Solution 2 for Dell laptop won't turn on:

Generally, it means that the laptop does not respond at all after pressing the power button, that is, the indicator light does not light up after pressing the power button, the fan does not rotate, and the laptop does not respond at all. The most common occurrence in this situation is that the laptop battery is dead, or the external AC power supply is damaged or poorly connected.

Check if it's a power supply issue.

First of all, see if the power supply is not plugged in properly or there is a problem with the plug, if you are using a battery, then plug it in and try again. You can go to a friend or find a power supply of the same model to try it. If it can be turned on, then it means that the external power supply is damaged, if not, then it means that there may be a hardware failure inside the laptop or the laptop boot button is out of order, in this case, it is recommended to take it for maintenance.

Check for loose critical components.

If the computer crashes after moving, it may be that the computer has been subjected to a lot of vibration during the move, causing the internal parts of the computer to be loose and in poor contact, resulting in a crash. Open the machine and re-fasten the memory, graphics card, hard disk and other equipment.

Motherboard failure: 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, damage, and damage to the components of the motherboard itself.

Circuit failure: 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 EC peripheral circuits, and sometimes the circuit is burned out in a large area. 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.

There are six reasons why it cannot be turned on: 1. The computer power circuit is faulty, if it is a laptop computer, the battery is dead or damaged, and it cannot be turned on without connecting to the external power supply; 2. The computer boot button is damaged and cannot be turned on; 3. The computer CPU or circuit board is damaged and cannot be turned on; 4. The computer hard disk is damaged and cannot be turned on; 5. The computer memory is damaged and cannot be turned on; 6. The computer system is damaged and cannot be turned on.

If the laptop cannot be turned on after continuous charging, please debug it according to the following scheme:

1. Release static electricity.

1. If the notebook only has an "external" battery, the operation method is: after the main power is turned off, unplug all the connecting cables and connected devices on the body, remove the external battery, press and hold the power button for 10 seconds, press and hold 3 times, replace the battery after the operation is completed, connect the power adapter and start the computer again.

2. If the notebook uses a "built-in" or "built-in + external" battery, you can find out whether the back of the notebook is a small hole the size of a circular needle's eye, and the word "reset" is written near the hole, you can unplug all the connecting wires and connected devices of the fuselage in the power-off state (there is an external battery that needs to be taken out of the external battery), poke the button in the "reset" hole with a paper clip or card needle, for 15 seconds, and check whether the host has been started after 15 seconds, if not, You need to connect the power adapter (if there is an external battery, the external battery will be connected first, and then the power adapter will be connected), and then the power adapter will be turned on after being connected.

2. Replace the same model power adapter for testing.

3. Try to replace the external battery of the same model for testing.

1. If the machine is fully charged, and the battery cannot be turned on after unplugging the power adapter, it may be that the battery is not charged, and the external battery is replaced.

4. If it still can't be turned on after the above operations, or if it is confirmed that the power adapter or battery hardware is faulty after the replacement test, it is recommended that you consider repairing.

5. If you still can't succeed according to the above methods, you can click on the avatar to enter the "Lenovo Business Service" homepage and consult an engineer online to solve the problem.

My dell engineer, the issue is solved as follows:

1.Unplug the battery and power supply, and press and hold the power button for 20 seconds when the computer is not carrying any power and any external devices, which is a discharge of static electricity to the motherboard.

2.If you connect the power adapter separately, that is, the Paivolt charger, turn on the machine, and it can be turned on normally, it means that there is a problem with the battery; If it can't be turned on normally, the three indicators on the keyboard will be lit a few times.

3。Connect the battery separately to turn it on, see how the situation is, if it can be turned on, it is a problem with the charger, if it can't be turned on, it is the same situation with a few clicks of the three indicators.

4.If possible, re-insert the memory and carry it, if it is still the same, exchange the memory for testing if possible.

5.If the problem is still the same after the operation of the fourth step, then consider the motherboard or memory question.

Dell laptops generally fail to turn on for the following reasons:

1.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, repeat the power supply for 6-8 times, 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.Faulty display or graphics card. Solution: It is recommended to send the local service station for testing hardware.

3.The system is compromised. Solution: If you are using a pre-installed genuine win7 system, you can restore the backup data in the logo interface by pressing alt+f10; If you are not using a pre-installed system, it is recommended to back up your data and reinstall the system.

4.Failure of other hardware such as hard disks. Solution: It is recommended to send it to the local service station to test the hardware mountain bucket.

It may be that your memory is insufficient, forcing the operating system to frequently read and write data from the virtual memory of the hard disk from the page swap area of the hard disk, and the hard disk will keep rotating and have IO read and write operations.

