Good day,
In my hands I have a Thinkpad T14 gen 1 (20UD002BIX) showing sporadic BSOD issues caused by failing onboard soldered RAM. I suspect disabling the onboard RAM via a bios mod would do the trick.
The laptop has already the latest updates as well as latest bios 1.51 as of today.
I informed myself in an attempt to DIY my way to victory but it left me with more questions than answers. This is not a BIOS request, what I really need is somebody to verify that the following procedure is correct.
Step 1: grab a bios image:
- Method 1: from the official website: Downloaded "r1buj82w.exe" from here, run it, selected "extract only" to have the installer extract to a directory. Found a "$0AR1B00.FL1" file within, roughly 17MB big.
- Method 2: extract a dump from the machine itself. I used Universal BIOS Backup ToolKit 2.0, the created dump file is exactly 16MB big.
A cursory inspection shows that there are many differences between the FL1 and the dump file. Which one is best to go for in your opinion?
Step 2: apply the script
I found a script in this thread, however it's unclear if i should apply it directly to that FL1 file, as in this other post it's said that I need to do a whole bunch of operations on that file before it becomes useful and that was for a different laptop model so I stopped there.
If I run the script directly to the FL1 file, it performs 22 replacements. If I run it on the dump, it only does 21.
Step 3: flash the newly create image.
I didn't find a way to flash the new bios once I (hopefully) have it. The laptop doesn't seem to offer a native way to do it from bios interface. Is Phoenix UEFI Winflash v1.5.66 ok? Also I thought it might be possible to overwrite the FL1 file in the extracted folder and rerun the provided Winuptp64.exe inside that same folder, not sure this would work tho.
