Hi Guys

Trying to repair a Lenovo Ideapad3 Model 15IAU7. Getting power light bit no signs of life. I can feel the CPU heating but, But no display or fan spin. Hoping it's just a corrupt bios. There are 2 chips on the motherboard, i usually desolder the wrong one first lol... so i went for the bigger capacity one this time.
Ive attached th bios file which was read ad verified after removal from the motherboard. I would be greatful if someone mor knowlegable than me can take a look and repair or possible supply a clean image. also advise if i need to add in any blocks for serila number etc... into new clean image

As always much appreciated
Thanks in adance

I'm confused. What's the importance of DMI. Do I have to put some thing in that area?
