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
Power Button/Power Button LED
The following table describes the LED states for the Compaq 500B and 505B MT Desktop PCs.
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 casesensitive), the system supports the dual-color power button LED and therefore, the BIOS
support as described above is required.

BIOS Updates
1. Turn off the computer and any external devices, and disconnect power.
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:
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.
1. Click Start > Shut Down.
6. Replace the jumper on pins 2-3.
2. Select Restart, and then click OK.
7. Reinstall the battery.
8. Replace the access panel, external devices, and reconnect the power cord.
3. When the first screen displays, press F10 to enter Setup. The BIOS revision number is listed
on the main menu.
9. Turn on the computer.
4. Write down the current BIOS version.
10.Hold down the F1 key during boot and enter BIOS setup to re-enter data.
5. Exit Setup by pressing Esc, selecting Yes, and pressing Enter.
HP Insight Diagnostics
POST Error/Warning Messages
The HP Insight Diagnostics utility can be used to view information about the hardware configuration of the computer. It can also perform hardware diagnostic testing on the computer and its
subsystems, which provides information for troubleshooting.
HP Insight Diagnostics runs from the recovery discs. To access HP Insight Diagnostics, the user
must first create a set of recovery disks from the recovery image on their hard drive. Then they
can access HP Insight Diagnostics by booting from the recovery disc that contains the utility.
To create a set of recovery discs, users need to perform the following steps.
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. Click Start > HP Backup and Recovery > HP Backup and Recovery Manager.
2. Click Next to open the Backup and Recovery Wizard.
3. Select Create to create a set of recovery discs, and the click Next.
4. Follow the wizard instructions to create a Recovery Disc Set.
5. Use Windows Explorer to search the Recovery Disc Set for the CD in the /Hpdiags directory.
6. Insert the CD into the optical drive on the computer.
7. Restart the computer and the system will boot to the CD.
8. Click the appropriate language and click Next.
9. Click Agree in the End User License Agreement page. The utility launches with the Survey
tab displayed.
1.Handle the first serious error, SMART error, as follows:
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
Compaq 500B, MT
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.
