Hello Friends, I hope you are all doing well!

If your Laptop turns on for a moment and then shuts down, it can cause data loss, resulting in corrupt files if it slaps down soon after it boots up. You don't necessarily have to go through the expense as it will become confusing for you to buy a new laptop. Commonly at fault, in this case, are your Battery Problems, hardware conflicts, overheating, and software conflicts. Before considering expensive repairs or replacements, troubleshoot these areas:

Battery

If your computer boots up and suddenly shuts down after a short boot-up, your computer's battery may be experiencing problems. Several reasons may cause tithable, such as your battery,ry may not be holding a charge properly since the battery is old, the battery charger is damaged, or the DC Jack on your laptop maLaptopfunction does not function that the battery losing the ability to recharge fully and may need to be replaced or plugged in all of the time if your Laptop is more than a few years old. You can replace the charger with a new one from the manufacturer if your charger is damaged. The plug for your charger will keep slipping out if the power connector jack on your Laptop is working correctly. It would help if you repaired it by stopping the problem, which won't allow the battery to recharge.

Hardware

Your Laptop may experience hardware conflicts, which may cause your computer to slow down prematurely. It's never easy to remove the internal hardware of a computer. However, removing any external hard drives, cameras, or USB devices connected to your Laptop is easy. ALaptopooting runs the computer successfully without external devices, and then again, add them one by one at a time to your system to see which device is problematic. Stop using the device or uninstall the machine, causing problems by trying to reinstall the device drivers.

Heat

Your computer will shut down if there is excessive heat from a malfunctioning fan, CPU, memory, video card, or hard drive. To reduce your Laptop's pressure, replace the overheating component or a damaged fan. You can use a laptop cooler to reduce your Laptop's overall temperature. IfLaptopomponents inside your computer are laptopailing. By cleaning it regularly with compressed air to increase airflow and reduce the build-up of dust and dirt, you can also help your Laptop maintain a lower temperature.

Software

After booting, software conflicts can often cause your Laptop to crash quickly. Several reasons can cause software conflicts. However, it's common for multiple virus scanners to open at start-up to cause conflicts. If a firewall is installed, it may deny your computer's start-to services to remove any unnecessary start-up programs from the Windows System Configuration tool by accessing the Control Panel.

"On power-up, Laptop slapdown. The laptop flLaptopgreen lights for several seconds and then powers down when the power button is pushed. When plugged in, the unit will not stay on with the battery.

When plugged into the AC adapter and trying to turn the Laptop by pushing the power button, the fans started spinning and were active for a few seconds, and the computer just lapped itself off. Then the video never came on, even if I tried to power it on a few times with the same result.


Here is how to fix the problem:

Try with this simple stuff: first, remove the battery and then start the Laptop with a laptop AC adapter plugged in, then reseat and swap the memory module, then remove the hard drive, the DVD drive, and the wireless card. If nothing helps, start the Laptop. After that, open the laptop case, remove the LCD screen assembly, and reseat the video card. Surprise, if the computer stLaptoporking with an external monitor attached just in case, it restarts 3- 4 times, we got the video on the screen each time. After assembling everything back, if the laptop boots again with the same symptoms, the only remaining part to fail is the LCD Screen assembly. We have unplugged the video cable from the system board, and the Laptop stLaptopto is again OK with the external monitor. Now we know that the problem is inside the display assembly, and the video connector on the system board is OK. The next step is to open the LCD assembly and check whether all connectors are seated correctly. The video cable is halfway from the connector on the back of the LCD screen. We then plugged the video cable back in, and the Laptop worked perfectly.


An improperly plugged video cable prevents an entire system from booting.

Conclusion

We hope this blog will be helpful for laptop users who have problems with their laptops turning on for a moment and then shutting down. 

Frequently Asked Questions

Test your charger with a voltmeter. If it is an AC charger, set a voltmeter to 25 VAC. Make the contacts and probes touch, and look for a reading. If there is not a reading on the meter, the charger is not any good.

Check the connection for each PSU cable running to the computer hardware component. Look inside the case for the motherboard light. Usually flashing lights on a motherboard indicate a faulty or misconnected power supply.

A faulty, failing, or malfunctioning circuit or component (e.g., capacitor) can cause the computer to shut off immediately or not turn on at all. If none of the recommendations above help resolve the issue, we suggest sending the computer to a repair shop or replacing the motherboard.

Test your power supply. Just because your computer came on for a few moments doesn't mean that the power supply unit in your computer is working correctly. The power supply tends to cause more problems than any other piece of hardware and is very often the cause of a computer turning off by itself.

You computer's battery may be experiencing problems if your computer boots up but shuts down shortly after booting up. The battery may not be holding a charge properly because the battery is old, the battery charger may be damaged or the DC jack on your laptop may not function properly.

Impossible to say for certain, but most likely it's either the battery or the mains adapter. Laptops will normally work just fine off mains power alone, but a dead battery (I mean truly dead, not just worn out) could stop it working. Take the battery out and try running it just on the mains adapter.
