System doeIf there is one DIMM in the system the memory row/bank may be disabled when there is a memory failure. The system will not boot because it has no memory to use. If the DIMM is replaced with one of the exact same type and size, then the system will continue not to boot. BIOS cannot tell when a DIMM has been replaced with one of the exact type and size, therefore BIOS believes it is still the bad DIMM and will not use it.

Here are two possible workarounds:

1. After replacing the defective DIMM, continue to reboot the system until you hear the "no memory" post beep sequence (3-3-3) during POST (no video display). After three (3) incomplete boots, a "062 three consecutive boot failure. Using default CMOS configuration caches are off" error will occur. At this point BIOS will go back to the default settings and begin to use the new DIMM. However, if you have disabled the 3 boot fail count (this setting may not be available in all servers) in Setup, then BIOS will not turn the DIMM row/bank back on.
-=OR=

2. Remove the DIMM. Power on the system until the "no memory" post beep sequence (3-3-3) is heard. The memory row/bank will now be marked as being empty. Power off the system and put a good DIMM back into the system. The memory DIMM row/bank is re-enabled and the system boots normally.

NOTE: If more than one DIMM (or more than one DIMM set) is installed in the server and one memory (or one memory set) row/bank is disabled due to a memory failure then, the user must go into setup and re-enable the row/bank after replacing the bad DIMM.

Hello Hardyjosef,
Below is the beep code chart for the mini 10 systems.
No POST
If the system does not perform a Power-On Self-Test, there are various things to look for:
1.Check that the system has a power light.
2.If the system has no power light, ensure it is plugged into AC power. Remove the battery.
3.If the system has power but is not performing a POST, Check for one of the following Beep code errors.
Beep Code Description Failure Coverage
1 BIOS ROM checksum in progress or failure. BIOS Chip Motherboard Failure or ROM Error
2 No RAM Detected No Memory Detected
3 Chipset Error (North and South Bridge Chipset, DMA/IMR/Timer Error for Intel platform); Chipset Error Motherboard Failure
Time-Of-Day Clock test failure.
Gate A20 Failure
Super I/O Chip Failure
Keyboard Controller Test Failure
4 RAM Read/Write Failure Memory Failure
5 RTC Power Fail. COMS Battery Failure
6 Video BIOS Test Failure Video Card Failure
7 CPU Cache test failure CPU Failure
8 LCD LCD Failure
4.With the power off and the system unplugged, remove all CRUs from the system and reconnect the AC adapter to the system and try again.
Try reseatting the memory to see if that will resolve the issue. If not, the motherboard may be bad and will need to be replaced. If you need another motherboard you can call the Dell Spare Parts Department at 1-877-717-3355 to purchase one.

One of your memory chips is bad.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Diagnostic Lights CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide. To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4"on the front or back panel. The lights can be off or green. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. If the POST portion of system boot completes successfully, all four lights display solid green. If the computer malfunctions during the POST process, the pattern displayed on the LEDs may help identify where in the process the computer halted.
NOTE: The orientation of the diagnostic lights may vary depending on the system type. The diagnostic lights can appear either vertical or horizontal.

Light Pattern

Problem Description

Suggested Resolution


The computer is in a normal "off" condition, or a possible pre-BIOS failure has occurred.
The diagnostic lights are not lit after the computer successfully boots to the operating system.
Plug the computer into a working electrical outlet and press the power button.


A possible BIOS failure has occurred; the computer is in the recovery mode.
Run the BIOS Recovery utility, wait for recovery completion, and then restart the computer.


A possible processor failure has occurred.
Reinstall the processor and restart the computer.


Memory modules are detected, but a memory failure has occurred.

• If you have one memory module installed, reinstall it and restart the computer. (see "Memory" for instructions on how to remove and install memory modules.)
• If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
• If available, install properly working memory of the same type into your computer.
• If the problem persists, contact Dell.

A possible graphics card failure has occurred.

• If the computer has a graphics card, remove the card, reinstall it, and then restart the computer.
• If the problem still exists, install a graphics card that you know works and restart the computer.
• If the problem persists or the computer has integrated graphics, contact Dell.

A possible floppy or hard drive failure has occurred.
Reseat all power and data cables and restart the computer.


A possible USB failure has occurred.
Reinstall all USB devices, check cable connections, and then restart the computer.


No memory modules are detected.

• If you have one memory module installed, reinstall it and restart the computer. (see "Memory" for instructions on how to remove and install memory modules.)
• If you have two or more memory modules installed, remove the modules, reinstall one module, and then restart the computer. If the computer starts normally, reinstall an additional module. Continue until you have identified a faulty module or reinstalled all modules without error.
• If available, install properly working memory of the same type into your computer.
• If the problem persists, contact Dell.

Memory modules are detected, but a memory configuration or compatibility error exists.

• Ensure that no special memory module/memory connector placement requirements exist.
• Verify that the memory modules that you are installing are compatible with your computer.
• If the problem persists, contact Dell.

An other failure has occurred.
This pattern also displays during System Setup and may not indicate a problem.

