P14s gen 2: BIOS 1.40 adds blacklist, even for secondary SSD

2021-07-08, 18:28 PM

Of course, Lenovo only specs the second M.2 slot in this device for WWAN cards; but in the end it's a PCIe x2 capable slot, and I have been using it without any issues with a second SSD module. But with BIOS version 1.40, the device refuses to even enter the BIOS setup, with an error message about an "unauthorized network card". (There's no network card present.)


Other posts (here, as well has here for the very similar T14 gen 2) have already pointed out that their working WWAN cards were disabled by this BIOS update. But apparently it's more than just a network card blacklist, but anything not on the original parts list is now prohibited. Only option for now seems to be to open the laptop again, take out the SSD, downgrade to 1.37, then put back the SSD; and never do a BIOS update again?


There are plenty of real problems with these machines that could benefit from a BIOS update (as seen on these forums). Why is anyone even spending time on implementing a hardware blacklist? How is that, in any way, the right decision for your customers?


And if it's fair game to disable existing functionality, what's next? Disable non-Lenovo-branded SSD and RAM upgrades? Prevent running Linux on systems only specced for Windows?


The modular extensibility (hardware and software) is one of the main market advantages of these laptops. If I'm looking for a laptop that performs well as originally specced, with no customizations on the user's part, there are plenty of other options; and, quite honestly, they do that better than Lenovo. But Lenovo was pretty much the only name in its niche, designed to be upgraded or side-graded over time, and to be customized as the user requires. But given the lack of resources for detailed technical support, quality control, and fixing of bugs, it seems that Lenovo leadership has decided to gradually exit from that market segment.


It's unfortunate; but I think I'm done trying to debug this laptop for Lenovo, when its priorities are so different. Time to investigate the alternatives.
