As an ENERGY STAR partner, HP has determined that this product meets the
ENERGY STAR guidelines for energy efficiency (Windows 2000, Windows 98 and
Windows 95 only).
Low power consumption (4.8W in suspend mode) can be achieved when
Suspend to RAM is activated. This can be done with ACPI operating systems
only (Windows 98 and Windows 2000). To activate Suspend to RAM, enter
your BIOS Setup by pressing F2 during startup, then go to the Power menu
and make sure that the field Suspend to RAM is set to enabled.
When Suspend to RAM is not activated, or if it is activated in non-ACPI
operating systems, the power consumption in suspend mode will be around
25W.

Notes
Operating temperature and humidity ranges may vary depending on the mass storage devices
installed. High humidity levels can cause improper operation of disk drives. Low humidity ranges
can aggravate static electricity problems and cause excessive wear of the disk surface.
The power consumption and acoustics figures given in the tables above are valid for the standard
configuration as shipped. For more information, refer to the product’s data sheet at HP’s web
site: www.hp.com/desktop
When the computer is turned off with the power button on the front panel, the power
consumption falls below 3W, but it is not zero. The special on/off method used by these
computers considerably extends the lifetime of the power supply. To reach zero power
consumption in “off” mode, either unplug the power outlet or use a power block with a switch.

System Features
Main Memory
Main Memory
There are two 168-pin DIMM slots on the system board for installing main
memory. You can install 133MHz SDRAM modules. These are available in 64,
128, 256 and 512 MB memory modules. You can install only one 512 MB
module. A maximum of 512 MB is supported.
You can use ECC or non-ECC memory modules. However, single/multiple bit-
error processing is not done by the 815 chipset.
Processors
The VL400 is equipped with either a single Socket 370 Intel Celeron or socket
370 Intel Pentium III processor. Socket 370 is a conversion of Slot 1 (used
previously by Celerons and Pentium IIs) to a socket, running at the same bus
protocol as the Pentium II (the GTL+ bus protocol). The processor is
connected to the system board through a Plastic Pin Grid Array (PPGA) 370
Socket. The reduction in size achieved by the Socket 370 Celeron is due to
the integration of the L2 cache on the processor die. Like the Celeron
processor, the Pentium III comes in a 370-pin socket (PGA370) package.
To find out more about Socket 370 Celeron technology, refer to the Technical
Reference Manual - Vectra Technology.

System Features
Integrated Graphics Controller
Integrated Graphics Controller
Some models use the integrated Intel® 815 graphics controller for 2D and 3D
graphics. The Intel® 815 graphics controller uses Direct AGP and Dynamic
Video Memory technology.
The controller uses 9-10 MB of system memory for graphics purposes. You
can also install a 4 MB graphics memory extension (in the AGP slot) for a
total of 12 MB memory (8 MB system memory is used in this case). The 4 MB
memory extension can improve 2D and 3D graphics performance
significantly.

BIOS Overview
Order in Which the POST Tests are Performed
Order in Which the POST Tests are Performed
Each time the system is powered on, or a reset is performed, the POST is
executed. The POST process verifies the basic functionality of the system
components and initializes certain system parameters.
The POST starts by displaying a graphic screen of the Hewlett-Packard logo
when the PC is started.
Devices, such as memory and newly installed hard disks, are configured
automatically. The user is not requested to confirm the change. Newly
removed hard disks are detected, and the user is prompted to confirm the
new configuration by pressing
. Note, though, that the POST does not
detect when a hard disk drive has been otherwise changed.
During the POST, the BIOS and other ROM data is copied into high-speed
shadow RAM. The shadow RAM is addressed at the same physical location as
the original ROM in a manner which is completely transparent to applications.
It therefore appears to behave as very fast ROM. This technique provides
faster access to the system BIOS firmware.
The following table lists the POST checkpoint codes written at the start of
each test.

BIOS Overview
HP e-DiagTools Preboot Diagnostic (Beep Codes)
HP e-DiagTools Preboot Diagnostic (Beep Codes)
When your PC starts up, its BIOS performs a Power-on Self Test (POST) to
test your hardware configuration for any problems. If a problem is detected
during the POST, an error is displayed on your PC’s monitor.
If, however, your PC is unable to display an error message (for example, when
you graphics controller has failed), it will emit a buzzing sound. This is the e-
DiagTools preboot diagnostic. Immediately after the buzzing sound, a series
of beeps is emitted.
If you hear a series of beeps, you should count them as this will help you
detect the cause of the problem.

System OK
Processor absent, not correctly connected or ZIP socket not closed
Power supply is in protected mode
No memory, bad memory modules, incompatible memory module
Graphics card problem
PnP/PCI initialization problem
Corrupted BIOS. You need to activate crisis recovery procedure.
Defective system board
Note that for Memory (code 3), Video Card (code 4), and PnP/PCI (code 5)
errors, e-DiagTools preboot diagnostic will only detect them after a 15-second
timeout.
If you miss the beep code, turn off the PC. Then press the on/off power
button for five seconds or more, then listen for the signal again.
The e-DiagTools preboot diagnostic, as well as emitting a beep sequence, also
encodes troubleshooting information (such as the PC models, serial number,
and failing component) into a coded audio signal. During a support call, this
coded signal can then be decoded by the HP Service Provider to provide
immediate and effective assistance.
