Hi @Arda678,

Welcome to HP Support Community.

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

A sudden failure of your OMEN by HP 16.1-inch gaming laptop accompanied by a high-pitched sound could be indicative of a few potential issues. Here are some common causes and steps to troubleshoot.

Possible Causes:

1. Overheating:
   • High performance laptops like gaming ones can overheat if ventilation is blocked or if the cooling system fails.
2. Hardware Failure:
   • Components such as the CPU, GPU, or motherboard might have failed.
3. Power Issues:
   • Problems with the power supply or battery can cause sudden shutdowns.
4. Fan Issues:
   • A malfunctioning fan could cause overheating and a high-pitched sound.

Troubleshooting Steps:

Power Cycle the Laptop:

• Disconnect the laptop from the power source.
• Remove the battery if possible.
• Hold down the power button for about 15-30 seconds to discharge any residual power.
• Reconnect the power and try turning on the laptop again.

Check for Overheating:

• Ensure the laptop is on a hard, flat surface to allow proper ventilation.
• Inspect the cooling vents for dust and clean them if necessary using compressed air.

Listen to the Sound:

• Identify if the high-pitched sound is coming from the fans, hard drive, or another component.
• A high-pitched whine could indicate a failing fan or capacitor.

Test the Power Adapter:

• Make sure the power adapter is working correctly.
• Try using a different, compatible power adapter if available.

Remove External Devices:

• Disconnect all external devices (USB drives, external hard drives, etc.) and try restarting the laptop.

Boot in Safe Mode:

• Try to boot the laptop in Safe Mode to see if it can start without the full set of drivers and software running.
• Press F8 or Shift + F8 during startup to access Safe Mode.

Check the Battery:

• If the laptop works without the battery but fails with it, the battery might be defective.

I hope this helps.

Take care and have a good day.
