The Power-On Self Test (POST)
If you enable the Boot-time Diagnostic Screen in the Setup Utility, each time you
turn on the computer the system takes a few seconds to conduct a POST, including
a quick test of the on-board RAM (memory).
As the POST proceeds, the computer will tell you if there is anything wrong. If there
is a problem that prevents the system from booting, it will display a system summary
and prompt you to run Setup.
If there are no problems, the Setup prompt will disappear and the system will load
the operating system. Once that starts, you can’t get into Setup without rebooting.
