The host buzzer is the basic input and output system of the internal clamp of the motherboard. The hardware monitoring and management program finds that the hardware is faulty and sends an alarm to the user.
1. Usually long and short beeps are used to indicate the failure of different accessories for users' reference;
2. Motherboards of different manufacturers use different BIOS CMOS modules, so the meaning of the sound is also different;
3. For example, the meaning of the common BIOS tweets of the old AWARD company:
AWARD’s BIOS alarm sound: (AWARD has been acquired by Phoenix)
① 1 short: the system starts normally. This is what we can hear every day, and it also shows that there is basically no problem with the machine.
② 2 short: General error, please enter CMOS Setup and reset the incorrect option.
③ 1 long and 1 short: RAM or motherboard error. Try changing the memory, if it still doesn't work, you have to replace the motherboard.
④ 1 long and 2 short: display or display card error.
⑤ 1 long and 3 short: keyboard controller error. Check the main frame.
⑥ 1 long and 9 short: the motherboard Flash RAM or EPROM is wrong, and the BIOS is damaged. Try another block of Flash RAM.
⑦ Constantly beeping (long beeping): The memory bar is not inserted tightly or damaged. Reinsert the memory stick. If it still does not work, only replace the memory.
⑧ keeps ringing: the power supply and the display are not connected with the display card. Check all the plugs.
⑨ Repeated short beep: power supply problem.
⑩ No sound and no display: power supply problem.
4. When the computer fails, a regular beep will be emitted during the self-checking process of the power-on hardware. The faulty parts on the table can be checked and dealt with accordingly, thus avoiding the blindness of the user.
