Laptop wont boot

Hello team,

My laptop blinks 2 amber and 2 white and it shows a blank screen and won't boot. At times, when I am lucky I would be able to get into the bios and diagnostic section. At one point, I was able to diagnose and scan the device and i remember the code was like 2000-1114, not sure if it was correct. I tried many methods provided on google. I tried bios update from usb, but it did not recognize the bootable drive and that was the last time I was able to boot into something. Any ideas?
