need bios dump dell latitude 5420 (cpu 11th)

[SMDFlea]

I can see the screen on the laptop but backlight is not turning on. I see a dim screen on laptop and when i presss any key on th ekeyboard it maskes noise.

It`s not a bios problem, it`s hardware.

Hello everyone

I'm having a problem. While updating my laptop's BIOS, it became corrupted and won't exit recovery mode. I already purchased the CH341A reprogrammer and installed the program and drivers.

I verified that it was working correctly, read the chip, and backed up the version I had, but now I can't reprogram the correct version. The files are larger than the chip supports. I have a Winbond 25Q80DVSIG chip, and it appears to be 8 MBits.
Could someone help me find the correct BIN file? Or, if so, tell me what I'm doing wrong.

Thank you very much.

You chose the wrong chip. The 25Q80DVSIG is for the thunderbolt firmware or something else, it is not the bios chip.
