Disclaimer: Be aware that opening up your laptop may void its warranty, so proceed with caution and at your own risk. It is recommended to take professional help if you are not sure about what to do. The writer of this article will not be responsible for any damages caused due to following the instructions mentioned in this article.
Fix 1: Check the Battery
If your laptop doesn’t turn on, but the power light is on, there may be an issue with the battery. In this case, removing the battery can help you troubleshoot the problem.
The faulty battery can prevent the laptop from turning on even if the power light is on. The laptop cannot draw enough power from the battery to turn on the system.
By removing the battery, you can eliminate the battery as the source of the problem. Once the battery is removed, try turning on the laptop using only the power cord. If the laptop turns on without the battery, then the battery may be the issue, and you may need to replace it.
Suppose the laptop still does not turn on even with the battery removed. In that case, other issues may be at play, such as a faulty power cord, a damaged charging port, or a problem with the motherboard.
Fix 2: Check the Display
The display may have an issue if your laptop doesn’t turn on, but the power light is on. In this case, checking the display can help you troubleshoot the issue.
To check the display, follow these steps:
- Look for signs of life from the display, such as a backlight or flickering. If the display appears to be on, but there is no image, try shining a light on the display to see if you can make out any faint images. This can help you determine the display or graphics card issue.
- Connect the laptop to an external display. This will help you resolve if the issue is with the laptop’s display or the graphics card. Connect the laptop to a monitor or TV. Then, turn on the external display and try to turn on the laptop. If the external display shows an image, the issue is likely with the laptop’s display.
- Check the display cables. If the display cables are loose or damaged, this can cause the display to not work correctly. You may need to open up the laptop and check the connections to check the display cables. This can be a complex process, so it’s best to consult a professional if you need help with how to do this.
Fix 3: Perform a Hard Reset
Another way to solve the ‘laptop won’t turn on, but the power light is on’ issue is by performing a hard reset. This will restore your laptop settings to the factory defaults and clear any errors that may be causing the problem. To do this, you will need to follow these steps:
- Power off your laptop and carefully remove the battery.
- Remove all of the external hardware components from your laptop and disconnect the laptop charger.
- Now press and hold down the power button for about 15-30 seconds to completely drain out any electricity (residual electric charge) inside the laptop.
- Insert the battery in the laptop and reconnect the charger. DO NOT connect any external peripherals right now.
- Press the power button to turn your laptop on.
- The laptop will be turned on, and you will see the manufacturer’s logo (in this case HP).
- Finally, you will get the option to Start Windows Normally.
Note: If your laptop has a non-removable battery, then also you can follow the above steps, except you don’t have to remove the battery by any means. However, since the battery is un-detachable, it might take a longer time to drain the power of the laptop.
Fix 4: Reset the Memory Modules
If your laptop doesn’t turn on, but the power light is on, it could be due to memory module issues. If one of the memory modules is loose, your laptop may not display an image or a black screen. Reseating the memory modules can sometimes resolve this issue. Here are the steps to follow:
- Switch off the laptop and detach the power cord. Before starting any procedure, touch a grounded metal object to discharge static electricity.
- Remove the cover to access the memory.
- Carefully remove the memory modules from the laptop.
- Reinsert all the memory modules, making sure they are securely in place.
- Once the memory modules are reseated, perform any necessary tests to verify that the laptop can start running in the Windows operating system.
By reseating the memory modules, you may be able to resolve the issue. However, suppose the problem persists even after reseating the memory modules. In that case, another underlying issue may require professional assistance to diagnose and fix.
Fix 5: Check the Motherboard Functioning
When a laptop doesn’t turn on, but the power light is on, it may be due to a problem with the motherboard. If the motherboard is malfunctioning or has failed, the laptop may not turn on or on briefly before shutting off. The motherboard can fail for various reasons, including electrical damage, overheating, physical damage, or component failure.
One way to identify if the motherboard is the cause of the issue is to perform a power reset. To do this, disconnect the AC adapter, remove the battery, and press and hold the power button for around 30 seconds. Afterward, reconnect the AC adapter and try turning on the laptop again. If the laptop still doesn’t turn on, the issue may be with the motherboard.
Unfortunately, a failed motherboard is a severe issue, often requiring professional repair or replacement. But, replacing the motherboard can be expensive and may not always be possible, especially in older laptops.
Fix 6: Try Disconnecting Peripherals
If your laptop doesn’t turn on, but the power light is on, there may be an issue with a peripheral device connected to the laptop. In this case, disconnecting the peripherals can help you troubleshoot the problem.
Peripherals such as external HDDs, SSDs, printers, and USB devices can sometimes interfere with the laptop’s startup process. Disconnecting these devices can help determine if one is causing the issue.
To disconnect peripherals, follow these steps:
- Unplug all external devices from the laptop, including USB devices, printers, and external hard drives.
- Turn off the laptop completely and disconnect the power cord from the laptop.
- Wait for a couple of minutes, then reconnect the power cord to the laptop.
- Try turning on the laptop and see if it boots up correctly.
If the laptop turns on and boots up properly after disconnecting the peripherals, the issue was likely caused by one of the peripherals. To determine which peripheral was causing the problem, reconnect each peripheral individually and try turning on the laptop after each one is reconnected. If the laptop stops turning on after reconnecting a certain peripheral, then that peripheral is likely causing the issue.
Fix 7: Check the Power Button
If your laptop doesn’t turn on, but the power light is on, the issue could be with the power button itself. Sometimes, the power button may be stuck or damaged, preventing the laptop from turning on.
To check the power button, follow these steps:
- Check the power button for any physical damage or obstructions. Make sure that the power button is not stuck in the pressed position.
- Press and hold the power button for 20-30 seconds. This can reset the laptop and allow it to turn on.
- Test the power button using an external keyboard. If the laptop has an external keyboard, try pressing the power button on the keyboard to see if the laptop turns on. If it does, this may indicate an issue with the laptop’s internal power button.
Fix 8: Get It Checked by the Professionals
Suppose you have exhausted all the above steps, and your laptop won’t turn on. In that case, it’s best to seek professional repair assistance. A certified technician can quickly and efficiently diagnose and fix any issues with your laptop.
Taking your laptop to a professional technician is a hassle-free and cost-effective way to get it up and running again. However, choose a reliable technician to help you solve the issue quickly and effectively. Don’t hesitate to ask for recommendations or reviews before entrusting your laptop to a repair shop or technician.
