Hi
You get a LONG (MAJOR) signal category, RED LED &
then a SHORT (MINOR) signal category, WHITE LED.
Major – the category of the error; Minor – specific error in that category
The AUDIBLE repeats 5 times, and the VISUAL until power is removed.
Main- (Mother) Board | 5.2 | The embedded controller cannot find valid firmware.
Controller is missing appropriate ROM. | 1 Remove any recently inserted Hardware. 2 Reset CMOS. 3 Update BIOS while affected components are removed. 4 Test known good component. 5 Replace component or Main-Board as needed. |

Could the CMOS/RTC battery have failed?

Thanks for your answer Lil_Boy_Blue
I found reset CMOS button on main board.
I removed DDR4 Ram and SSD Harddisk drive (Even originally installed before working good this parts). Again same 5 times red 2 times white beep signal i saw.
Later i removed mainboard battery and nothing changed.
