Familiarization Guide
HP Kayak XA Series
This guide is for experienced technicians who have already completed the HP
Kayak PC family training course. It assumes that the reader is already familiar with
the different HP Kayak models.
This document is a self-paced familiarization guide designed to train you to repair
the PC. It contains information specific only to the repair of the HP Kayak XA
Series 0503 and 0541 Desktop and Minitower PC Workstations with the HP
MaxiLife feature.
For information on the installation of accessories, refer to the paper User’s Guide
and the online documents that are supplied with the PC.

How can I tell the difference between the latest HP Kayak XA model
(series 0503 or 0541), and the previous HP Kayak XA models?
There are two simple and quick ways to identify the latest HP
Kayak XA model. First, there is a label on the side of the PC
indicating “Series 0503” or “Series 0541”. Second, the latest
Kayak XA models are equipped with a single Pentium II
Deschutes processor for Slot 1.

The connector layout on the system board is the same for HP Kayak XA
Series 0503 and 0541 desktop and minitower models.
However, on the minitower models, there is one connector for the LCD

System Board Switches
System Board Switches
The first system board switch is reserved and should always be set to its
default setting. Switch 1 enables the PC Workstation to be fully compliant in
terms of electromagnetic emissions (clock dithering spread spectrum mode:
the processor clock frequency is moving slightly around its normal
frequency, less than 0.5%).
This implies that the electromegnetic emission pike at frequency processor
is less important. One potential drawback is that around (normally less than
1%) of performance can be lost. This switch is not documented in any of the
user guides and should never change from the default setting.
The next four switches (2 to 4) are used to set the ratio of processor-
frequency to Processor-Local-bus-frequency. The last five switches (5 to 10)
are used to set the configuration for the PC Workstation.
NOTE On the desktop model, there is a System Board Switch label located above
the CD-ROM cage.

HP MaxiLife Utility
HP MaxiLife Utility
HP MaxiLife is a hardware monitoring chip which is resident on the system
board. This chip receives data about the various system components via a
dedicated I2C bus. If it detects a potential error or that a component is in an
error state (for example, there is a CPU failure), it displays a warning with a
flashing LED and message on its LCD that specifies which component has
the problem.
Due to HP MaxiLife’s system independent design, even if there is a serious
component failure, it remains in operation and is able to indicate what the
problem is via the LCD.
For the HP MaxiLife to work correctly, the PC Workstation must always be
connected to a grounded outlet. This enables the PC Workstation’s hardware
monitoring chip to be active, even if the system has been powered off.
The following diagram shows where the LCD is located on the HP Kayak
XA Series 0503 and 0541 desktop and minitower PC Workstations.

HP MaxiLife Utility
The following menus are available on the HP MaxiLife utility when pressing
the menu button:
•System Info. Obtains information from the BIOS and the system’s Serial
EEPROM from a previously successful boot. This information includes:
product name (HP Kayak XA) BIOS version, serial number, the number of
processors and speed, size of memory for each DIMM socket.
•Boot Steps. Shows the Power-On Self Test (POST) codes during the
system startup. The POST code is provided by the BIOS and is displayed
on the LCD panel as soon as it is available. If the system stops during the
startup, the last successful boot step POST code is displayed on the LCD.
•Diagnostics. Runs a set of diagnostics assessing the system’s
components. Results of the tests OK/FAIL are displayed on the LCD one
after another when the user presses the button.
Error Messages
When the PC is turned on (pressing the ON/OFF button), the system
initiates the normal startup sequence. A first diagnostic (called pre-boot
diagnostics) is run to check the presence of the processor, DIMM and power
supply.
MaxiLife does not purposely ‘freeze’ the system if an error is detected.
However, some critical hardware errors are fatal to the system and will
prevent the system from starting (for example, ‘Power’, ‘Board PLL’ are
serious malfunctions that will prevent the CPU from working correctly).
Errors that are not so critical (for example, ‘CPU Socket’ for missing
processor and ‘NO RAM’) are also detected by the POST and will abort the
boot process after beeping. The ‘RAM type’ error, however, is only detected
by POST, with the same abort process.
Finally, while the PC is working, fan and temperature checks are conducted
continuously and any anomaly reported (for example, a fan error when a
cable is not connected). This type of error disappears dynamically when the
problem has been fixed (for example, the fan cable has been reconnected).

19
HP MaxiLife Utility
If an error is detected, a screen appears on the LCD panel. The following
table shows the test sequence carried out, the type of error message, and
the action to take.The errors mentioned correspond to standard error codes
(they are displayed without you having to press a key on the LCD status
panel).
Test Error Code Action to Take
1When pressing one of the LCD status
panel buttons, nothing is displayed.
2When the system is powered on, nothing is
displayed.
LCD status panel is
blank
• Check that the two cables to the LCD status panel are properly
connected (refer to the system board layout for position).
• Check that the PC’s power cable is plugged in.
Presence of CPU processor slot. CPU SOCKET • Check that the CPU is correctly installed in the processor
socket.
Monitoring of some voltages: 12V POWER SUPPLY • Check the power supply connectors, CPU.
The error message could also show: Power CPU.
Number of installed DIMMs NO RAM • Check that the memory module is correctly installed in the
memory socket.
Compatibility of DIMMs. The BIOS checks that
the inserted DIMMs are both compatible with
one another, and compatible with the Front Side
Bus frequency.
RAM TYPE • Check the installed memory modules. This error occurs when
mixing incompatible memory modules, for example, when
installing a 66 MHz DIMM on a 350 MHz or higher system, or
when mixing Unbuffered and Registered memory modules.
System board clock generators (PLL). BOARD PLL • Check the power supply connector.
• Replace the system board (PLL clock generator).
Monitoring of power signals to the CPU. This
checks the entire power system from the power
supply outlet to the CPU.
POWER • Check that the processor is correctly installed.
• Check the power supply unit connectors.
Availability of video board. 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.
NO VIDEO • Check that the video board is correctly installed.
Note: No error is detected if a monitor is not connected to an
installed video board.
Check on ability of CPU 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.
BIOS • 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.
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.
POST XXXX • If the screen is working, you can obtain the meaning 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.

HP MaxiLife Utility
Special Cases 1If a CPU is not installed correctly.
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.
2Only one pre-boot error reported on the system.
Hidden errors will be revealed when the current error has been fixed.
3If a “No Video Error” message is displayed, even though the video is
working correctly.
With some specific add-on boards, this error may appear even when
the system is working correctly. To check if this is the case, remove all
add-on boards from the basic system configuration.
1. Special cases: Board PLL = System board needs replacing. CPU error = Reset or power off the system to recover.
During normal usage of the PC, HP MaxiLife
continuously checks vital parameters of the
system. If an error occurs, a message is
automatically displayed on the LCD panel.
FAN CPU • 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
error”.1
