BEEP CODE

Diposting oleh tegar di 05.44

                  Ketika kita menghidupkan komputer, BIOS akan mengontrol komputer dan melakukan
P.O.S.T (Power On Self Test). Setelah POST selesai komputer akan mengeluarkan
suara ‘BEEP’ satu kali beep pendek untuk mengetahui bahwa pengetesan
sukses.

Tapi jika POST dari BIOS mengalami problem, yang dalam kondisi normal akan
menampilkan visual error message di monitor. Jika problem terjadi sebelum
BIOS inisialisasi video card atau video card tidak terdeteksi, maka BIOS akan
mengeluarkan ‘BEEPS’ untuk mengetahui problem tersebut.
Sangatlah penting kita mengetahui arti dari ‘BEEP’ tersebut untuk acuan dalam
memperbaikinya. Ini adalah tabel AMI, Phoenix dan Award BIOS beep codes.
AMI (American Megatrends International) BIOS Beep Codes.
AMI BIOS menggunakan beep yang sama panjang dan berurutan. Error diketahui
dari banyaknya beep. Contohnya 4 beeps mengindikasikan timer gagal.
BEEP CODE
MEANING
POSSIBLE CAUSE
1 Beep (No video) Memory refresh failure Bad memory
2 Beeps Memory parity error Bad memory
3 Beeps Base 64K mem failure Bad memory
4 Beeps Timer not operational Bad motherboard
5 Beeps Processor error Bad processor
6 Beeps 8042 Gate A20 failure Bad CPU or Motherboard
7 Beeps Processor exception Bad processor
8 Beeps Video memory error Bad video card or memory
9 Beeps ROM checksum error Bad BIOS
10 Beeps CMOS checksum error Bad motherboard
11 Beeps Cache memory bad Bad CPU or motherboard
Award BIOS Beep Codes
Award BIOS menggunakan beep dengan durasi yang berbeda. Beep
panjang biasanya berdurasi 2 detik dan beep pendek berdurasi 1 detik.
Selain itu Award BIOS, juga menggunakan frekuensi yang berbeda untuk masalah
kritis, misalnya pada overheating CPU akan berbunyi beep frekuensi
tinggi yang terus menerus pada saat komputer running.
BEEP CODE
MEANING
POSSIBLE CAUSE
1 Long, 2 Short Video adapter failure Bad video adapter
Repeating (Endless loop) Memory error Bad memory or bad connection
1 Long, 3 Short Video adapter failure Bad video adapter or memory
High freq. beeps (while running) CPU is overheating CPU fan failure
Repeating High, Low beeps CPU failure Bad processor
Phoenix BIOS Beep Codes
Phoenix BIOS menggunakan beep code yang pasti untuk indikasi problem.
Di tabel, tanda ‘-’ yang berarti pause diantara beep.
Contohnya : 1 – 1 – 2 adalah BEEP BEEP BEEP BEEP
