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:
- Overheating:
- High performance laptops like gaming ones can overheat if ventilation is blocked or if the cooling system fails.
- Hardware Failure:
- Components such as the CPU, GPU, or motherboard might have failed.
- Power Issues:
- Problems with the power supply or battery can cause sudden shutdowns.
- 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.
