TPM UPDATE

2018-06-28, 18:29 PM

Hello,

 

After windows 10 last update, a message came from windows defender about TPM vulnerability, as described here :

 

https://support.microsoft.com/en-us/help/4096377/windows-10-update-security-processor-tpm-firmware

 

On my Thinkpad 13, TPM is infineon IFX 1.2, version 6.40.

 

There is nothing about this update in Vantage (wich seems to be in other Thinkpad models). So I am wondering if I need to proceed to this update manually using Lenovo's TPM firware update utility : https://pcsupport.lenovo.com/fr/fr/downloads/ds501051;

 

Is it really necessary to proceed to this update ?

 

Can't find anything about this on the board.

The TPM firmware update is not installed by Lenovo Vantage or Lenovo System Update.

 

The only way to update the TPM firmware is to install it from here:  https://pcsupport.lenovo.com/in/en/products/LAPTOPS-AND-NETBOOKS/THINKPAD-T-SERIES-LAPTOPS/THINKPAD-T460/downloads/DS501051

Hello,

 

It looks like the fix was introduced in BIOS (UEFI) firmware update version 1.25, which does not clearly indicate the severity of the issue from my reading of it.  The current BIOS version is 1.29, and has a severity of Urgent, so I think it would be a good idea to install the latest BIOS update anyways.

Hello,

 

Yes, BIOS updates are cumulative, so the v1.29 update at https://pcsupport.lenovo.com/us/en/downloads/ds112474 will contain all the previous updates.

Thank you.

 

Does Thinkpad 13 model (20GJ) support the TPM update ? because nothing appears in vantage's updates, neither in support web page.

 

Just want to know if I really need to proceed to this update, and if there is a risk for system stability.

 

Thanks

Re: TPM UPDATE

So being a tp13 owner myself

 

I'm conflicted 

 

Reading the discourse of this TPM issue -- it sounds like a rather large issue.

 

And with the Lenovo warranty terms in mind - I'm unsure if this may null the warranty if the unapproved method solves the problem,..

 

I'm certainly stretching this a bit but an application of a modded bios would loosely be an very bad example but within what a warranty t&C would define.

 

Im sorry and this certainly not something that employees need to deal with right now but I've seen very absurd judgements in tech that more or less contradicted the spirit or intended proper use of a contract

Hello,

 

If you have a ThinkPad 13 (Type 20GJ, 20GK, 20J1 or 20J2), the latest Intel Management Engine Update, Version 11.8.50.3460, can be found at https://pcsupport.lenovo.com/us/en/products/LAPTOPS-AND-NETBOOKS/THINKPAD-13-SERIES-LAPTOP/THINKPAD-13/downloads/DS122138.
