Monitoring POST while it is running

Each time you turn on the system, the power-on self- test (POST) runs automatically and checks the system board, CPU, memory, keyboard, and most installed peripheral devices.

During the memory test, POST displays the amount of memory that it is able to access and test. Depending on the amount of memory, it may take several minutes to complete the memory test. If you do not want to wait for it to complete, you can terminate it by pressing CTRL+ALT+S.

Press F2 key if you want to run SETUP

If you do not press <F2>, the above message remains for a few seconds and the boot process continues.

If POST finds an error, it displays an error message and, in case there is a problem with the display, puts out a series of long and short beeps. Write down any beep code emitted. This information is useful to your service representative.

Refer to the BIOS User’s Information section in this chapter for a list of items to check for each error code and for an explanation of the error beep codes.

Table 6-1 lists keys active during POST and provides a description of errors that may occur.
