On Board Ram Disable via Bios Editing

[f@brice]

Hello,
Can somebody help me remove onboard ram on Lenovo T15.
I allready tryed with BIOS memory SPD removal tool, but it is not working.
Type 20S7-S2JW00 Serial PF-2T1A26

Lenovo is not easy, so...
try this and report please

I just checked and there is no difference between this file and the one made by spd removal tool. The hexer script for ram removal also makes the same file.

Spd removal tool finds 16 to remove. Probably not all need to be removed. Anyone knows wich should i mark ?

Removing only the SPD entries isn`t going to work. There`s lots more to it, it`s complicated. The ram part numbers are in the premem PEI sections. I don`t think that filling the names with 00`s would work either.

I try to learn and do as much as possibile myself, but this is beyond my knowlage

It`s beyond mine as well. Have you checked to see if RAM can be disable via resistor straps.

@mhd bero, You can try this and report result, please, but lenovo...

Unfortunately, it didn't work, knowing that there is a dynamic ampere draw without disable with the device's BIOS file. As for the BIOS that you shared with me, the ampere draw is not dynamic.

That is the next step
Thankyou for help

My onboard ram is broken. I need to disable it on BIOS and use only the additional 8gb ram that I added later. Can you help me with it? I don't know how to extract and link you my current BIOS. This is my first time to do something like this. Please help me I need my computer.

You would need an SPI programmer to make a backup of the bios chip on the motherboard. https://www.badcaps.net/forum/troubl...21#post1622421 .Patching the bios does not work on every laptop, sometimes it can only be disabled by changing resistors around on the motherboard. Search the forum to see if anyone else has had success or not patching the bios or by moving resistors for this model https://www.badcaps.net/search?q=Ide...DA05+ram%22%7D

I just used an updated BIOS(BIG MISTAKE, i wish i used the current bios version) that I downloaded from Lenovo website and my laptop has black screen now. Tried all the methods I saw on the internet. Nothing works.
