CODICI DI ERRORE (BEEP) DEI BIOS


Quando ci sono problemi alla partenza di un PC il BIOS emette dei codici sonori (Beep) che sono associati ad un determinato errore.

Questa guida contiene i relativi codici di errore associati ai Beep emessi dal PC per i principali BIOS (AMI,AWARD,PHOENIX,IBM) e la relativa soluzione.
 

 
BIOS "AMI"

N Beep Descrizione dell'errore Possibile soluzione
1 Beep Memory refresh timer error - Togli e rimetti i moduli di RAM
- Provane uno alla volta
- Sostituisci la RAM difettosa
2 Beeps Parity error in base memory (first 64KB block) - Togli e rimetti i moduli di RAM
- Provane uno alla volta
- Sostituisci la RAM difettosa
3 Beeps - Base memory read/write test error - Togli e rimetti i moduli di RAM
- Provane uno alla volta
- Sostituisci la RAM difettosa
4 Beeps Motherboard timer not operational  
5 Beeps Processor error  
6 Beeps 8042 Gate A20 test error (cannot switch to protected mode)  
7 Beeps General exception error (processor exception interrupt error)  
8 Beeps Display memory error (system video adapter)  
9 Beeps AMIBIOS ROM checksum error  
10 Beeps CMOS shutdown register read/write error  
11 Beeps Cache memory test failed  
1 Lungo + 3 Brevi Beeps You've probably just added memory to the motherboard since this is a conventional or extended memory failure. Generally this is caused by a memory chip that is not seated properly. - Togli e rimetti i moduli di RAM
1 Lungo + 8 Brevi Beeps Display / retrace test failed.  - Togli e rimetti la scheda Video

 
BIOS "AWARD"

N Beep Descrizione dell'errore Possibile soluzione
1 Beep Lungo, 2 Beeps brevi Video adapter error - Togli e rimetti la scheda video.
- Sostituisci la scheda video.
- Se la scheda video integrata, prova ad aggiungerne una PCI o AGP esterna.
1 Beep Lungo, 3 Beeps brevi No video card is present or video RAM is bad - Togli e rimetti la scheda video.
- Sostituisci la scheda video.
- Se la scheda video integrata, prova ad aggiungerne una PCI o AGP esterna.
Beep Alto-Picco/Beep Basso-picco alternati (e ripetuti) Processor error - Togli e rimetti la CPU.
- La CPU danneggiata, sostituirla.
Beep Alto-Picco ripetuti Processor overheating - Surriscaldamento CPU.
- Pulisci o sostituisci la ventola del processore
- Togli e rimetti la CPU.
- La CPU danneggiata, sostituirla.
Tutti gli altri tipi di Beep Memory error - Togli e rimetti i moduli di RAM
- Provane uno alla volta
- Sostituisci la RAM difettosa


 
BIOS "PHOENIX"

N Beep Descrizione dell'errore
1-1-3 Your computer can't read the configuration info stored in the CMOS. Replace the motherboard. 
1-1-4 Your BIOS needs to be replaced. 
1-2-1 You have a bad timer chip on the motherboard. You need a new motherboard. 
1-2-2 The motherboard is bad. 
1-2-3 The motherboard is bad. 
1-3-1 You'll need to replace the motherboard. 
1-3-3 You'll need to replace the motherboard. 
1-3-4  The motherboard is bad. 
1-4-1 The motherboard is bad. 
1-4-2  Some of your memory is bad. 
2-_-_  Any combo of beeps after two means that some of your memory is bad, and unless you want to get real technical, you should probably have the guys in the lab coats test the memory for you. Take it to the shop. 
3-1-_  One of the chips on your motherboard is broken. You'll likely need to get another board. 
3-2-4 One of the chips on your motherboard that checks the keyboard is broken. You'll likely need to get another board. 
3-3-4 Your computer can't find the video card. Is it there? If so, try swapping it with another one and see if it works. 
3-4-_  Your video card isn't working. You'll need to replace it. 
4-2-1 There's a bad chip on the motherboard. You need to buy another board. 
4-2-2 First check the keyboard for problems. If nothing, you have a bad motherboard. 
4-2-3  Same as 4-2-2. 
4-2-4  One of the cards is bad. Try yanking out the cards one by one to isolate the culprit. Replace the bad one. The last possibility is to buy another motherboard. 
4-3-1 Replace the motherboard. 
4-3-2 See 4-3-1
4-3-3 See 4-3-1
4-3-4 Time of day clock failure. Try running the setup program that comes with the computer. Check the date and time. If that doesn't work, replace the battery. If that doesn't work, replace the power supply. You may have to replace the motherboard, but that is rare. 
4-4-1 Your serial ports are acting up. Togli e rimetti, or replace, the I/O card. If the I/O is on the motherboard itself, disable them with a jumper (consult your manual to know which one) and then add an I/O card. 
4-4-2 See 4-4-1, but this time is your Parallel port that's acting up.
4-4-3 You math coprocessor is having problems. Run a test program to double-check it. If it is indeed bad, disable it, or replace it.
Low 1-1-2 Your motherboard is having problems
Low 1-1-3 This is an Extended CMOS RAM problem, check your motherboard battery, and motherboard.
