System Board

Diagnostic Beep Codes

The Power-On Self-Test (POST) is a series of diagnostic tests that runs automatically when the

computer is powered on. If the POST detects an error, this causes an audible beep code to sound.

The POST beep codes are not necessarily accompanied by an associated, visible error code or

text message.

The following table shows the POST beep codes, their meanings, and the recommended actions

for solving the problem.

LED Codes

The following table describes the LED states for the HP 500B, Compaq 500B, and 505B MT

Desktop PCs.

Clearing CMOS

The header allows you to clear the RTC RAM in CMOS.

To erase the RTC RAM:

1. Turn off the computer and any external devices, and disconnect power.

2. Remove the access panel.

3. Remove the RTC battery.

4. Locate the CMOS jumper header on the motherboard. It is labeled E18.

5. Remove the jumper from pins 2-3 pins and put it on pins 1-2 to clear CMOS. Keep the cap on

pins 1-2 for 5 to 10 seconds.

6. Replace the jumper on pins 2-3.

7. Reinstall the battery.

8. Replace the access panel, external devices, and reconnect the power cord.

9. Turn on the computer.

10.Hold down the F1 key during boot and enter BIOS setup to re-enter data.

Hewlett-Packard Vision Diagnostics

The Hewlett-Packard Vision Diagnostics utility allows you to view information about the hard-

ware configuration of the computer and perform hardware diagnostic tests on the subsystems of

the computer. The utility simplifies the process of effectively identifying, diagnosing, and iso-

lating hardware issues.

Use HP Vision Diagnostics to determine if all the devices installed on the computer are recog-

nized by the system and functioning properly. Running tests is optional but recommended after

installing or connecting a new device.

To access HP Vision Diagnostics, you must create a Recovery Disc Set then boot to the CD con-

taining the utility. It can also be downloaded from http://www.hp.com and either burned to CD

or installed to a USB flash drive.

1. In Windows Explorer, go to C:\SWSetup\ISOs and burn the file Vision Diagnostics.ISO to a

CD or copy it to a USB flash drive.

2. While the computer is on, insert the CD in the optical drive or USB flash drive in a USB port.

3. Shut down the operating system and turn off the computer.

4. Turn on the computer. The system will boot into HP Vision Diagnostics.

NOTE: If the system does not boot to the CD in the optical drive or to the USB flash drive,

you may need to change the boot order in the Computer Setup (F10) utility.

5. At the boot menu, select either the HP Vision Diagnostics utility to test the various hardware

components in the computer or the HP Memory Test utility to test memory only.

NOTE: The HP Memory Test is a comprehensive memory diagnostic utility that is run as a

stand-alone application, outside of HP Vision Diagnostics.

6. If running HP Vision Diagnostics, select the appropriate language and click Continue.

7. In the End User License Agreement page, select Agree if you agree with the terms. The HP

Vision Diagnostics utility launches with the Survey tab displayed.

Using the Setup Utility

The BIOS Setup Utility is accessed by pressing the F10 button during startup. The BIOS Setup

Utility allows you to:

• Change factory default settings

• Set the system date and time

• Set, view, change, or verify the system configuration, including settings for graphics, audio,

storage, communications, and input devices

• View processor and memory settings

• Modify the boot order of bootable devices, such as hard drives, diskette drives, optical

drives, or USB media

• Run tests on the hard drive

• Establish a supervisor password that controls access to the Setup Utility

Power Button/Power Button LED

The power button is under the BIOS control during POST, in BIOS Setup and after booting to a

non-ACPI OS. The BIOS must respond immediately when the power button is pressed in these

environments. For the ACPI-compliant OS such as Windows, the BIOS must pass the power

button information to the OS via the ACPI table as specified in the ACPI spec.

If a platform offers a dual-color-based power button LED, the BIOS will program the power

button LED to alternate the color between the On (ACPI S0) state and the Stand-by (S3) state. In

doing so, the LED should not blink, but stay constant. Check with the corresponding platform

manager for the default colors in the On and Stand-by states. The color of the power button LED

in the Hibernate state (ACPI S4) is the same as in the S5 state.

To find out if the system's power button LED is dual-color capable, check the SMBIOS Type 11

data structure. If the SMBIOS Type 11 data structure contains the string DLED (NOT case-

sensitive), the system supports the dual-color power button LED and therefore, the BIOS

support as described above is required.

BIOS Updates

HP periodically releases system BIOS updates, which are available from the HP web site. These

updates often contain fixes for known issues in the BIOS.

To find out whether a PC needs a BIOS update, compare the current BIOS version number

against the latest version available for download. To determine the current BIOS version, you

should perform the

following steps:

1. Click Start > Shut Down.

2. Select Restart, and then click OK.

3. When the first screen displays, press F10 to enter Setup. The BIOS revision number is listed

on the main menu.

4. Write down the current BIOS version.

5. Exit Setup by pressing Esc, selecting Ye s , and pressing Enter.

POST Error/Warning Messages

Once the display becomes available, the BIOS should classify all errors detected during POST

into 3 categories and handle them as specified below:

• Critical errors requiring system shutdown (e.g. CPU fan fault):

Clear the screen, display the corresponding error message, pause for a while as specified and

then turn the system off.

• Serious errors requiring user's attention and response (e.g. SMART error during POST):

Display the corresponding error message, wait for the user's input and then proceed as

selected.

• Alerts/warnings requiring user's attention (e.g. CMOS checksum error -> defaults loading):

Display the corresponding message and pause for a while as specified. If the message

includes an option for a keystroke from the user and the user responds with the key input,

proceed as selected. Otherwise, continue the POST process.

When there are multiple errors happened during POST, apply the following guideline:

• If multiple errors include at least one critical error, the system will shut down immediately

after handling the first critical error.

• If multiple errors do not include a critical error, handle all serious errors first, one by one,

and then proceed to alerts/warnings. For example, if the BIOS detected a SMART error

(serious error), a floppy diskette failure (serious error) and a CMOS checksum error (alert/

warning) during POST, the BIOS will handle them as follows:

For SKUs including an OS=MSV or an OS=LX in the SMBIOS Type 11 data,

1.Handle the first serious error, SMART error, as follows:

Display "xxx: Hard disk failure is imminent... Press F10 for Setup, F2 to Continue." If the

user selects F10, proceed to Setup. However, if the user selects F2, the BIOS should

proceed to step 2 below.

2.Handle the second serious error, floppy diskette failure, as follows:

Display "Floppy diskette failure... Press F10 for Setup, F2 to Continue." If the user selects

F10, proceed to Setup. However, if the user selects F2, the BIOS should proceed to step 3

below.

3.Handle the alert/warning message, CMOS checksum error, as follows:

Display "Default BIOS settings have been loaded... Press F10 for Setup, F2 to Continue”.

If the user selects F10, proceed to Setup. However, if the user selects F2, the BIOS should

proceed to step 2 below.

For all other SKUs, use F1 instead of F10 in the above handling.

NOTE: If a device fails to respond while the BIOS tries to configure the device during POST,

the BIOS must not make the system look as if it locked up by having an infinite loop or waiting

for too long. Instead, the BIOS must time out after a reasonable amount of time (the time varies

with the device) and skip to the next process.

NOTE: Unless specified in this document as above, the BIOS should not stop the POST process

with any POST diagnostic screen and/or error message to draw user’s attention. For example,

HP does not consider replacing a hard drive or CPU as an error condition.
