When it starts up, a computer emits one or more beeps. The laptop is trying to communicate with you. Here are the explanations of the man (beep) who whispered in the ear of the motherboard as Dell service center Mumbai explained.

When you start a PC, it beeps. We do not necessarily realize it, but by this simple beep, Laptop means that all is well. The laptop is happy. Only sometimes, it emits different beeps, several, long, short ... All that to refuse to start. The laptop tells you that there is a problem, and even where it is. Except that it's a bit like walrus, you have to know the code.

For your information, it is the BIOS, contained in the memory integrated into the motherboard that speaks to you like this. According to Dell service center Delhi, every time you turn on your PC, it quickly looks at the status of the machine's main vital functions before reporting to you. So 1 beep: everything is fine.

  • battery

- 2 short beeps: there is a CMOS problem. Certainly, said like that, it may sound barbaric. To put it simply, the CMOS is a memory that stores the very first element which will start the OS. So 2 beeps, there is confusion in this memory, and it must be emptied to refurbish it, with the factory settings. To do this, you must remove the battery from the motherboard then put it back, or move the CMOS Jumper (see the motherboard manual for its location).  

-1 long beep then 1 short beep or incessant long beeps  : means a RAM problem. Check that your RAM modules are properly seated. If so, remove them one by one to find the one that no longer works.

-1 long beep then 2 short beeps:  This is the graphics card. It is misplaced, or dead...

-1 long beep then 3 short beeps: you forgot to connect a keyboard! Or yours has a problem...

-1 long beep then 9 short beeps: The BIOS is bad, it must be replaced (flash). A complex and delicate operation, but also dangerous, that we advise you not to take lightly. 

- 3 long beeps: Another RAM problem, more precisely in the first 64 KB. This does not change much: you have to check that they are properly plugged in or identify which strip is dead. 

- 4 long beeps: RAM is poorly refreshed. To reset the initial values, empty the BIOS memory (CF: 2 short beeps: the Clear CMOS)

- 5 long beeps: Oulala is the processor! Check that it is plugged in and that its fan is working, otherwise it will have to be changed... 

-6 long beeps: same as 1 long beep / 3 short beeps 

- Constant short beeps:  The Bios tells you that there is not enough energy to function. Check the power cables to the motherboard, if not, you need a new block...

This little BIOS lexicon is valid for the overwhelming majority of recent BIOSes (AWARD), which all speak the same language as Dell service center Pune suggested. With some nuances of dialects. This is why some codes mean the same thing.
