  • 32 bit Windows Vista® Business OS downgrade to Windows® XP Professional 32 bit OS
  • 64 bit Windows Vista® Business OS downgrade to Windows® XP Professional 64 bit OS
  • 64 bit Red Hat Enterprise Linux OS

Despite the above operating systems which usually pre-loaded are outdated.

But still, hp z800 workstation is a good option and perform better than lots of workstation of its range.

The good news is that the latest Windows 10 operating system and its parallel other operating systems (OS) like 64 bit Suse Linux Enterprise, 64 bit Red Hat Enterprise Linux supported very well.

Driver support also still available for these latest operating systems so no need to worry if you have such a workstation.

Hp z800 is still worth your money because its performance on the latest operating systems also outstanding.

Basic Troubleshooting LED Codes

The sequence of beeps and led blinking of the workstation at the time of start gives very useful information regarding diagnosing the issue.

Also important to make diagnose remotely or at least narrow down the suspected issue.

As per hp z800 specs at the time of workstation power on the very first step is to run Power On Self Test (POST).

On the failure of during test beep and led blinking status to represent the issue in that section to execute the POST test successfully.

Beep sound comes from the front panel chassis speaker for five cycles only. After that LED light (upside from power on button) blinks without a beep sound.

Case One

When the system boots normally after finishing all the POST test indicate one beep sound and one led blink.

Case Two

When Red LED blinks two times and beep sound two times with the cycle of one per second. Between the cycle is a two-second pause.

Diagnose :

Clearly indicate system and its component have not proper cooling. In other words, the workstation fan is not working.

Troubleshoot :

Step One :

First, visually inspect the airflow path of the workstation is not blocked. If blocked then make it clean then turn it on to verify the problem solved or not.

Step Two :

If the problem persists then open the workstation side cover (details as mentioned above in hp z800 specs component section).

Remove the inner air guide to inspect inner fans. Verify system fans, Ram cooling fans, and processor heat sink fans are running. Also, ensure the heat sink is properly seated on processors.

In case any of the fans are not running then check its power connector and reconnect if required otherwise replace the defective fan.

Case Three

Red LED blinks and beep occurs three times on power on. As mentioned above once in a second and two-second pause.

Diagnose :

Signify that processor related issue or not installed.

Troubleshoot :

Step One :

Open side cover of workstation, remove air guide, remove heat sink fan connector, and takeout heat sink.

Step Two :

Make sure the processor is installed. If not then install as per hp z800 specs.

Step Three :

When a processor is present then try to remove and place it again. Fix other components in proper manner and power on.

Step Four :

After re-seat processor problem continues need processor (tested working) replacement as per hp z800 specs.

Step Five :

Even processor replacement never works replace the motherboard as per hp z800 specs.

Case Four

Four beeps and four red LED blinks at the cycle of one per second and two-second pause before repeating the cycle.

Diagnose :

Indicates one or more power supply output failed otherwise its routing path is missing.

Mostly power supply outputs are directly routed through the motherboard.

Here need to isolate the defective component or device with the following steps.

Troubleshoot :

Step One :

Disconnect the workstation AC power supply plug from the back panel connector.

Open the left side panel along with all air guides so that can access all the devices or components.

Visually inspect every component of the workstation for any abnormality like burning sign or smell.

It makes it a lot easier to point out the problem and save time.

Ensure all the power supply connectors on the system board (motherboard) are properly connected.

Remove and reconnect if seems to be required.

Check and verify problem solved or not.

Step Two :

Remove all the devices at once but reconnect one by one. Observe the changes by attaching each device.

Thus can isolate the defective device witch is dropping the power supply.

Step Three :

In the previous step never get succeeded then need to cross-check power supply functionality.

The very first movement disconnects all the power supply output connectors from the motherboard (system mainboard) and peripheral devices.

Before performing the above steps make sure the AC input power cable is removed.

Now after removing all outputs of power supply connect input AC power supply plug.

Here need to verify the power supply fan is spinning and LED glowing.

Either fan not spinning or led not glowing then replace power supply otherwise replace system mainboard as per hp z800 specs.

Case Five

Red LED blinks and beep five times and frequency is 1 per second. For repeating 2 second’s pause.

Diagnose :

Definitely indication of pre-video memory error.

Troubleshoot :

Step One :

Remove left side panel cover, air guide, and Ram cooling fan assembly to access the ram modules.

Check every memory module properly seated. Remove ram modules clean it’s contacts and socket. After cleaning place it again properly then power on again.

Step Two :

No luck in the first attempt then replace the RAM module one by one and check for problem resolution. RAM module must be as per hp z800 specs.

Step Three :

Otherwise need to change the system board (Motherboard) if the above solutions never worked.

Case Six

The LED blinks red and beep sound six times at the frequency of one as said before two-second gap between two cycles.

Diagnose :

Here symptoms indicate pre-video graphic card issue.

Troubleshoot :

Step One :

Try to remove and reseat the graphic card and careful about its power connector.

Step Two :

Secondly replace the graphic card according to hp z800 specs.

Step Three :

Thirdly and final step is to replace the system’s mainboard (motherboard).

Case Seven

A beep sounds 7 times and Red Led blinks seven times remaining conditions are the same as before.

Diagnose :

Symptoms indicated system board (motherboard ) failure detected by ROM.

Troubleshoot :

Step One :

Very first step is try to reprogram flash ROM.

Step Two :

Otherwise replace system board as per hp z800 specs.

Case Eight

Blinking of red LED eight times simultaneously beep sound eight times at the rate of one beep per second and two-second break then repeat.

Diagnose :

Denote System ROM has a bad checksum, therefore, entering in failsafe boot block recovery mode.

Troubleshoot :

Step One :

Reprogram the flash ROM.

Step Two :

Otherwise replace the system board (motherboard).

Case Nine

Nine-time red LED blinks and beep sound one beep per second and two seconds pause before repeat.

Until seven cycles later beep sound goes off and only red LED blinks.

Diagnose :

Represents that system is turning on but not able to boot completely.

Troubleshoot :

Step One :

Firstly try to replace processor as per hp z800 specs.

Step Two :

Otherwise replace main system board as per hp z800 specs.

Note: During the service of the hp z800 workstation body should be well connected to the ground to protect components from static charge. Be aware and careful while the AC power plug is connected to a workstation. Do not work while consuming alcohol.
