Hello Friends, hope you are all doing well!

Your laptop turns on for a moment and then shuts down can cause loss to your data which results in corrupt files if your laptop shuts 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:


If your computer boots up and then suddenly shut down after shortly booting up then your computer's battery may be experiencing problems. There may be several reasons which may cause this problem such as your battery may not be holding a charge properly since the battery is old, the battery charger is damaged or the DC Jack on your laptop may not function properly. It's likely that the battery is losing the ability to fully recharge and may need to be replaced or plugged in all of the time if your laptop's battery 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 isn't working properly. You need to repair it by stopping the problem which won't allow the battery to recharge.


Your laptop may be experiencing hardware conflicts which may cause your laptop to shut down prematurely. It's never easy to remove the internal hardware of a laptop, however, it is easy for you to remove any external hard drives, cameras, or USB devices that are connected to your laptop. After booting run 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 device that's causing problems by trying to reinstall the device drivers.


Your computer will shut down if there is excessive heat from a malfunctioning fan, CPU, memory, video card, or hard drive. In order to reduce your laptop's temperature, you can replace the component that's overheating or by replacing a damaged fan. You can use a laptop cooler to reduce the overall temperature of your laptop If the components inside your laptop aren't failing. 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.


After booting software conflicts can often cause your laptop to crash shortly. There are a number of reasons that can cause software conflicts, however, it's common for multiple virus scanners to open at start-up to cause conflicts. If you have a firewall installed then it may deny start-up services of your computer to operate. Remove any unnecessary start-up programs from the Windows System Configuration tool by accessing from the Control Panel.

“On power-up, Laptop shuts down. The laptop flashes green 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 tried to turn the laptop on after pushing on the power button, the fans started spinning and were active for a few seconds and the laptop just turned itself off. Then the video never came on even if I tried to power it on for 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 an 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 to start the laptop normally. After that open up the laptop case, remove the LCD screen assembly, and then reseat the video card. Surprise, if the laptop starts working with an external monitor attached just in case it restarts 3- 4 times, and each time we got the video on the screen. After assembling everything back if the laptop fails to boot again with the same symptoms then the only part remaining to fail is the LCD Screen assembly. We have unplugged the video cable from the system board and the laptop started to fine once again with the external monitor. Now we know that the problem is somewhere inside the display assembly and the video connector on the system board is fine. The next step is to open up the LCD display assembly and check whether all connectors are seated properly. From the connector on the back of the LCD screen, the video cable is halfway. We then plug the video cable back in place and the laptop works perfectly fine.

This is how an improper plugged video cable prevents an entire system from booting.


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