Problem Solving
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.
