Dear Lenovo users, hello!
According to the description, it may be caused by poor contact caused by a loose graphics card. It is recommended that you send the machine to the nearest Lenovo after-sales service outlet, and a professional engineer will solve the problem for you.

There is an alarm sound when the motherboard is turned on, indicating that there is a problem with the self-test. The alarm sound is set by the BIOS on the motherboard. There are two types of BIOS, which are AMI and Award. Most motherboards are AWARD BIOS.
1) The BIOS of the award is set to:
A long and constant sound: the memory module is not plugged in tightly.
One short: the system starts normally.
Two shorts: The CMOS settings are incorrect and need to be set again.
One long and one short: Memory or motherboard error.
One long and two short: The monitor or graphics card is wrong.
One long and three short: The keyboard controller is wrong.
One long and nine short: Flash RAM or EPROM error of the motherboard BIOS.
2) The BIOS of the AMI is set to:
1. Short: Memory refresh failure.
Two shorts: The memory ECC verification error is incorrect.
3. Short: The basic memory check of the system fails.
Four short: The system clock is wrong.
Five short: There is an error in the CPU.
Six short: The keyboard controller is wrong.
Seven short: The real mode of the system is wrong.
Eight short: Displays a memory error.
Nine short: BIOS chip inspection error.
One long and three short: memory error.
One long and eight short: the monitor data cable or graphics card is not plugged in.
