Cooling fan error (902) HP notebook

"The system BIOS has detected a possible issue with the cooling fan,
The cooling fan is an Important Part of a notebook PC. Operation of a notebook PC for an extended period of time without the cooling fan may result in permanent damage to the notebook PC.
Cooling Fan (902)
Enter - Shutdown "
is the message some time ago made me curious.
Some time ago one of my customers are having problems with Compaq notebooks, when turned on in BIOS there is an error message


"The system BIOS has detected a possible issue with the cooling fan,
The cooling fan is an Important Part of a notebook PC. Operation of a notebook PC for an extended period of time without the cooling fan may result in permanent damage to the notebook PC.
Cooling Fan (902)
Enter - Shutdown "


after the restart but the notebook can live inside the notebook sound very noisy fan, this is very scary for those who lay about computers, as a computer technician I had to think fast and precise, I was looking straight fault location and the damage, because the notebook was only 4 months then I do not dare to deconstruct the consideration of this case will void the official warranty from HP.

I tried looking for other alternatives, I released the Notebook battery, then I set aside some time and I blow with a hard on some notebooks the air vents, and it is very unusual, all returned to normal and the message
"The system BIOS has detected a possible issue with the cooling fan,
The cooling fan is an Important Part of a notebook PC. Operation of a notebook PC for an extended period of time without the cooling fan may result in permanent damage to the notebook PC.
Cooling Fan (902)
Enter - Shutdown "
is not there anymore, fan noise was back to normal, after which I concluded was dirty fan exposed to dust, or hair or other debris that interfere with the circulation udaran & cooling processors, because the processor & motherboard notebook sysytem heat then remove the error message "The system BIOS has detected a possible issue with the cooling fan,
The cooling fan is an Important Part of a notebook PC. Operation of a notebook PC for an extended period of time without the cooling fan may result in permanent damage to the notebook PC.
Cooling Fan (902)

hopefully this can help the reader who uses the HP & Compaq notebook

Error code on the Blue Screen Of Death (BSOD)

For Windows XP users may already have experienced a fatal error in Windows, Computer was suddenly dead and appears a blue screen with writing the code the code is not clear, this is called the Blue Screen Of Death or BSOD

Here I will try to explain the causes and how to solve this BSOD, especially is the intent of the codes that appear on our screens

1. IRQL_NOT_LESS_OR_EQUAL (0X0000000A)
This is a mastermind of pure culprit in the BSOD. Since most of the BSOD, this message most often appears. The error message is caused mostly because there is a mismatch drivers installed on your computer.

List of Causes:
* Problem drivers clash or do not match
* Problems Video Card, this cover is on the overclocked video card exceeds the limit or you just changed video card and you do not uninstall the old video card drivers from different chipset
* Issues Audio Card, include configuration errors or bugs in the sound card driver

2. NTFS_FILE_SYSTEM Information or FAT_FILE_SYSTEM (0X00000024) or (0X00000023)
Well, this message at least have a little "disconnected" giving a picture of where the damage was, which is on the partition or housing a filesystem, but not in HD. We can check by examining the SATA or PATA cable or can check the partition with chkdsk tool.

3. UNEXPECTED_KERNEL_MODE_TRAP (0x0000007F)
When you get a message like this, can be caused by:
* Hardware Overclock excessive
* Computer component overheating
* BIOS corrupt
* Memory and CPU is disabled

4. DATA_BUS_ERROR
This message is caused because of the possibility that memory or the memory slot on the motherboard is damaged.

5. PAGE_FAULT_IN_NONPAGED_AREA
Due to hardware damage, including main memory, video card memory, or memory in the processor (L2 Cache)

6. INACCESSIBLE_BOOT_DEVICE
Due to a mistake in the wrong hard drive jumper configuration, boot sector viruses, the wrong IDE controller drivers, or chipset driver error.

7. VIDEO_DRIVER_INIT_FAILURE
An error occurred on the installation of video card drivers are less than perfect, restart during installation or can also occur because of errors in the installation of the driver.

8. BAD_POOL_CALLER
This error can occur because of errors or incompatible drivers. Often occurs during installation of XP from an upgrade, or not from the new installation.

9. PEN_LIST_CORRUPT
This message is caused due to a damaged RAM

10. MACHINE_CHECK_EXCEPTION
Disability caused by the CPU, or an aggressively overclocked, and power supply shortages or damaged resources.

So hopefully useful and you can find the location of the damage of your computer

BIOS Beep Code

Beep Code Manual

AMI BIOS Beep Codes
When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected.
Because there are many brands of BIOS, there are no standard beep codes for every BIOS.

AMI Beep Codes
Beep Code Meaning
1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard.
2 beeps Memory parity error. The parity circuit is not working properly.
3 beeps Base 64K RAM failure. There is a problem with the first 64K of system memory.
4 beeps System timer not operational. There is problem with the timer(s) that control functions on the motherboard.
5 beeps Processor failure. The system CPU has failed.
6 beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode.
7 beeps Virtual mode exception error.