Three years of free maintenance upstairs is too much, and the general warranty of Dell is only one year, and if it is three years, it will be necessary to add money to extend the warranty period.

See if you can get into the BIOS, if you can't, it's a problem with the BIOS chip, take off the BIOS battery, wait for half a minute, and then put on the skin, see if you can enter the BIOS, and if you can't, send it to a computer repair shop to change the BIOS chip. If you can enter the BIOS, set it up, change it to a CD boot, fix it with a system CD, if it doesn't work, set it to a USB flash drive, and use a boot USB flash drive to start the computer and fix it. If you can't enter the system without accompanying the hard disk after repair, then reinstall the system.

If you can't reinstall it, you can change the hard drive.

Make sure there are no floppy disks, optical discs, or USB flash drives on the notebook, and then try again. If there is a short English comic prompt, that is, there are English letters, it is a hard disk or memory problem; If there is nothing, most of them are faulty with the motherboard.

But don't panic, go to the repair station for free repairs. At least three years.

This is a hardware problem, if the warranty goes directly to the manufacturer's after-sales free maintenance. The power battery is unplugged and then plugged into the training machine to try it, and it is generally a problem with the motherboard. Notebook hardware is quickly related to the solution to help.

Unplug the memory and erase it with an eraser. If that doesn't work, try it with another memory.

It's a memory problem.

Power supply problem 40% (change the power supply, you also know early - no one has someone to fix the power supply).

Motherboard problem 50% (change motherboard -

10%..Basically, you can rule out the problem of paw jumpers.

The self-test of the hard disk fails.

The self-test of the hard disk fails. Repair!

There are three common reasons for the white screen when booting up, first, the screen cable is damaged or the contact is not good, the second is that the screen itself is damaged, and third, the motherboard has a problem supplying power to the screen or the graphics card chip is caused by virtual soldering, it is recommended that you send it for repair and testing.

In Beijing, I'll help you Shanchun.

If you are not in Beijing, it is recommended that you find a reputable and skilled maintenance company to help you overhaul.

First, press F10 to save the exit and see if you can enter the system. If you still can't get in, it's basically a hardware problem. There is no other way but to go for inspection and repair. Of course, you can take a look at the following options:

Here's how to fix your Dell laptop won't turn on:

First, check that the laptop's power supply is in good contact, as it is possible that the plug is not securely inserted into the socket and can also cause bad contact.

2.The first step is to confirm that it is correct and still cannot be started, check whether there is dirt on the interface of the battery and the plug of the power cord, if this is the reason, you need to do some cleaning work, which may be caused by dirt blockage.

3.Considering that it may be a problem with the power supply, use the battery of the notebook and the external power cord to supply the power respectively, and make a judgment to see whether it is a problem with the battery or the external power supply, and then replace it accordingly.

4.If it still doesn't turn on, go to a computer repair center to check it out and see what the cause is.

Dell computer can't turn on, the computer can't turn on normally, how to solve the problem.

You mean it can be turned on, but it can't work, but what do you mean by not being able to work?!

If it is a boot test, it is recommended that you review the relevant boot detection items after entering the system! For example, if you want to test a disk at boot, you can use it to detect the hard disk and defragment it if necessary!

If the computer is broken, you can fix it.

If there is a loud noise, it may be that the capacitor of the power supply has burst or the computer of the motherboard has burst.

1. First of all, we conduct a comprehensive check on the connection between the computer monitor and the host, and plug each connection back to see if there is a connection problem.

2. If the fault still exists, then we need to open the chassis to see if the chassis contains metals and other substances, causing a short circuit in the computer host circuit, and then we smell the computer to see if there is a burning smell, and see if there are damaged components around the motherboard and around the CPU.

3. After checking the whole chassis, there is no abnormality in the chassis, then we will dust the chassis.

4. If it can't be turned on, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

5. If the fault still exists, it is likely to be the fault of the memory card, graphics card, CPU, motherboard, etc., at this time, we only need to plug and unplug these hardware, or replace it again, and try to find the cause one by one.

6. If the memory, graphics card, CPU and other devices are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, connect the memory, graphics card, CPU, etc. for testing, if the computer can be displayed, then install the motherboard into the chassis for testing until the cause of the fault is found. If the fault persists, you need to return the motherboard to the manufacturer for repair.

7. When the computer is turned on and started, the system BIOS starts to POST (power-on self-test), and when a fatal error is detected in a device in the computer, it will control the speaker to send out a sound to report the error. Therefore, there may be a fault that the power is turned on without displaying an alarm sound. If the computer is turned on and there is no alarm sound, the fault can be checked according to the meaning of the BIOS alarm sound to check the faulty device to eliminate the fault.
