ProBook 4520s

Is there a motherboard I can get for my ProBook 4520s that supports TPM?

According to the service manual the model series did not come with the TPM option.

If you were wanting to know this in order to upgrade to W11, your notebook does not meet other of Microsoft's minimum W11 hardware requirements such as having an Intel 8th generation core processor and supporting secure boot.

If you are interested in installing W11 on your PC as is, watch this video:

Download the W23H2 ISO file and use that (3rd option).

24H2 hasn't been released to the public yet. and if you don't have a W11 PC, you can't get the 24H2 Beta version.

Paul - Thanks for the guidance in upgrading the OS.  I didn't think I would get past the secure boot or TPM with the current motherboard.  I will be upgrading the memory, processor and HDD to a SSD.  Once that's done I'll go to Windows 11 per your suggestions.

You're very welcome.

Starting with W11 24H2, Microsoft upped the processor requirements.

In order to install W11 24H2 the PC's processor must support SSE 4.2 & POPCNT.

The bottom line is no Intel processor older than an Intel 1st generation core processor will work with W11 24H2, so your notebook just made the cutoff.

Otherwise, you would have to remain on W11 23H2.

Thanks again Paul.  I'll check my other PCs too.  Your attention to this matter really was helpful.

Anytime.

Glad to have been of assistance.
