Re: T490 Automated Bios update

2019-09-03, 23:31 PM

Dear customers,

we are very sorry all the WhiskeyLake products' BIOS didn't support the silent installation option.

The reason to disable the silent installation on WhiskeyLake products was we found potential hang up issue when perform suspend after BIOS update. Because the silent install option allows end user to perform suspend action right after BIOS update, we disabled it for a while.

 

Now, we resume to support silent installation option for all WhiskeyLake when target system has certain level of the BIOS. Please refer to the each readme file for the BIOS level.

Any update on when a fix for this will be made available from Lenovo? Or, at least a confirmation that any system on Bios v1.49+ will be able to be upgraded silently by a future Bios release?

How much longer until a new BIOS is released that addresses this issue ?

 and ,

 

In the latest BIOS Update Readme which right now is version n2iuj13w, it states in the change notes:

 

--------------------------------------------------------------------------------
CHANGES IN THIS RELEASE
  Version 1.52

[Important updates]
- Update EXE/Readme to support silent installation option.

[New functions or enhancements]
  Nothing

[Problem fixes]
  Nothing

and further down:

<1.52>
 UEFI: 1.52 / ECP: 1.13
- [Important] Update EXE/Readme to support silent installation option.

<1.52>
 UEFI: 1.52 / ECP: 1.13
- [Important] Update includes a security fix.
- (Fix) Fix graphic performance lack problem on hybrid graphic system.
- (New) Support for non-Absolute Persistence Module version of UEFI BIOS.
- (New) Support graphic BIOS setup menu.

We also include in the readme the Caution information at the top about if the ECP is on 1.09, you will need to install 1.12 first then update the BIOS to 1.52/1.13.

--------------------------------------------------------------------------------
CAUTION

  If ECP version is 1.09, update ECP to 1.12(n2iuj11w) or higher version prior to
  update UEFI BIOS. Otherwise, system may hang in UEFI BIOS updating process.

--------------------------------------------------------------------------------

 

Is your ECP updated to or beyond 1.12? If so, have you downloaded and tested the BIOS n2iuj13w package silently?

Hi,

Our machines are the T490s (Type 20NX), which do not seem to have this newer v1.52 BIOS released yet.

 

https://pcsupport.lenovo.com/au/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t490s-type-20nx-20ny/downloads/driver-list/component?name=BIOS%2FUEFI

 

Sounds like it might not be too far away though, if the non-S version of the T490 now has the fix ?

 

Regards,

The T490, P43s, T590, and P53s all utilize the same BIOS.  The T490s and X390 utilize the same BIOS.  I updated the T490s thread with similar information, just different numerical versions and package IDs.

Yes, found v1.52 in the driver matrix on the newly designed web page and it worked. 

 

Feedback - When I went to look for new Bios versions available for download, the summary page showed "(none)-1.12 " under the Version column and I didn't think a new one had been released. After I clicked on the drop-down arrow under See Files, the older version and the newest v1.52 versions appeared in the list. Recommend to have the summary page show the latest version number available to make it more obvious when a new download version is available.

Thank you for the feedback.  I agree that it could be misleading, like there isn't a newer update out there.  I think the web content team is trying to assist with getting focus on the ECP update and so they are keeping the none-1.12 ECP version there to get people to look.  My best guess.  I will pass along the information that the continual usage is confusing to our customer base.

As of 10/8, it looks like 1.54 is available now as the latest version for the T490/T590.

 

I had the same issue when first searching as well.  Looks like 1.54 is only published on the web model page but not the Driver Matrix page yet (hopefully soon for automation purposes)

 

This link for the T490 has the versions expanded here
