Request to fix TOLUD in newer BIOS files

[PZF]

 Looks like I end up hard-switching X220T between 3 Gb for desktop mode and 8 Gb for portable one. Whoa, that even sounds weird... I wonder why I didn't stuck with Lifebook series

How can one distinguish X220 with 8DHT chipset (old, downgradeable BIOS) from X220 with 8ZHT (non-downgradeable) in a computer store?
Is there any information in BIOS menu or on POST screen?

bump^...any updates as to whether the lenovo engineers are willing to help resolve this problem?

Hi Lenovo Staff,

I wanted to let you know that I also need this fix in newer bios updates along with the msata fixes introduced in 1.18/9.  Thanks and keep us posted!

Please ask Lenovo engineering if they will provide a fix and in what timeframe

I concur, the DIY eGPU will very soon have pci-e 2.0 link speed so a X220 will be a serious contender to be a portable, gaming-capable desktop replacement. I've been asked several times now by NBR users whether I can recommend this as a solution which I am reluctant to do so due to this TOLUD issue, instead referring interested parties to this thread with details "it's being looked at to be fixed".

So could Lenovo engineering please advise if they will fix this issue and what timeframe?

If not immediately solvable (< 1 month) then I'll need to note the  X220 as being only 3GB DIY eGPU capable in the SB notebooks for eGPU list due to the undocumented change of TOLUD from 3.0GB to 3.5GB in bios versions newer than 1.12.

I am waiting for a fix for this before pulling the trigger on purchasing an i5 X220, and the eGPU market is growing by the day with players like Sony jumping on board. Even if it is an alternate bios that is only produced once, at least then we could have both an eGPU and the important fixes that plagued this model from release.

Does the new BIOS have 3.5 TOLUD?

x220 is now 1.21

Anyone check if they have a bump back? It's not documented, but neither was the removal documented.

Just one more vote for a TOLUD fix.

I've been waiting for about 3 weeks to see if this TOLUD defect will be corrected. Once a confirmation is made, I will pull the trigger on buying an X220, otherwise, I'll just have to look elsewhere at other brands if Lenovo denies this is a defect and is unwilling to fix it.

Why do I call it a defect? In software development, you need to regression test to ensure previously working functions are not broken by a new software release, and I would have to say this definitely is the case. The functionality that is broken by the newer firmware is enough to make me hold off on buying the X220.

There also happens to be no reasonable workaround.

Can a Lenovo representative please state if this defect will be resolved by Sunday?

Hello all first time poster here,

I would like to also request that the proper authorities at Lenovo review this again, and announce if they plan to fix this.  I do not own any Lenovo products, but I was dead set on buying the x220 for school, and being able to use the express card slot to its full capacity by connecting it to third party devices was one of the primary reasons for choosing to go with the x220, as it is the computer I want.  The lenovo x220 was meant to be my primary computer as well, so I would like to have the capability to use the express card slot to be able to hook up a eGPU to it.  This capability does in fact weigh very heavily on whether or not I will purchase this product.

I am glad I came across this thread before I made the purchase, as I still have some time before I will be buying a new PC.  I will be watching this thread carefully in hopes that this request is acted on accordingly

Good day.
