You check the motherboard. It should say "DA0R09MB6H1" on it.
Hi. Ive been directed here by a different forum, to this specific thread. It seems I am after this file but...my dell inspirion 7720 board number is DAORO9MB6H3 REV: H3. 3 rather than 1 at the end
Will this file you've shared in the thread work for my motherboard?

It's better to upload your Original Backup, write your Device Service Tag and mention your Device Problem.
Someone here will try to help you.

I was facing similar problem. After turn-on there was black screen without screen backlight. Pressing "D" + "PowerBtn" runs colored display test, CPU fan running at full speed. I tried to upload firmware from this topic. CPU fan becomes turned off but the screen still black. I tried to re-upload "original" backup-ed firmware and fortunately screen becomes alive. I was able to run bios and diagnostic tests. There is a difference in hash sums between firmware from this topic and mine. I leave it here just in case.
