Beep Code Pada BIOS

Power-on self-test (POST) adalah suatu proses sebuah komputer, router atau printer sebelum melakukan booting, POST ini dikendalikan oleh BIOS. Disaat kondisi seperti ini biasanya perangkat melakukan pengujian terhadap sistemnya dan akan menghasilkan laporan berupa video atau audio. Berupa video sering ditampilkan berbentuk indikator led ataupun ditampilkan pada monitor. Sedang berupa audio itu sering disebut dengan suara beep. Berikut ini analisa dan deskripsi perbaikan motherboard dengan Beberapa BIOS.

LANGKAH PERBAIKAN RINGAN
Suara Beep
Cara Perbaikan
1 dan 3
RAM rusak atau tidak terpasang dengan benar. Lepaskan dan pasang kembali. Pastikan bahwa RAM yang anda pasang tidak rusak.
6
Biasanya menunjukkan keyboard yang rusak, atau tidak terpasang dengan benar.
6 dan 7
Jika beep terjadi ketika semua Expansion Cards telah dilepas/disable sebaiknya konsultasi sama Vendor motherboard anda. Jika beep tidak terdengar ketika Expansion Cards dilepas coba enable/pasang expansion cards satu persatu.
8
Card / VGA rusak atau tidak terpasang dengan benar. Jika VGA anda add-in (onboard) coba disable bios dan pasang VGA Adapter yang baru.

DAFTAR BEEPS CODE Phoenix-BIOS
Phoenix menggunakan urutan berbunyi untuk menunjukkan masalah. Antara setiap angka di bawah menunjukkan jeda antara setiap urutan berbunyi. Sebagai contoh, 1-2-3 menunjukkan satu bip, diikuti dengan jeda dan dua bip, diikuti dengan jeda dan tiga beep. Phoenix versi sebelum 4.x menggunakan 3-bip kode, sedangkan Phoenix versi 4.x dimulai dengan menggunakan 4-bip kode.
