Experiencing laptop screen issues is common and can stem from various reasons. There are typically two scenarios: the laptop doesn't power up, or it runs but doesn't display. Let's delve into the causes and solutions for these issues in this article.
Laptop Not Running and Screen Won't Display
Laptop Power Adapter Failure
- Issue and Cause: If the laptop's power adapter is damaged, the machine won't power up, and the charging light won't illuminate. You may even hear popping sounds. Possible causes include a damaged charging cable or charging port.
- Fixing the Problem: To address this issue, consider buying a new power cable with the same wattage to test on your laptop. Additionally, inspect the charging port on your laptop and replace it if there are signs of damage.
Laptop Excessively Radiates Heat
- Issue and Cause: When a laptop operates beyond its capacity, it generates a significant amount of heat and may automatically shut down. This can occur due to an aging laptop, poor cooling, and prolonged usage without breaks, leading to overheating.
- Fixing the Problem: If faced with this situation, allow the laptop to cool completely before attempting to restart. Additionally, perform laptop maintenance every six months to optimize its operational efficiency.
Laptop Power Supply to Mainboard Malfunction
- Issue and Cause: When facing power supply issues to the mainboard, the laptop experiences erratic power-up behavior. If plugged in, both the power and charging indicators remain off. This issue occurs due to unstable power supply leading to the burning of the chipset, RAM power supply, CPU power supply, or 3 – 5V power supply component.
- Fixing the Problem: Take your laptop to a repair center for thorough inspection and replacement of the power supply to the mainboard, costing approximately 500,000 to 1,000,000 VND.
Laptop Doesn't Display, but the Fan Keeps Running
Laptop High Voltage Board Damage
- Status and Cause: Laptop and fan continue working, but the screen remains dark or displays blurry images. This condition is likely due to a malfunction in the high-voltage circuit on the laptop.
- Fixing the Problem: If the high-voltage board is damaged, you can quickly replace it at a relatively low cost.
Laptop Screen Malfunction
- Status and Cause: The screen exhibits cracks, dim or completely black spots, often resulting from the laptop being subjected to strong impacts during movement or usage.
- Fixing the Problem: Test connecting your laptop screen to an external display via VGA or HDMI. If the image appears on the new screen, it indicates damage to your laptop screen. You can reduce costs by replacing it with a used screen.
Loose or Dirty RAM
- Status and Cause: When RAM is loose, damaged, or has dirty contact pins, the laptop may experience screen flickering, continuous restarts, and beeping sounds.
- Fixing the Problem: Easily resolve this issue by cleaning the RAM contact pins. In case of damaged RAM, replacement is necessary.
Laptop BIOS Error
- Status and Cause: When the laptop runs out of BIOS battery or encounters BIOS power supply errors, the screen will only display the black and white BIOS interface during startup.
- Fixing the Problem: Check if the BIOS power supply chipset is damaged. If not, consider updating the BIOS version or replacing the battery.
Some Other Issues Related to Laptop Screens
- Cost of Replacing a Laptop Screen
A new laptop screen costs around 700,000 – 2,500,000 VND depending on the panel type (VA, TN, IPS, touch) and size.
- Dealing with Moisture on a Laptop Screen
If your laptop screen gets damp, you can turn off the laptop and use moisture-absorbing packets, rice packs, or a hairdryer to address the issue.
So now you have a basic understanding of troubleshooting a laptop not displaying on the screen. If you lack experience, it's advisable to take your device to an authorized service center for assistance.
