Dell Latitude 5580 possible bios corruption

[gizaha]

Dell latitude 5580, motherboard cdp 80 la-e151p

3 amber 3 white blinks. Dell website sais it's problem "bios recovery" and suggested solution "recovery image not found"
(from here https://www.dell.com/support/manuals...e7a&lang=en-us)

I try plugging charger while pressing ctrl+esc, machine turns on, nothing and after 20 seconds it gives 3 amber 3 white blinks again.

Since ssd is replaced and had clean install windows, i've made a guess that "recovery image" is on disk and it's BIOS recovery image. Am i right?

Dell claims that "Auto-Recovery is only available on BIOS Recovery from hard drive"

In case i'm right and lost the original hdd, how can i restore the bios while keeping the windows key within? (i have ch341 if needed)


THE SOLUTION:
Download from Dell site the bios for the specific laptop. Rename the exe file to BIOS_IMG.RCV and put it in a FAT usb.
Plug the stick to the right usb port (in the left it didn't work)
Plug battery.
Hold ctrl+esc, plugged charger.

Laptop turn on, post, run bios recovery.

At least you go the bloody thing to boot. Dell does NOT make it easy anymore.