• Ensure that the cables are properly connected to the system board from the hard drive, CD drive, and DVD drive.
• Check the computer message that appears on your monitor screen.
• If the problem persists, contact Dell.

After POST is complete, all four diagnostic lights turn green briefly before turning off to indicate normal operating condition.
None.

hi,

nope this is not normal. I have a article included below from hp. read this and you will understand the problem and also some ways on how to fix it. The blinking lights is a code on where the system fail or what component that fails.

Hope this helps you.
Don't forget to rate me OK!
Thanks for using Fixya!

John

HP Black screen error codes

Support details

This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008.
On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes.
The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved.

Battery power LED blinks

The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition.

Battery low charge or failure
Battery power LED blinking Battery Insufficient charge on the battery

LEDs near Caps Lock and Number Lock keys blink when starting notebook
The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up.

If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition.
Knowing the number of blinks is helpful when you contact an HP support agent for technical help.
Caps Lock/Num Lock LED Component Tested Error Condition

LEDs blink 1 time CPU CPU not functional
LEDs blink 2 times BIOS BIOS corruption failure
LEDs blink 3 times Memory Module error not functional
LEDs blink 4 times Graphics Graphics controller not functional
LEDs blink 5 times System board General system board failure
LEDs blink 6 times BIOS BIOS authentication failure

Error code explanations
The sections below provide some common explanations for each error code listed in the table above.

AC Adapter not connected or battery low charge
When the computer is on battery power only and the AC adapter is disconnected, if the Battery Power and Caps Lock / Number Lock LEDs do not glow, there is either a very low change or no charge in the battery. Connect the AC power adapter, verify that the battery power LED glows, allow the battery to charge for 15 - 30 minutes and then attempt to start the computer. If it starts, run the battery test and calibrate the battery. If it does not start, if possible, connect a replacement battery to verify that the battery is the problem.

If the computer does not start after charging the battery, remove the battery and connect the AC power supply. Verify that the battery power LED glows, and then attempt to start the computer. If the LED still does not glow, either the AC adapter has failed, or there is a bad connection between the adapter and the system board. If possible, connect a different AC power adapter to verify that the adapter is the problem, or contact HP for support which may require a service event.

Insufficient charge on the battery
If the battery light LED (which looks like a lightning bolt ) flashes, the battery has insufficient charge to start the computer. To resolve this error, try the following solutions.

*
Connect the notebook PC to AC power and attempt to start the computer again.
o
Check the AC adapter to confirm that all of the plugs are securely seated.
o
Determine if the power LED on the AC adapter is lit (if available) to verify that the computer is receiving AC power from the wall outlet.
*
If the computer operates on AC power correctly, charge the battery for thirty minutes to one hour and then restart the computer.
NOTE: Charging the battery for this length of time is called "trickle charging". Trickle charging is a continuous constant-current charge at a low rate, which recharges the battery slowly when it is in a deep discharge state. Deep discharge occurs when a battery is left unused for extended periods of time.

The computer processor (Blink code 1) has stopped functioning properly. Contact HP for assistance.

BIOS corruption failure
If a BIOS corruption error occurs (Blink code 2), you may not even notice the blink codes, because as soon as the computer recognizes the error, it restarts, attempts to recover the BIOS, and then restarts again. You may notice an extra-long startup process as a result, and a message indicating that the BIOS has been recovered may display on startup. If this occurs, update the BIOS on the computer. For more information, refer to the HP Notebook PCs - Locate and Install Updated BIOS, Drivers, and Software .

Module error not functional
If you experience a memory failure (Blink code 3), follow the guide in the table below.
If Using Original Memory If New Memory Is Added
Reseat the memory.

If reseating the memory does not resolve the problem, try replacing the memory with new memory. Reseat the memory.

If you continue to experience this error code after reseating the memory, the problem may be with the memory itself. Take the new memory out of the computer, put the original memory back into the computer, and then retest it.

If you do not feel comfortable reseating the memory yourself, take the computer to a computer retailer and ask them to reseat it for you.
NOTE: Some memory module errors may allow the computer to start but will then cause the computer to restart and display a blinking error code.

Graphics controller not functional
If you experience a graphics controller failure (Blink code 4), contact HP for assistance.

General system board failure
A general system board failure (Blink code 5) is the failure of a component not covered by the other LED error codes. Contact HP for assistance.

BIOS authentication failure
The BIOS authentication error (Blink code 6) is extremely rare. It is the result of a discrepancy between the BIOS and the hardware that is installed on the computer. This error occurs when the BIOS cannot authenticate signatures from the hardware on the system. The purpose of the BIOS authentication is to be sure that no one has tampered with the BIOS on the computer.
If a BIOS authentication failure occurs, the computer automatically performs a BIOS recovery. If the computer does not automatically recover the BIOS, manually perform a BIOS recovery. To manually perform a BIOS recovery, press all four arrow keys at the same time to cause the BIOS to go to the EFI partition to find and recover the current BIOS.
