Hi @Serge953227,

Welcome to HP Support Community.  

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

A long beep followed by two short beeps on an HP OMEN Laptop generally indicates a memory (RAM) error. This beep code pattern is often used by BIOS (Basic Input/Output System) to indicate a hardware problem during the startup process.

To troubleshoot this issue, you can try the following steps.

1. Power off your laptop and disconnect the power cord.
2. Open the access panel to the RAM modules on the bottom of your laptop.
3. Ensure that the RAM modules are properly seated in their slots. Gently remove and reinsert them to make sure they are securely connected.
4. If your laptop has multiple RAM modules, try booting with each module individually to identify if any specific module is causing the issue. This can help you determine if one of the RAM modules is faulty.
5. If you have spare compatible RAM modules available, you can try replacing the existing ones to see if the problem persists.
6. Check for any visible signs of damage or corrosion on the RAM modules or their slots. Clean them if necessary.
7. After performing the above steps, close the access panel, reconnect the power cord, and power on your laptop to see if the issue is resolved.

I hope this helps. 
 

Take care and have a good day.
