What can you check for the problem based on the following points? Hope it helps! Have fun! 

The first step is to analyze according to the specific situation, if the power supply is not responding, we first need to check whether the power supply, poor contact, hardware and other problems, if yes, then the second step, if it is not able to enter the system may be an operating system or software problem to go to the third step.

Step 2. If you're sure it's a power issue, check that the wires are plugged in properly and that the plug is loose, and if you're using a battery, plug it in and try again. You can find a friend or go to a computer repair shop or sales store to find the same model of power supply to try. After repeating the operation, press the power button again.

If you still can't open, press it for a while. If someone else's power can be turned on, then there is a problem with the power supply**. If there is no problem with the power supply, it may be a hardware cause, go to step five.

Step 3. First, start the machine and press and hold F8. Then go to the options page and select "Last Correct Configuration" to enter. If you can get into the system, it is very likely to be infected with viruses or hardware drivers that are not compatible with the system, operating system, etc.

Once in the system, run antivirus software, kill the virus, and if there is a virus, restart the computer after the virus. If you have questions, go to the next step.

Step 4To install or reinstall the system, please set the "Optical Drive as Boot Device" in the BIOS, insert the system disk, and press the R button "Repair Follow". If the fault persists, just enter the system to start, select "One-click GOST to restore the system" or reinstall the system using the system disk.

The fifth step is the problem of hardware, first of all, what we need to do is to disassemble the computer, and then check whether the hardware is loose. If there is too much dust inside the laptop, clean it up first. Also, we should pay attention to whether it is due to new and replaced hardware.

If the hardware is normal before the replacement, but not after the replacement, check whether it is compatible. If it still doesn't start, send it in for repair and a professional will check your hardware one by one to see if there's a problem.

2.Check whether the hard disk is loose, and operate it after power-off and shutdown.

3.If the hard drive is loose, disassemble the computer and replace the hard drive.

4.If there is a ticking sound after turning on the computer, disassemble the computer and replace it with a memory module.

If the hardware is loose, just open the notebook and reinsert the loose hardwareHowever, due to hardware damage, the damaged hardware should be replaced after testing with a professional instrument.

6. When the machine is turned on, it prompts that the serial port, parallel port, hard disk, etc. cannot be recognized. This type of situation is usually caused by loose hardware or the same error of COMS data, and can only be troubled by reinserting the loose hardware and restoring COMS data.

Hello, it is recommended to clean the computer thoroughly and replace the motherboard battery.

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.

Second, the Dell laptop can't be turned 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.
