What should I do if my Acer computer is experiencing symptoms that won t turn on?

First, check whether the host fan will be fanned.

Acer computer has symptoms that cannot be turned on, first check the power supply, memory, if it still can't start, then you need to go to the after-sales test.

1. Common reasons why the laptop cannot be turned on.

1. Power supply problems.

If it is an external power supply, first see if the power supply is not plugged in properly or there is a problem with the plug. If you are using a battery, it may be that the laptop power supply is running low.

2. The motherboard is faulty.

Motherboard failure is the main reason why laptops won't turn on. It is often caused by factors such as liquid ingress of the notebook, breakage, and damage to the components of the motherboard itself.

3. Circuit failure.

In addition to artificial liquid ingress and short circuits, most of the failures of laptops that cannot be turned on are problems with the protection isolation circuit, the failure of the boot circuit and the EC peripheral circuit, and sometimes the circuit will be burned out in a large area.

4. BGA failure.

BGA failure is also a failure caused by the laptop not being able to turn on, which is extremely common in notebooks that use DBM as the South Bridge chip in the Swift Relaxation generation.

5. If it cannot be solved, it is recommended to send it to the after-sales center for maintenance.

1.Can I turn on when powered by battery alone? (Yes=2, No=4).

2.Can I see the Acer BIOS screen? (Yes=3, No=a).

3.Can I load the operating system? (yes=b, no=a).

4.Is the LED indicator of the power adapter on? (yes=5, no=c).

5.Can I turn on the power adapter when it is used alone? (Yes=6, No=a).

6.Can I see the Acer BIOS screen? (yes=7, no=a).

7.Can I load the operating system? (Yes=d, No=a).

A: The problem may be due to the failure of the motherboard, hard disk and laptop, please send the laptop to your local service center for testing.

B: The problem is caused by the abnormality of the operating system, please reinstall the operating system, if the original factory pre-installed system, you can try one-click restore for system recovery.

C: The power adapter is faulty, please check whether the cable of the power supply is normal, otherwise please go to the local service center to replace the adapter.

D: Battery problem, please check whether the battery is fully inserted into the battery slot, otherwise please send the laptop and battery to your local service center for testing.

1. Check whether all the plugs of the power supply and the wires on the adapter of the notebook are firmly inserted into their respective sockets, if not, it means that the contact with the power supply is poor, just press the plug down again.

2. If the indicator light is not yet on, on the premise of ruling out the power adapter, it must be that there is a problem with the power chip of the motherboard or a short-circuit breakpoint, and the motherboard is not powered on.

3. If the indicator light responds but the screen is black, it may be a problem with the graphics card or memory.

4. There is no display when the boot is normal, check whether the power cable, switch, and data cable of the display are correct, and it is also possible that the display is damaged.

1.Check whether there is a physical fault with the power and restart buttons, the most common is that you can't get up when you press it, and this problem occurs in either of the two buttons, which can cause the computer to fail to boot normally. The workaround can only be sent for repair or replacement of the chassis, because the chassis is integrated in.

2.Open the case, unplug the motherboard BIOS, wait for a while, and then press it again to see if the computer can run normally.

3.Unplug all the cables connecting the motherboard from the chassis and use a screwdriver.

Touch the motherboard power control pin (Since there are many pins, confirm the power control pin.)

4.Unplug the power supply from the data and power cords between the motherboard, optical drive, hard disk, floppy drive, and other devices, and remove all devices on the backplane of the motherboard.

How can I solve the situation that Acer notebook does not respond when it boots up? Replace the power adapter.

There are many reasons why the notebook cannot be turned on, including the corresponding fault phenomenon, and we can judge different fault causes according to different fault phenomena, so as to find the corresponding solution.

1.Phenomenon: The power light does not light up after pressing the power on/off button, but the charging indicator light is on.

Reason: The motherboard is not powered on.

Solution: Try to release static electricity (remove the battery and power cord of the computer, make sure the laptop is in a completely unpowered state, press the power switch 6-8 times repeatedly, continue to press and hold for 6-8 seconds each time, connect the power supply and try to turn it on), if it can be normal.

Boot up, fault solving; If it still can't be turned on normally, it is recommended to send it to the local service station for testing hardware.

2.Phenomenon: After pressing the power on/off button, the power light turns on, and you can hear the sound of hardware running, but there is no display on the screen.

Cause: Faulty display or graphics card.

Solution: It is recommended to send the local service station for testing hardware.

3.Phenomenon: After pressing the power on/off button, you can see the ACER logo interface, and then you can't enter the system, and the repair meter is prompted on the screen.

If an error message is reported on the computer or in English, press F2 on the ACER logo interface to enter the BIOS setting interface.

Cause: The system was compromised.

Solution: If you are using a pre-installed genuine Win7 system, it is recommended to restore the backup data in the ACER logo interface by pressing Alt+F10 with one click; If you are not using a pre-installed system, it is recommended to back up your data and reinstall the system.

4.Phenomenon: After pressing the power on/off button, you can see the ACER logo interface, and then you can't enter the system, and the screen prompts an English newspaper.

Error message, pressing F2 on the ACER logo interface cannot enter the BIOS settings interface.

Cause: Failure of other hardware such as hard disks.

Solution: It is recommended to send the local service station for testing hardware.

Check the power supply to see if it is done, plug it in and press the power button to turn it on.
