My omen 15 power button blink and screen never turn on

Hi @Dylster, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
If your OMEN 15 power button blinks but the screen never turns on, it could indicate a hardware failure or a BIOS issue. Try these troubleshooting steps:

Check the Blink Pattern

Count the number of blinks—HP laptops use a blink code to indicate errors:

• 1 long + 2 short → BIOS corruption
• 1 long + 3 short → Memory issue
• 2 blinks → CPU failure
• 3 blinks → RAM failure
• 5 blinks → Motherboard issue

Perform a Hard Reset

1. Turn off the laptop.
2. Disconnect charger and peripherals.
3. Press and hold the power button for 30 seconds.
4. Reconnect only the charger and try turning it on.

Try a BIOS Recovery

Since you've had BIOS-related issues before, try recovering it:

1. Turn off the laptop.
2. Press and hold Windows + B (or Windows + V).
3. While holding, press the power button for 3-5 seconds, then release all keys.
4. If the BIOS recovery screen appears, follow the instructions.

Check RAM and Reseat It

A faulty or loose RAM module can cause this issue:

1. Remove the bottom panel (if you're comfortable).
2. Locate the RAM sticks.
3. Remove and reseat them firmly in place.
4. Try booting again.

External Display Test

If the laptop boots but the screen is black, try:

• Connecting to an external monitor via HDMI.
• Pressing Windows + P and selecting Duplicate.
• If an external screen works, the internal display or GPU might be faulty.

Check for Overheating Issues

Since your OMEN 15 has a history of overheating, a thermal failure could have caused this. Try:

• Removing the bottom panel to check for dust buildup.
• Repasting the CPU/GPU thermal paste (if it's been a long time).

I hope this helps. 

Take care and have a good day.
