Lenovo Y450 notebook boot has an alarm sound

Alarm sound: (1): A short one, indicating that there is no problem with the computer.

2): Two short, general error, please go to BIOS settings, from the new set incorrect option. （3）：

One long and one short, the RAM or motherboard is wrong. Try a different memory module, if it still doesn't work, you can only replace the motherboard. （4）：

One long and two short, the monitor or graphics card is wrong. (5): One long and three short, keyboard controller error, check the motherboard.

6): One long 9 short, RAM or EPROM error, BIOS corruption, change block flashram try. （7）：

Constant ringing (long sound), the memory module is not plugged in tightly or damaged, reinsert the memory module, if it still does not work, only replace the memory module. (8): Keep ringing, the power supply, the monitor is not connected to the graphics card properly, check all the plugs.

9): Repeated ringing, power supply problem. （10）：

No sound, no display - there is a problem with the power supply, the BIOS of AMI company is different from the BIOS of Award company, and its alarm sound and meaning are as follows: (1): One short, memory refresh failed, replace the memory module.

2): Second, the memory ECC verification error, in the BIOS settings, the memory about ECC verification option can be set to disabled, but the most fundamental solution is to replace a memory. （3）：

3 Short, system base memory (first 64kb) check failed. Swap memory (4): 4 is short, the system clock is wrong.

5): 5 is short, CPU error. （6）：

6 short, keyboard controller error. (7): 7 is short, the system real mode is wrong, and it cannot be switched to protection mode.

8): 8 short, display memory error, display memory problem, replace graphics card try (9): 9 short, rombios check error (10):

One long and three short, the display test is wrong, the monitor cable is not plugged in or the graphics card is not plugged in, and the decision can be made according to the different prompt tones.

It is recommended that it is best to repair it in the store and not to disassemble it yourself.

Divided into. Here are a few steps1Pick up Notebook 2Aim at the ground at a 45-degree angleSmash! 4.Power on5Boot up normally.

Could it be that there is a problem with the graphics card and the alarm is called? Or maybe there's something wrong with the system.

1. 1 short sound - the system starts normally.

2. 2 Short Tone - General Error. The CMOS reset error option should be entered.

3. 1 long and 1 short sound - RAM or motherboard error.

4. 1 long and 2 short sound - the monitor or graphics card is wrong.

5. 1 long and 3 short - The keyboard controller is wrong.

6. 1 long and 9 short sounds - motherboard flashram or eprom error.

7. Uninterrupted long sound - the memory is not plugged in or the chip is damaged.

8. Non-stop ringing - the monitor is not properly connected to the graphics card.

9. Repeating a short sound - power failure.

10. No sound and no display - no power, or the CMOS battery is drained, or the CPU is wrong.

1. If the sound keeps ringing, it may be that the memory module is not plugged in tightly2. If the sound is fast and short and rings twice (such as drip, drip): it may be that the CMOS setting is wrong and needs to be reset, this situation occurs the most, and the bottom of the screen (generally in the bottom left) will appear in English prompt "CMOS checksum failure", and then ask to press F? （f？

It could be F1 F12, depending on the motherboard) to load the default settings or enter. In addition, this problem may also occur after flashing and updating the BIOS, just load the default settings.

3. If the sound is one long and one short, it may be a memory or motherboard error.

4. If the sound is one long sound and two short sounds, it may be an error in the monitor or graphics card.

5. If the sound is one long sound and three short sounds, it may be the keyboard controller error.

6. If the sound is one long sound and nine short sounds, it may be the flash RAM or EPROM error of the motherboard BIOS.

1. If the sound is only a short sound, it may be a memory refresh failure.

2. If the sound is fast and short twice, it may be a memory ECC verification error.

3. If the sound is fast and short twice, it may be that the basic memory check of the system has failed.

4. If the sound is fast and short four times, it may be that the system clock is wrong.

5. If the sound is fast and short five times, it may be that the CPU has an error.

6. If the sound is fast and short six times, it may be a keyboard controller error.

7. If the sound is fast and short seven times, it may be the real mode error of the system.

8. If the sound is fast and short eight times, it may be a memory error.

9. If the sound is fast and short nine times, it may be a BIOS chip inspection error.

10. If the sound is one long sound and three short sounds, it may be a memory error.

Summary. 1.There is a problem with the motherboard capacitor, which usually occurs on older machines.

Solution: Replace the motherboard or take it for repair. 2.

Power supply problems, insufficient power supply, or aging power supply, voltage instability, for the problem that the power supply of the computer is turned on and turned off, this situation occurs the most, there are new machines, and there are old machines. If more is recommended if it appears. 3.

If this situation occurs in summer, it is necessary to consider whether the external voltage is unstable or too low, because of the shortage of electricity in summer, the voltage of civil electricity in many places will be reduced, resulting in the computer can not be turned on. If this happens, try adding a regulator or transformer. 4. The motherboard battery is out of power, and a small number of computers will not be able to turn on the computer normally because the motherboard battery is out of power

Replace the motherboard battery.

Mine is a Lenovo Y450 laptop. When it is turned on. The indicator light turns off as soon as it comes on. It doesn't turn on.

1.There is a problem with the motherboard capacitor, which usually occurs on older machines. Workaround:

Replace the motherboard or take it for repair. 2.Power supply problems, insufficient power supply, or aging power supply, voltage instability, for the problem that the power supply of the computer is turned on and turned off, this situation occurs the most, there are new machines, and there are old machines.

Fellow, I really didn't understand, I can be more specific.
