Test
Availability of video controller. It is also checked
by the BIOS. If an error is detected, it is not a
fatal one and the BIOS will continue its
execution normally.
In order to detect whether the CPU is able to run
a given code, HP MaxiLife waits for a
synchronization event from the BIOS. Any failure
that prevents the execution of the firmware will
trigger an error.
The BIOS then executes the Power On Self Test
(POST) sequence. In this phase, HP MaxiLife
waits for any error messages that the BIOS may
issue.
During normal usage of the PC, HP MaxiLife is
always checking vital parameters of the system.
If an error should occur, a message would be
automatically displayed on the LCD panel.

Special cases: Board PLL = System board needs replacing. CPU error = Reset or power off the system to recover.

1 If a CPU is not installed correctly.
Either the "Power CPUx" or "CPU socket" or "BIOS" message may
appear. This will depend on which end of the CPU connector is not
correctly inserted.
2 If a VRM is installed and there is a terminator in the associated CPU
socket.
MaxiLife displays "Power" error message and the system does not start
3 Only one pre-boot error reported on the system.
Hidden errors will be revealed when the current error has been fixed.
4 If a "No Video Error" message is displayed, even though the video is
working correctly.
With some specific add-on boards (for example, 1540 from Adaptec
with SCSI BIOS), this error may appear while the system is fully work-
ing. To check if this is the case, remove all add-on boards from the ba-
sic system configuration.

Action to Take
• Check that the video controller is correctly installed.
Note: No error is detected if a monitor is not connected to an
installed video controller.
• Flash the latest version of the system BIOS by using the system
recovery procedure. Set switch 10 to the down position.
• Check that the RAM is correctly installed.
• Check that the CPU is firmly inserted.
• If the screen is working, you can obtain the signification of the
error by typing "Enter" at the end of the POST. Or, you can
check the list of errors that are available on the HP World-Wide
Web support page.
• Check the connection of the corresponding component, which
could be: "Temp IO slot", "Power errors, "Fan CPU", "Board
PLL", "Temp disk", "Temp CPU", "Fan disk", "Fan IO slot", "CPU
1
error".
