Lenovo G50-80
Model name: 80E5
S/N: PF0FF9RK
Board model: ACLU3/ACLU4 UMA NM-A362 Rev 1.0
Problem:
All voltages are present on the board but no image on screen.
tested new memory and new screen.
Using bench power supply to power laptop shows board drawing 15ma standy and 475a when power button is pressed so I can see the EC chip is working as it is monitoring the power button.
Cou also gets hot as I believe it should.
All voltages apropriatly present on board. This leads me to believe that it is possibly a bios issue.
I have already tried copying original bios DMI myself to a vergin bios but from the post I found regrding copying DMI for this laptop model I can find the start offset mentioned but not the end offset. Thus I am unsure how to poceed.
Help will be apreciated but if I am still in violation of rules I will remove my post.

Thank you all for your time.
DMI offsets 29A000 - 29BFFF
You can use the bios in post #2 replacing the DMI from your backup.

Yes I saw those offsets but my problem is when I look at the bios in a hex editor I cannot find the 29BFFFh offset. Only the start one. So not sure why this bios is diffrent. The last 29B entry in the original bios is 29BFF0.

Offsets in your original bios Put your cursor on the last FC it will be 29BFFF .The first FC on that last line is 29BFF0
