What to do if your laptop won t turn on

The possible reasons are as follows:

1. If there are two memories of motherboard failure and memory failure, it is recommended to pull out one memory and keep one memory for boot attempt.

2. Graphics card and screen cable failureGeneral graphics card and screen cable failure can usually enter the operating system, if you have set up the boot**, if you can hear the sound of entering the system when you boot up, it means that the graphics card or the screen cable is faulty or loose. For the above hardware failures, it is estimated that the vast majority of users cannot handle it, so it is recommended to send it for repair.

3. Loose hardware, such as loose memory or graphics card, especially the memory has the greatest chance, try to plug it in and unplug it again.

4. If the motherboard BIOS error is caused by the motherboard BIOS error, you need to clear the BIOS, complete the discharge operation, and reset it. The above reasons can only answer for you a general direction of failure, for Xiaobai, even if we encounter hardware failure, we can't repair it ourselves, but we can try whether the hardware is loose and the motherboard clears the BIOS.

Hello friends:

First of all, try the following operations: remove the battery and power adapter, press and hold the switch button for 30 seconds to discharge the static electricity, wait for about 15 minutes, and then connect the power adapter separately to power on; If it can't be turned on yet, it is the following reasons.

1) The first reason is that the power adapter of the notebook is damaged and cannot be powered on, or the battery of the notebook is out of power, and it cannot be turned on from the surface to the black screen. Solution: Replace the power adapter or fully charge the battery.

2) The second reason: is that the memory and graphics card of the notebook are oxidized, resulting in poor contact with the memory slot or graphics card slot, resulting in inability to turn on, black screen, treatment method:

Solution: It is to remove the power supply, open the back cover of the notebook, take out the card slot of the memory, if it is not an independent graphics card soldered to the motherboard, also take out the card slot, align the part of the memory and the gold finger of the graphics card (that is, where there is a copper sheet) and wipe it back and forth with an eraser a few times, blow the ash, and then insert it back, cover the back cover, and it is generally OK to boot up.

3) The third reason: is that the graphics memory of the notebook graphics card is soldered, the performance of the main chip is reduced, the graphics card BIOS is disordered, and the control power supply IC is problematic, which will cause the graphics card to fail to work normally, that is, the graphics card is broken, because the graphics card is broken, it will naturally not be able to boot, and the screen will be black.

4) The fourth reason: the boot circuit of the notebook motherboard is faulty, such as clock, reset, power supply, MOS tube, etc., which may cause failure to boot, black screen, IO problems, unable to start the computer, black screen, etc., Solution: Send after-sales or repair shop to repair the motherboard, I hope it will help you, I wish you happiness

The laptop won't turn on, what's going on, and the solution is as follows

The correct steps to deal with the laptop won't turn on. 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 turned on normally, the fault is solved; If it still can't be turned on normally, it is recommended to send it to the local service station for testing hardware. Motherboard failure:

Motherboard failure is the main reason why laptops won't turn on. If you really can't open it, it is recommended to find a professional to repair the computer.

The reasons why the laptop can't turn on the machine are: low battery, power failure, hardware failure, operating system failure, BIOS setting error, etc.

1. The battery is insufficient

If the battery is low, the laptop may not turn on. You can try charging or replacing the battery.

2. Power supply failure

If the power supply** fails, the laptop won't turn on either. You can check that the power adapter and power cord are working properly, or try replacing the power adapter.

3. Hardware failure

If your laptop's hardware fails, it can also cause it to fail to turn on. You can try to disassemble the laptop to check if the hardware is normal, or take the laptop to a professional repair center for repair.

4. Failure of the car operation and errand system

If your laptop's operating system fails, it can also cause it to fail to turn on. You can try to go into safe mode or use the system recovery feature to repair the operating system.

5. The BIOS setting is incorrect

If the BIOS is set incorrectly, it may also cause it to fail to boot up. You can try resetting the BIOS settings or updating the BIOS version.

Reasons why the laptop can't be turned on: 1. If the power supply is an external power supply, first see whether the power supply is not plugged in well or the plug is problematic. If you use a battery, it may be that the power supply of the laptop is insufficient, as long as you charge it more before use, this problem will be solved.

2. Motherboard failureMotherboard failure is the main reason why the laptop cannot be turned 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. In addition to artificial liquid inlet and short circuit, most of the faults of laptops that cannot be turned on are problems with the protection isolation circuit and the failure of the boot circuit and the EC peripheral circuit, and sometimes the circuit is burned out in a large area.

4. BGA failureBGA failure is also a triggerThe failure of the laptop to turn on is extremely common in the laptops of the Swift Relaxation generation that use DBM as the South Bridge chip.

Here's how to deal with laptop won't open:1.If the power display of the laptop is not connected, then we need to check whether the power supply, poor contact or hardware problems are loose.

2.After the computer is turned on, we press and hold the F8 key to enter the options interface, then select the most recent correct configuration option, and then press the enter key. If you can enter the computer system, then it is likely that the laptop will not turn on due to a virus infection or the hardware driver is not compatible with the system, or the operating system is a problem.

3.Hardware problems cause the laptop to not turn on, first we need to disassemble the laptop, and then check whether the hardware of the computer is loose, if there is too much dust inside the laptop, we will clean up the dust first. However, it is recommended that if there is a problem with the hardware, you can go to the repair shop in time to repair it and avoid repairing the damaged hardware by yourself.
