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.First of all, press and hold the on/off button of the laptop to listen to the sound of a fan or a hard disk starting, if there is a sound, it can be run.

Dell laptop won't turn on, you can try the following methods to solve it:

1. Generally, it is the problem of the motherboard, such as the instability of the motherboard chip, corrosion or virtual soldering, etc., which may cause this phenomenon, and if the fault point cannot be determined without actual inspection, it is recommended to send it to the computer maintenance point for inspection to eliminate the fault.

2. It may also be that the battery is completely out of power and can't even be turned on. It is recommended to charge the battery for 5 minutes before turning it on.

3. It may be that there is a problem with the BIOS, you can remove the battery and try it from a new installation, or it may be a problem with the graphics card, it may be, desoldering, this can only be repaired professionally.

Power failure. The first is to check whether there is a problem with the power supply and see if the power supply and plug are not plugged in properly. You can use the same model of power supply to try it, after replugging the power supply, see if it can be turned on, if you change someone else's power supply to turn on, that is a problem with the power supply.

If it turns out that there is no problem with the power supply and the laptop still won't turn on, it could be the hardware.

What happens if your Dell laptop won't turn on?

It's been a long time since I plugged in my laptop i5 and it won't turn on.

The first is to check whether there is a problem with the power supply and see if the power supply and plug are not plugged in properly. You can use the same model of power supply to try it, after replugging the power supply, see if it can be turned on, if you change someone else's power supply to turn on, that is a problem with the power supply. If it turns out that there is no problem with the power supply and the laptop still won't turn on, it could be the hardware.

2. System failure (1) The correct configuration needs to be adjusted, press and hold F8 to enter the advanced options item on boot, and select "Latest Correct Configuration". If it can enter the system, it may be caused by viruses, hardware drivers that are incompatible with the system, operating systems, etc. (2) After entering the system, run the virus software to kill the virus.

After the virus detection is completed, it is not normal to restart the computer. It may be caused by the incompatibility of the device driver with the program, delete the graphics card, network card and other drivers, and restart again to continue to have problems, then go to the next step "Reinstall the system". (3) Repair and install or reinstall the system, set "CD-ROM drive as the first boot device" in the BIOS, then insert the system disk, and press the R button to "repair and install".

If the fault persists, just at the beginning of the system, select "One-click GOST to restore the system" or use the system disk to reinstall the system.

I've plugged in the power supply several times, but it just won't turn on.

The laptop battery body is one.

1. If the laptop cannot be turned on for a long time, you can try to pull out the battery, and then use the power adapter to power it, and it can probably be turned on successfully. 2. Then plug in the battery and see if the charging indicator lights up normally. If the charging display is lit, the battery can still be charged.

You need to turn on the battery after it is fully charged. 3. If there is no signal to enter the monitor, you can open the BIOS system by restarting and installing the F12 button, and then reinstall the system to recover.

The battery body is all-in-one, and the battery cannot be unplugged.

Please use the battery or power adapter separately to power the laptop and see if it can turn on normally. If the battery can support the boot, it may be damaged by the power supply, if the battery cannot support the boot, it means that the external power supply or the battery is damaged or loose. It is recommended that you go to the after-sales point for repair.

See if the power is exhausted, if there is electricity, it can't be turned on, and take it to the maintenance point for a professional person to take a look.

1. It may be caused by the loose battery after the laptop has undergone large fluctuations, you can remove the battery and install it correctly.

2. If the problem of the battery itself is ruled out, it may also be caused by the damage of the conductor at the contact position between the motherboard and the positive and negative electrodes of the battery, and you can find the relevant department for maintenance.

3. If the battery itself is not conductive, it can only be repaired at this time, and the battery problem is difficult for us to solve after all. You can also find the relevant official after-sales service for processing.

4. When the laptop is turned on, swing the lid of the laptop up and down to see if the battery can be used, if it can be used, it is caused by the loose battery.

5. The battery has not been tested.

First, check the power supply to see if the power cord or battery is connected.

Reboot, if it can't be turned on, you can unplug the battery and power cord, wait for 10 minutes and then turn it on.

After turning on the phone, listen to whether there is a boot sound or fan sound. If there is, it may be a screen problem, and you can connect it to an external screen for testing. If the external screen can be displayed, there is a problem with the screen.

If it's not a screen problem, then see if the screen will be slightly brighter than the black screen after booting, if so, you can try pressing F8 to enter safe mode.

Pros of laptops:

Due to the technical characteristics, the technical content of notebook computers, the difficulty and cost of counterfeiting are very high, so there are generally no fake and shoddy products, and there is no real so-called "copycat machine", so it has the characteristics of stable quality and reliable work.

Due to the existence of the battery, the notebook is equivalent to the installation of a long-delay ** working UPS system compared with the desktop, so it can ensure that the laptop at work will not suddenly shut down and lose data when the mains power supply suddenly fails.

It can work for a long time (a few days or even a week) in a sleep state, and the computer in the sleeping state can be started in an instant and quickly enter the working state, avoiding the unbearable and lengthy startup process. This is something you can't do with desktops.
