Hi @thiaaety 

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your laptop won’t power on and the screen was flashing before going black, it could indicate a few potential issues. Here are some troubleshooting steps you can try:

1. Check Power Supply

• Ensure the Laptop is Charged: Connect your laptop to the power adapter and check if the charging light turns on. Leave it plugged in for at least 15-30 minutes.
• Inspect the Adapter and Cable: Look for any signs of damage. If possible, try using a different power adapter that is compatible with your laptop.

2. Perform a Hard Reset

• Disconnect the power adapter and remove the battery (if it’s removable).
• Press and hold the power button for about 15 seconds to discharge any residual power.
• Reinsert the battery (if applicable) and plug the power adapter back in. Then try turning it on again.

3. Check for External Devices

• Disconnect all external devices (USB drives, printers, etc.) and try powering on the laptop again. Sometimes peripherals can cause boot issues.

4. Inspect the Display

• If you see no signs of power, try connecting your laptop to an external monitor. This can help determine if the issue is with the screen itself or with the laptop's internal components.

5. Boot in Safe Mode

• If the laptop powers on but the screen remains black, try booting into Safe Mode. For many laptops, you can do this by pressing F8 or Shift + F8 during startup. If you see the boot menu, select Safe Mode.

6. Check for Hardware Issues

• If you hear beeping sounds during startup, this can indicate hardware issues. Could you share the beeping codes?

I hope this helps.

Take care and have a good day.
