Just downgrade. It is easy and works fine.

Re: T470 unable to detect M.2 SSD 2242 after updates inlcuding BIOS

My problem with T460s seems very similar to what happened to you folks here!! Can you tell me how to downgrade the BIOS? I thought Lenovo said that those newer versions are no longer downgradble....

From the readme for the T460s:

 

Notes:
- If the UEFI BIOS has been updated to version 1.22 or higher, it is no longer
  able to roll back to the version before 1.22 for security improvement.
- If the UEFI BIOS has been updated to version 1.14 or higher, it is no longer
  able to roll back to the version before 1.14 for security improvement.
- If system has Samsung 8GB On-Board Memory,
  system cannot be downgraded BIOS to the version before 1.13.

 

So you may be able to roll back a few versions depending what you're running now.  I'll reply with links in your other thread.

 

For others reading this: my quotes above apply to the T460s, not the T470 in the thread subject.  There is likely similar information in the T470 BIOS readme.

Re: T470 unable to detect M.2 SSD 2242 after updates inlcuding BIOS

I chose the Mydigitalssd Superboot2 M.2 2242 SSD for my T470 a while ago, because as others suggested it was not affected by the BIOS problem (I updated a couple times since then and am now at the most recent BIOS 1.32), uses a modern controller, and $100 for 256GB was very reasonable compared to the other options.  So, as a PSA, if you don't want to deal with waiting for a fix, or having to stay with an older BIOS, or whatever, this is an option.

 

Additional notes:

 

1) You need to initialize the card by going into Disk Management and selecting a boot manager for it, before it can be recognized by Windows.

 

2) Although I had already disabled Fastboot for other reasons, so I don't know if it was necessary in my case, but anyway, there is a warning that comes with the Superboot2 that disabling Fastboot may be necessary for the card to be recognized by the system, so it may be worth a try with Adata, Transcend, or other cards, although it sounds unrelated to the BIOS issue.

Re: T470 unable to detect M.2 SSD 2242 after updates inlcuding BIOS

@pjc123 Superboot2 M.2 2242 SSD seems like a great work around for the issue. Are you having the OS in this SSD in secondory storage?

 

I was planning to have the 500GB hard disk and the m.2 2242 SSD in the other slot and have the OS in the SSD. Do you think this would work?

Re: T470 unable to detect M.2 SSD 2242 after updates inlcuding BIOS

 I have Windows on the HDD and a couple Linuxes on the SSD.  I select which drive to boot from the boot menu. What you want to do seems feasable, but I can't verify it as my setup is different.

The same problem.

Product name: 20HDCTO1WW

There has been no further information for two months. Can the official explain the progress of the problem?
