Faulty Motherboard
The motherboard is the brain of your laptop, and any issues with it can cause a range of problems, including no display. Faulty capacitors, damaged components, or a failing motherboard can all contribute to this issue.
GPU Failure
The graphics processing unit (GPU) is responsible for rendering images on the screen. If the GPU fails, you might not see anything on the screen, even though the laptop is turning on.
Display-Related Issues
Faulty Display Cable
The display cable connects the screen to the motherboard. If the cable is damaged or faulty, it can prevent the screen from receiving the necessary signals to display anything.
Screen Failure
A failing or failed screen can also cause this issue. If the screen is damaged or malfunctioning, it might not be able to display anything, even though the laptop is turning on.
Software-Related Issues
Corrupted BIOS or UEFI Firmware
The BIOS or UEFI firmware is responsible for initializing the hardware components of your laptop. If the firmware is corrupted, it can prevent the laptop from booting up properly, resulting in a blank screen.
Operating System Issues
A corrupted operating system or a faulty driver can also cause this issue. If the operating system is not functioning properly, it might not be able to display anything on the screen.
Troubleshooting Steps
Now that we’ve identified the possible causes, let’s move on to some troubleshooting steps to help you identify and fix the issue:
Basic Troubleshooting
Try a Different Power Source
Try plugging your laptop into a different power source to rule out any issues with the power cord or adapter.

What could be the reason behind my HP laptop turning on but not displaying?
The most common reason behind this issue is a faulty or loose connection of the video cable. It’s possible that the video cable connecting the motherboard to the LCD screen has come loose, causing the display to malfunction. Another possibility is that the LCD screen itself is damaged or faulty, preventing it from displaying any images.
However, there could be other reasons behind this issue as well. For instance, the backlight of the LCD screen might be faulty, or the inverter that powers the backlight could be malfunctioning. In some cases, the problem might be more complex and could be related to the motherboard or the GPU.
Could a faulty power supply be the culprit behind this issue?
Yes, a faulty power supply can indeed cause your HP laptop to turn on but not display. If the power supply is not providing the necessary power to the components, it can prevent the display from functioning properly. The power supply could be faulty or worn out, causing voltage drops that affect the display.
In this case, try using a different power supply or replacing the existing one to see if the issue resolves. Make sure to use a power supply that is compatible with your laptop model and has the same voltage and wattage ratings. If the issue persists, it’s likely that the problem lies elsewhere.
Is it possible that the issue is related to the motherboard?
Yes, it’s possible that the issue is related to the motherboard. The motherboard is the main circuit board of your laptop, and it contains various components that control the display. If the motherboard is faulty, it can cause display issues, including the laptop turning on but not displaying.
In this case, diagnosing the issue can be complex and may require professional assistance. If you’re not experienced in troubleshooting and repairing laptop motherboards, it’s recommended to take your laptop to a professional repair service. They can diagnose the issue and provide a repair or replacement quote.
Could a BIOS or UEFI firmware issue be causing the problem?
Yes, a BIOS or UEFI firmware issue can cause your HP laptop to turn on but not display. The BIOS or UEFI firmware is responsible for controlling the laptop’s hardware components, including the display. If the firmware is corrupted or outdated, it can cause display issues.
In this case, try updating the BIOS or UEFI firmware to the latest version. You can download the latest firmware from the HP website and follow their instructions to update it. If the issue persists, you may need to reset the BIOS or UEFI firmware to its default settings.
What if the issue is related to the RAM or storage?
It’s unlikely that the issue is related to the RAM or storage, but it’s not impossible. If the RAM is faulty or not seated properly, it can cause display issues. Similarly, if the storage drive is faulty or corrupted, it can prevent the laptop from booting up properly, including displaying any images.
In this case, try removing one or both RAM sticks and see if the issue resolves. If you have multiple storage drives, try booting up the laptop with a different drive. If the issue persists, it’s likely that the problem lies elsewhere.
Can a virus or malware cause this issue?
It’s highly unlikely that a virus or malware can cause your HP laptop to turn on but not display. Viruses and malware typically affect the operating system and applications, not the hardware components like the display.
However, if your laptop is infected with a virus or malware, it can cause system crashes and freezes, which might prevent the display from functioning properly. In this case, try booting up your laptop in safe mode and running a virus scan to detect and remove any malware. If the issue persists, it’s likely that the problem lies elsewhere.
Is it worth trying to repair my HP laptop or should I replace it?
If your HP laptop is still under warranty, it’s worth trying to repair it. HP may be able to repair or replace the laptop for free or at a reduced cost. Even if the warranty has expired, if the laptop is relatively new or has sentimental value, it might be worth repairing.
However, if the laptop is old or the repair cost is high, it might be more cost-effective to replace it with a new one. Consider the cost of repair, the age of the laptop, and your needs before making a decision. If you’re not sure, consult with a professional repair service for their opinion.
