Black screen blinking cap lock 3x long 5xshort - HP Pavilion x360 – 15-cr0220ng

Pavilion x360 – 15-cr0220ng
Microsoft Windows 10 (64-bit)

i have a HP Pavilion x360 – 15-cr0220ng laptop PC (Seriennummer: 8CG9134QC2), and after updating the bios through HP support Assistant the caps lock light began to blink continuously: 3x long - Pause- 5x short. I've tried everything and looked all over the Internet without success. I've removed the Ram cleaned it, tried another RAM, removed the battery tried to restore the bios through a usb Drive using windows+B,  Windows+V,   B  key Kombination, unplugged the Keyboard trackpad and backlight... but without success. On the Motherboard there is no CMOS Battery. I've used to repair computers in the past so i have a little bit of experiance. Please help me i am having exams and i need the Laptop for Zoom meetings. Thank you in advance.

  

maybe this internet site will help identify my problem: https://support.hp.com/us-en/document/c01732674?openCLC=true

I will upload a video showing the error code

@Yassinov 

First off, removing a CMOS battery on a laptop is a waste of time -- as it does nothing to reset any passwords or locks.

 

Second, that code indicates the CPU can not be detected, meaning that either the CPU has failed, or the motherboard has failed.  Since most CPUs are soldered to the system board on laptops,. that would also mean replacing the entire system board -- and that can cost as much as simply replacing the laptop.
