LAPTOP CREATE BEEP SOUND ON START UP.

Lets look at some of the common reasons why such beeps or sound comes from a laptop:-

RAM Error:-

This problem typically arrives when you replace the RAM or RAM goes bad. When you put a new RAM module on the PC, it may fit loose or may not be properly compatible ram because of different memory specifications. If you have added new module, remove the new module and re-start the computer. This way you can identify if this is related to RAM troubles. In case the RAM has gone bad (happens with some old computers), you need to replace the RAM.

Motherboard Problem:

Multiple beeps in a row or a pattern are an indication of some problem related to motherboard related power on self test failure. You should check which BIOS is installed and then look for the error codes of that BIOS with the number of beeps which you hear when you start the computer.

Processor Problem:

Many times, the processor itself may go bad because of over-heating or bad thermal components. In such case, you will hear multiple beeps at startup. For such case, you should take it to a service center or a trained computer technician.

Other Errors:

There can be many other miscellaneous errors like battery failure error, charger voltage error, display error, expansion slot error etc. Refer to the BIOS error code for the BIOS installed on your computer for details. It will help you diagnose and check what is causing the error.
