your call, follow these steps:
1. Write down a description of the problem, including the error messages and
the number of the tests or utilities that failed.
2. Look at the status LED display on the back of the system unit and write
down the numbers of the LEDs that are lit (see Figure 1–3).
3. List the steps you took to correct the problem as well and their results.
4. Write down the serial and model numbers of the system unit and any
connected peripheral devices. These numbers are usually printed on a
label on the back of the device.
