Technical Support HP OMEN 15-ek0008ca flashing 5-3

[Mamdouh]

This HP , the wifi stopped then after it would not POST, the caps lock blinks 5-3.
I left it for 2 months. today when I power it, it gave me BIOS unlocked status , Then CMOS checksum invalid, CMOS reset (502), click to reset. then started blinking after reboot.
I managed to flash the BIOS using USB memory and Windows key +B. It did show the successful writing of the bios, then I got same flashing 5 long- 3 short.

hp 5 slow blinks 3 fast:
This condition indicates the embedded controller cannot reach the BIOS within the established time limit. Remove all accessory devices from the notebook and try to start it. Try a power refresh to hopefully get it working again.

In particular, remove the wifi card and test it
