Lenovo Legion 5 15IAH7 - NM-E241 Rev 1.0 - BIOS fix needed

[peste]

I have tried that unfortunately but I'm still getting a black screen.

maybe the laptop has another problem..check the voltages on the coils 19V,5V,3.3v,etc..

[TJ M]

you have everything you need at post #8

I managed to get it to boot to bios, still freezes when trying to boot to windows. However, I am getting Serial Number and MTM Invalid in the Bios Information.

Thank you.
i have wrote it and all my serial number etc are back.

However, it still won't go past the loading screen (attached below). I've ran the diagnostic tests but have had no issues. What else can I do?

Secure boot enabled or disabled ?

[TJ M]

Secure boot is disabled

Thanks a lot!!!!
I just wanted to try this version, but unfortunately while desoldering one leg is broken off of one chip...

Now I have to order a replacement (as a private person this seems really difficult... I don't want to order 2000 pieces at once )

As soon as I got the new chip, I'll try it again

So did you fix it ? Because I have the same exact problem, please help me

Hey, no I gave up on this thing.
didn't manage to order a replacement IC in my country.
So I sold it as defective for parts

Thank you for replying, so the bios wasn't the problem

[Mirenia]

I broke the BIOS Chip and couldn't order a replacement.
So I never figured out if it was the BIOS or not.
