the question "Is the problem
resolved?" in a troubleshooting procedure, perform the opera-
tion that caused the problem to see if the problem still occurs.
Many of the following procedures refer to the power,
drive access, and battery indicators (Figure 3.5)
