5 Common Causes For Laptop Not Turning On

If your laptop screen turns off when you plug it in, or it won’t start up, there’s a good chance that your battery is dead. And, if your laptop won’t turn on, your motherboard or power supply is likely faulty.

If your laptop screen turns off intermittently, there’s a chance that your screen break or the connector is loose. In any of these cases, fixing the problem might involve replacing the battery, motherboard, power supply, or screen. If the problem is more complicated, such as a faulty power cord, your laptop may need to send in for repair.

Discharge The Battery

Discharge The Battery

There are a few common reasons why a laptop might not be turning on. One of the most common is when the battery is discharged.

To check whether your battery is in good condition, try turning on the laptop without plugging it in. If it still doesn’t work, your battery may be discharged and need replacement. Before you do this, make sure to back up any important data that you may need first.

The battery may also discharge if you’re using your laptop for an extended period without unplugging it. In this case, you can try charging the battery overnight or using a power adapter.

Faulty Ac Adapter

If your laptop battery is low, the AC adapter might be unable to supply power. To check if this is the case, you can try lugging in and out of the laptop and checking whether multiple lights flash when plugged into a power source.

If these checks fail or are inconclusive, it might be time for a new AC adapter. In some rare cases where the motherboard might be faulty, it will need to replace along with the AC adapter.

The Bad Power Supply Unit

The Bad Power Supply Unit

The most common is a bad power supply unit. An electrical fault usually causes this in the unit and can be difficult to diagnose.

If you’re experiencing problems with your laptop, you should try to power it down using the computer’s power button. And, if that doesn’t work, try connecting it to a different outlet and see if that solves the problem. If neither of those solutions works, you may need to take it to your local repair shop.

If you have a bad power supply unit, it will likely cause other problems, like poor performance or random crashes. In most cases, replacing the power supply unit will fix all these issues.

Damaged Motherboard Or Processor

To fix this, you will need to replace the damaged component. If the laptop starts up but then shuts down shortly after, it may be due to a corrupted file or virus. And, if the laptop turns on but runs slowly or has other issues, it may be because of a defective battery or cooling system. If you are unsure of your laptop’s problem, bring it in for repair.

Dust Accumulation On Electronics

Dust accumulation on electronics can be a major problem. It can cause your laptop to not turn on or affect the battery or motherboard.

To prevent this from happening, clean your laptop regularly and remove any dust particles that may accumulate. Additionally, wipe down the inside of the laptop with a cloth dampened in rubbing alcohol – this will also clean any internal parts and remove any residual dust particles.

Last but not least, make sure metal objects like coins or keys don’t block contact between your battery and motherboard – this could lead to damage.

How To Fix Laptop Not Turning On

How To Fix Laptop Not Turning On

If your laptop isn’t turning on, there are a few things you can do to try and fix the problem. First and foremost, check if the battery is fully charged and if the power goes to the laptop via an AC adapter or USB port.

If that doesn’t work, restart the computer with both batteries installed. If that doesn’t work, try using a clean boot option to clear out any unnecessary programs that may interfere with system startup or performance.

1-Check The Power Supply

  1. Make sure the power supply is plugged in and not overloaded.
  2. Try a different outlet to see if that solves the issue.
  3. If the laptop still doesn’t turn on, it may be time for a new battery or resetting it by pressing and holding down both FN buttons until you see a message on the screen saying, “Laptop has been reset.”

2-Check The Screen

For checking the Laptop screen:

  1. Ensure the lighting is adequate by checking if something is blocking the light from coming in – like a piece of paper or a tissue.
  2. If your laptop screen cracks, you will need to replace it as it will not be safe.
  3. Check that the power cord and plug are fully inserted into the computer and outlet – they can easily get misplaced.
  4. Ensure all cables plug in properly – they can easily lose.

3-Unplug And Removable USD Drives Or Memory Cards

When your laptop is not turning on, a faulty battery is the most common reason. So, remove any removable USB drives or memory cards and firmly plug in the power cord to check if this is the case. If everything fails to turn your computer back on, it might be time for an authorized technician’s visit.

4-Try A Rescue Disc

Sometimes problems with our laptops can become bigger headaches if not fixed quickly. In such cases, the first step is always to try a rescue disc. This simple method will usually solve the problem and prevent any data loss.

If that fails, you will need to make a hard drive recovery which can be extremely time-consuming and require special software or skills. Make sure you have regular backups so you don’t lose any important files.

5-Boot Into Safe Mode

If your laptop doesn’t turn on, you should boot into Safe Mode. This will help you troubleshoot and fix any issues before anything else.

To do this, press and hold down the Shift key while you start your laptop up. When the startup menu appears, select Safe Mode from the list and press Enter. After Windows has started in Safe Mode, you can use it to try to fix your problem.

If your laptop doesn’t start up, you might need to replace its battery or motherboard. If that doesn’t work, you’ll need to take it to a technician for further diagnosis.

6-Check For Faulty Or Incompatible Hardware

It is important to verify that the hardware on your laptop is compatible with each other. Often, we can do this by checking for faulty or incompatible hardware. Ensure all cables and connectors properly insert and plugged in, so there isn’t any potential problem later on.

Also, ensure battery power is charged fully, which will help avoid problems during use. Suppose you’re experiencing issues with a particular piece of hardware (for example, a graphics card). In that case, it’s often a good idea to check for updates available for the software installed on the computer – often, these will solve compatibility issues.
