Lenovo B590 BIOS & Windows activation

[ChickenDhansak]

Afternoon all

We have a solitary Lenovo B590 laptop that I've been given to sort out. It has a Win8 sticker on it and I think long ago it was re-imaged with our standard college Win 7 Pro image & then stuck in a cupboard.

 

However, the 'windows may not be genuine' message is on the screen and long story short I re-imaged it but I cannot activate it using our KMS. Having trawled the Lenovo website it appears to be an issue with a BIOS setting where originally the laptop came to us with Win8 on it. As far as I can make out the BIOS setting Preinstalled OS License is set to 'Windows 8' & from the article text below this is preventing us activating Win7. We've never had this issue with other laptops including newer Lenovos. Can anyone offer any assistance in how we can activate Win 7 Pro? (we do not have any Win7 or 8 media - this is all controlled by our parent college and we are not upgrading to Win 10 until after Xmas).

Error Code: 0xc004f035 - The Software Licensing Service reported that the computer could not be activated with a Volume license product key. Volume licensed systems require upgrading from a qualified operating system. Please contact your system administrator or use a different type of key.

This behavior occurs when the following conditions are true:

• You are using the Key Management Service (KMS) to perform activation.
  
• The computer uses an ACPI_SLIC table in the computer BIOS program.
  

Note An ACPI_SLIC table is used by an Advanced Configuration and Power Interface (ACPI)-compliant BIOS program to store Software Licensing description information.

Funnily enough, our B590s also do this. I never managed to do it with KMS though, I just use our allocation of MAK keys to activate these. Have you tried playing some some of the BIOS settings related to the OS type?

Oh I've spent the last 2 hours twiddling with the BIOS to no effect.

Thanks for the replies. I'm guessing I'll have to do the same

KMS requires the machine have a SLIC table in the BIOS. Download the SLIC toolkit and take a look.

Some Windows 8 machines have the Windows 7 SLIC tables and some don't. It depends if the machine was ever designed to support downgrade rights. If the machine did support downgrade rights, you would have an SLIC. You want to check your SLIC tables and see, usually it should be SLIC 2.0 or 2.1 if it supports it.
