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.
BIOS Settings
Warning
Incorrect settings can
cause your system to
malfunction. To correct
mistakes, return to
Set-
up
and restore the
Opti-
mized Defaults
with
<F3>
.
UEFI Boot & POST
When UEFI Boot is en-
abled, then the prompts
to
press F2 or F7 will
not appear
. However
you can still press F2 to
enter the setup, or F7 to
choose the preferred
boot device, if you press
the key immediately the
system boots up.
