POWER ON NO DISPLAY TROUBLESHOOTING

🛠️ If your laptop powers on but shows no display, here’s a basic troubleshooting checklist to help you narrow down the issue:

🔌 1. Check Power and Connections

  • Ensure the power adapter is plugged in and the battery is charged.
  • Look for signs of life: fan noise, LED indicators, keyboard backlight.
  • Try a hard reset: unplug charger, remove battery (if possible), hold power button for 15 seconds, then reconnect and power on.

🖥️ 2. Test with an External Monitor

  • Connect your laptop to an external display via HDMI or VGA.
  • If the external monitor works, the issue may be with the laptop screen or backlight.

💡 3. Use the Bright Light Test

  • Shine a flashlight directly on the screen. If you see a faint image, the backlight or inverter may be faulty.

🧠 4. Reseat or Replace RAM

  • Remove and reinsert RAM sticks one at a time.
  • Try using a known working RAM stick if available.

⚙️ 5. Boot into Safe Mode

  • Force shutdown and restart multiple times to trigger Windows Recovery Environment.
  • Choose “Safe Mode” to check if the issue is software-related.

🔄 6. Reset BIOS or CMOS

  • Some laptops allow BIOS recovery by pressing specific keys (e.g., Ctrl + Esc while plugging in power).
  • You can also try removing the CMOS battery (if accessible) for a few minutes.

🧰 7. Update or Reinstall Drivers

  • If you can boot into Safe Mode or external display works, update graphics drivers via Device Manager.

🧪 8. Consider Hardware Failure

  • If none of the above work, the issue could be with the motherboard, GPU, or screen cable.
  • Seek professional repair if you’re not comfortable opening the laptop.
