leonovo ideapad 3 15alc6

[ecs10]

I'm running a Lenovo Ideapad 3 15ALC6 82MF (Brazilian variant) with GLCN68WW bios which is modded with resizable bar DXE driver.
I have bricked my bios before messing with some advanced options, then I managed to fix it with a CH341 programmer; I tried to import DMI info, serial, MTM to the new bios file with a script posted on the forum but it didn't worked and now I'm using the laptop with no serial number basically.

After I recovered it, doing some basic reboots, the bios bricks itself; I have checked for silent bios updates though I don't have Lenovo bloatware installed on my computer, disabled some Microsoft bios related drivers and so on... But it keeps self-bricking. This is the 4th time fixing through programmer and I don't know what I should do. The laptop itself runs fine if I keep it turned on all the time, but it may brick with a random reboot.

Setup: Lenovo Ideapad 3 15ALC6
MTM: 82MFS00000
SN: PE0AECQ7
Current bios file attached (I don't have old/original bios)

Ty very much, my friend! One more question, how shall I proceed to mod 68 version with ReBAR DXE without losing DMI info?
Update it, backup through programmer and add driver with UEFITool?

[m1ch43lzm]

The update .exe will also update EC firmware, that's the idea, else i would have given you GLCN68WW version
Check EC version on BIOS setup, should be GLEC60WW after updating (if you don't have that version already)
Test the stock BIOS first for few days to see how it behaves

Yes you can do it that way
DMI is stored at 1000h-2FFFh
Maybe your BIOS mod is the source of the bricking

Sure, I'll take a look into this. My EC is already GLEC60WW. Do you have any idea of why is the bios behaving this way? Everything's running fine, no hangs, freezes or bsods. Just a delayed brick, kind of a time bomb triggering every reboot; and the mod not gave me any signal of messing up the functionality, even when stressing the hardware while playing games.

I have flashed your 51' version now. The system feels more responsive... With less latency. Dunno if placebo. Anyway, I'm thinking of keeping this version instead of updating to 68. Thank you very much again.
