Hi masters, is here anyone able to have a look, if this BIOS file contain windows OEM key? Need to transplate it to new file, but no luck. Hex editor with 010000000000000001000000000000001d000000 show nothing. Can not find serial number as well, I bellieve I missed something for these newer bioses.

PCH should be new and soldered well, original one was shorted. I found, that 10Mohm R262 was missing (probably when I was taking epoxy from corners), put it back, now bootloop 0,6A goes directly to 0...could this missing resistor kill crystal?...

Same issue bro, take 1 minute to get picture, after that FANs at full speed, than goes off. In your files, ME region is cleaned? If so, I have to look for hardware failure.Leave a comment:

Lenovo Legion PRO 5 16IRX8, i9+RTX4070
Hi masters, anyone can help me with BIOS? Long story short, spilled unit, did not start at all. Found two burned resistors in 3.3/5V step down controler. Now unit start, but it takes 30-40 second to get a picture and than FANs start run at full speed and turn off after 20 seconds, so could be ME corrupted...

Hi masters, I have
Legion Y540-17IRH (81Q4)
SN: PF28T3J0
MTM: 81Q400G7PB
It starts, in left top corner blinks white underscore 3 times, no Legion Logo, just backlight is on.
I tried to flash hoaca388 BIOS from post #2 and I got artifacts on screen. If I went to bios, "Discrete graphic" option was greyed out, no changes available.
Is it because this bios is for different GPU?
My BIOS attached, can anyone have a look please.
Thanks in advance....Leave a comment:

Hi, did not work, I finally used original EC file and your last main BIOS dump. Put DMI back right in BIOS after boot. All works well now.
