Test
1 When pressing one of the LCD status
panel buttons, nothing is displayed.
2 When the system is powered on, nothing is
displayed.
Presence of either CPU or Terminator in the
processor slot.
Control of some voltages: VRMs, 12V
Number of installed DIMMs
Compatibility of DIMMs. The BIOS checks that
the inserted DIMMs are both compatible with
one another, and compatible with the Front Side
Bus frequency.
Check the system board clock generators (PLL).
Test of the correct power signals to the CPU.
The power supply may be OK, whereas the VRM
is not.
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.
Error Code
LCD status panel is • Check that the two cables to the LCD status panel are properly
blank connected (refer to the system board layout for position).
• Check that the PC's power cable is plugged in.
CPU SOCKET • Check CPUs and Terminator and VRM of installed processor.
POWER SUPPLY • Check the power supply connectors, VRM, CPU. In a single
processor system, check that the VRM is not plugged into the
terminator socket.
The error message could also show: Power CPU1 and Power
CPU2.
NO RAM • Check that the memory module is correctly installed in the
memory socket.
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.
BOARD PLL • Check the power supply connector.
• Replace the system board (PLL clock generator).
POWER • Check that the VRM, processor and terminator are correctly
installed.
• Check that the VRM is not plugged on a socket with a
terminator (this could be the likely cause).
• Check or replace the VRM.
• Check the power supply unit connectors.
NO VIDEO • Check that the video controller is correctly installed.
Note: No error is detected if a monitor is not connected to an
installed video controller.
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.
