Chapter 6. Troubleshooting This chapter describes diagnostic tools that are available to you. You can use these tools to identify and correct problems that might come up as you use your computer. Note If your computer does not start when you press the power switch, do the following: Make sure your computer and monitor are connected to working electrical outlets. Make sure all cables are securely connected to the correct locations. If this does not correct the problem, have the computer serviced. Computer problems can be caused by hardware, software, or user error (for example, pressing the wrong key). Using the diagnostic aids discussed in this chapter, you might be able to solve such problems yourself or gather helpful information you can pass on to a service technician. You can check the hardware by following the procedures in this chapter. You can also use the diagnostic programs provided with your computer (see "IBM Enhanced Diagnostics" on page 109 for a description of these programs). If the hardware checks out and you have not made a user error, you might have a software problem. If you suspect that you have a software problem, see "Software problem" on page 108 and the operating system documentation that comes with your computer. If you have installed software applications yourself, see the documentation that comes with the software.
