BIOS Beep Codes For HP Desktop at startup

Posted by Unknown Minggu, 10 November 2013 0 komentar

This document pertains to HP and Compaq All-in-One and TouchSmart Desktop PCs.

It is normal for the computer to make one or two short beeps during the startup process. However, if the computer beeps and Windows does not start properly, a more serious hardware problem exists. The most common problems that cause beeping sounds are:

Memory and heat-related failures caused by a build-up of dust in critical cooling areas

A keyboard key is stuck

A memory DIMM or hard drive cable is not seated properly

A component on the motherboard has failed

A basic computer function was unable to start

What to do when beep codes occur

Listen to the beeping sound and write down the number of beeps before each pause, if the beeps are long or short, or if the beeps high or low in tone. Once a pattern is determined, use the following beep code table to identify which component might be causing the problem:

NOTE:Not all beep codes are shown. For a complete list of beep codes, refer to beep code table specific to the motherboard of the computer. To find the motherboard information, go to the HP Support Web site , enter the computer model number, and then search for product specifications .

Use these codes to help troubleshoot problems related to system startup or flashing BIOS memory (such as in BIOS upgrades). When troubleshooting further, refer to the section What to do when beep codes occur . Four series of beeps indicate a fatal error; that is, a problem exists which prevents the computer from starting. For example, there might be two beeps, a short pause, one beep, a short pause, one beep, a short pause, and then three beeps; this is represented as 2-1-1-3 in the chart below.

NOTE: The following codes can vary depending on BIOS version.

Beeps	Description
1 short beep and 1 long beep	Memory problem
2 short beeps and 1 long beep (repeats 5 times)	Unable to initialize video or video card required but not installed
3 short beeps and 1 long beep	CPU configuration error or CPU type is not compatible

The following beep codes can occur while restoring, flashing or updating the BIOS:

Beeps	Description
1 short beep	Legacy floppy drive or CD/DVD drive not detected
2 short beeps	Floppy diskette or compact disc not detected
3 short beeps	Unable to start flashing (such as when missing a utility or BIOS image)
4 short beeps	Flashing failed (checksum error, corrupted image, etc.)
5 short beeps	BIOS recovery successful

Perform the following steps to resolve beeping issues. Before starting a task, turn off the computer, and then remove the power cord. After completing a task, replace any covers, reconnect the power cord, turn on the computer, and then listen for a beep code.

Remove any media from the floppy drives, CD/DVD drives, USB ports, and memory card reader slots, and disconnect all non-essential devices (printers, scanners, external hard drives, and similar).
Disconnect the mouse and keyboard, and then restart the computer. If the beeping sound stops, repair or replace those devices.
Hot air can damage internal components! Remove any obstructions that block vents. Clean the cooling vents on the case to remove dust. If cooling fans stop spinning or make strange noises, service the computer.
Figure 1: Hot air is released from case vents (your case may look different)
Remove the memory cover, and then reseat all memory modules. If the computer stops beeping, a memory module might not have been fully seated or connected.
If the computer has multiple memory modules, turn on the computer with only one memory module installed. If the computer stops beeping, the memory module might be defective, or might be the wrong type of memory for the motherboard. Reinsert the memory into the socket to see if a connection was the problem; otherwise replace the module. Repeat this process for all memory modules installed in the computer.
If all of the above steps have been tried and the beeping sound still exists, refer to beep code table specific to the motherboard of the computer, or Contact HP (in English) for additional assistance.

Digital life style is coming. PC, notebook, internet, these terms has familiar for our ears. Many people should buy PC or notebook because one some reason such as "job equipment requirement" or just for life style such as for internet access or maybe for gaming. How choose your PC or notebook for your need?

Panasonic Thoughbook

Apple Macbook

Below are some tips "How to buy a PC or Notebook":

Before you buy a PC or Notebook you should consider "what is it used for?". For example: a officer need a PC for office data processing. I think it will not be efficient if the officer buy PC with high specification such as PC that equipped with Intel Core i7 with 4 GB of VGA card and 8 GB of RAM. Otherwise, a animator need a PC for create animation movie. It also will not good if the animator but PC with low specification such as PC that equipped with Intel Pentium 4 with 256 MB of RAM and 64 MB of VGA Card. So for conclusion, before you buy a PC or Notebook you should consider "what is it used for?". Why? Because if you will buy a high specification PC only for office data processing, you will waste your money. Office data processing will not need high memory or processor consumption. Otherwise, If you buy a low specification PC for create animation movie, you will waste your time because to create animation movie need high specification of VGA card, memory and processor. Low specification PC will not able to handle this work.
Second, you should consider "where are you work". Are you work at indoor or outdoor? You need different notebook for different place work. For example: there are two different notebook. First, Apple Macbook. Second, Panasonic Toughbook. These are two different notebook. Apple Macbook designed for office or multimedia use. Otherwise, Panasonic Toughbook also known as rugged notebook. This notebook is suitable to used in harsh environments for example in outdoor such as forest, garden or desert. It suitable for you are working at outdoor such as police/soldier who working at field or scientists who are conducting field research. Panasonic Toughbook designed for outdoor. It has waterproof and it has hard body because it was designed using metal material.
Consider about "Brand". Many brand of PCs or Notebooks around the world such as Apple, Toshiba, Acer, HP, Compaq, Dell, Samsung, Lenovo, etc. Which one do you like? Who the best? I honestly, I can't answer these questions. Why? Because every brand always has good product and bad product. Sometime, the popular brand produce bad products that make the vendor recall the products. So, it up to you which one you will choose. You can also consider the the most famous brand.
