Understanding Meaning in BIOS Beep Codes

As we have seen that the primary function of the BIOS is to POST, now when the BIOS detects a problem with one of the hardware components are checked, then the BIOS will emit known as BEEP. On the BIOS beep and means we can use to simplify troubleshooting a computer malfunction.

1 x Short Beep

1 short beep beep times is that we often hear at the first time the computer is turned on and is this normal conditions, short beeps 1 time indicating no problems with the hardware that is checked by the BIOS.

1 x Long Beep, Beep 2 x Short

One long beep followed by two short beeps indicates that there has been some kind of error with the video card. Replace the video card is usually the most you have to do to fix this one.

1 x Long Beep, Beep 3 x Short

One long beep followed by three short beeps means that either the video card is not installed or the memory on the video card is bad. Try to replace the video card (VGA Card) to fix it. \

1 x high-pitched beeps, 1 x low-pitched sound (Repeat)

A high-pitched beep followed by a low-pitched beep is an indication of a problem with the CPU (Processor). Usually occurs overheating (overheating) on ​​Processor Processor or damage due to other causes.

1 x  high pitched beep (Recurring)

A high-pitched beep code indicating the condition repeated Processor is overheating. Immediately turn off the computer at the time aware of any overheating of the processor's because overheating condition may damage the processor.

1 x Other Beep

This causes the heat that would otherwise be issued re-entry into the laptop. As a result, the temperature inside the laptop up from the seharusanya allowed. This can cause over heating on chip VGA, Processor, and other components of the laptop mainboard.

Problems Port and Power Connectors
This problem also occurs frequently. This is caused by the breakdown of the existing solder on the connectors or ports. Solder cracking caused by heat and the age of the laptop itself. The solution is to re-solder the parts that have cracks solder.

Good work!
