TPM on HP 250 G4 running Windows 7 x64 Pro - Is it possible?

HP Recommended
HP 250 G4
Microsoft Windows 7 (64-bit)

Hello,

 

We are supplying a customer with a laptop whichrequires the following spec;

 

  • TPM
  • Windows 7 x64 Pro
  • Sub £500

Many of the laptops specify "Firmware TPM requires Windows 8.1 and Broadwell CPU (Intel Core i5-5200U, i3-5005U or Intel Pentium 3825U processors).". I have a hard time believing Windows 7 x64 Pro is not compatible with TPM and Bitlocker on these laptops. I have got the 250 G4 TPM working with Windows 10 x64 Pro. I'm hoping it is actually compatible with Windows 7 as well, otherwise HP are selling a laptop with a feature that cannot be used. 

 

Can anyone clarify this for me please? 

 

Many thanks,

Simon

Hi, Simon:

 

There is a patch from Microsoft to allow for TPM 2.0 to work on W7 64 bit.

 

But don't you need W7 Ultimate to use Bitlocker?

You can see that I solved this person's issue below who also has a 250 G4.

I uploaded the file for him, but it is the same one on the link I posted.

 

Here is a link to what the W7 versions supported...According to the list, Bitlocker is only supported on Ultimate and Enterprise.

Hi Paul,

 

Thanks for your prompt reply.

 

Yes, you are correct. It is only W7 Ultimate and Enterprise. I think I was getting mixed up with W10 Pro being compatible with Bitlocker. Not a problem though, we can supply a W7 Ultimate license within the price. That certainly sounds promising.

 

I guess my next questions are;

 

  1. Is there anywhere that states the 250 G4s are running TPM 2.0? The data spec sheets don't seem to state this.
  2. Do you know if the patch you posted is applicable to all 250 G4's with either Intel/AMD chipsets, or is it AMD chipsets only?

Thank you again for your time.

You're very welcome.

 

Unfortunately, I wouldn't know if every product number 250 G4 has one.

 

You would probably have to contact HP sales or technical support to get confirmation.

 

The fact that yours does, and the other guy's did, is encouraging.

 

The patch is applicable to the Intel ones for sure, and if a HP 255 G4 (AMD) after installing W7, has an unknown device with the hardware ID of ACPI\MSFT0101, then the patch should work for that platform too.

 

250 G4's are the Intel based notebooks, and the 255 G4's are the AMD based notebooks.

Congratulations!!!  What steps did you take to get bitlocker working on the HP 250 G4 Widnows 10 unit?
