Starting Your Personal Computer Note: If your computer is configured correctly, it can be started remotely over a network. For more information, see "Wake on LAN" on page 58. 1. Turn on all external devices, and then turn on your computer. Numbers showing the amount of memory being tested appear in the top-left corner of the screen until the total amount of memory in the system is reached. Your computer is running the power-on self-test (POST). Options for running a fast POST or accessing the Configuration/Setup Utility program appear in the lower-left corner of the screen. If POST finishes without detecting a problem, you hear one beep, and the first screen of your operating system or application program appears (if you have not set a power-on password). If you have set a power-on password, complete step 2. 2. If you have set a power-on password, a prompt appears on the screen. If you have set both power-on and administrator passwords, you can type either password at the password prompt. (Refer to "Passwords" on page 44 for instructions on setting and using passwords.) Type your password at the prompt and press Enter. The first screen of your operating system or application program appears. Note: If POST detects a problem when you start your computer, you hear multiple beeps or no beep. In most cases, an error code appears in the top-left corner of the screen, and in some cases a description of the error is displayed beside the code. (Note that the screen will sometimes display multiple error codes and descriptions.) Write down all error code numbers and descriptions. For information on what caused an error message to appear and what action to take, refer to "Solving POST Error Message Problems" on page 68 and "POST Message Charts" on page 71. If you hear no beep during POST, refer to "Troubleshooting Charts" on page 89. You might need to have your computer serviced. Using a Mouse A mouse is a device that you use to point to and select objects on the monitor screen. The mouse connects to your computer by a cable. Some mouse devices are designed for the round mouse connector on the back of your PC; other mouse devices are designed for the D-shaped serial connector. You can use either type of mouse, if the correct software (device driver) is installed. Chapter 3. Operating Your Personal Computer 21
