I need my laptop back! Here is the requested info:
my 'Lenovo Service Request Confirmation' - 402D7D8
...and Win10 has been running fine for months and months; i was not in the process of upgrading to 10.

It's been 3 days since the last message now.
I'm guessing that engineering still haven't managed to replicate the issue. Can we at least get some movement from support to commit to board replacements for the affected laptops, including those that aren't under warranty?
My client isn't going to be particularly happy about a trashed T450s from a BIOS update.

I'm having the exact same issue after upgrading to 1.25. System was running, did bios upgrade, but did not manage to get into windows afterwards
Only upgraded because the update was marked critical.
Is there any resolution as of now?
Edit to answer the question list:
My service request # is: 402F9G4
Did it occur on UMA or SWG system? UMA
Which OS? Win7, x86, or x64? Was it Legacy installed or UEFI installed? Windows 7 x64 as installed by lenovo, did not reinstall it.
Was the BIOS updated by Winflash package or ISO package? Through the Winflash package
Were there any specific changes in the BIOS setup before BIOS was flashed Not that I know of.
BIOS Version: JBET61WW (1.25)
Embedded Controller Version: JBHT17WW (1.04)
ME Firmware Version: 10.0.38.1000
CPY Type: I7-5600U
Edit 2: After disabling everything that is to be disabled in the BIOS I was able to boot again!
By enabling every option one-by-one I was able to narrow the problem to the option "Execution Prevention" in tab Security -> Memory Protection.
As this basically disables DEP, this is not a lasting fix in my opinion, but at least it got me up and running again.
Lenovo, please fix this. I hope this added information helps

So here is a question...
Is it that this group of users are the only T450s users who have Execution Prevention turned on in our BIOS and it's a conflict between Windows & the EP, or is it a conflict between some other common piece of software/malware that we haev and the EP?
I'm thinking that given we reached the windows splash screen it should be a Windows component that is the conflict, and not some other 'well behaving' piece of software.
Just a thought - I guess that is probably up to the Lenovo Engineering team to figure out.
