TPM and an HP ProBook 4540s

[ApolloAudio]

I have a new ProBook 4540s, with Win7 Enterprise installed. I need to encrypt using BitLocker, but the system cannot find TPM hardware, and the BIOS has no option to enable it. Spec sheets list that this system is TPM compatible, so I'm confused as to where I enable it. Any suggestions?

I have already set an admin password in the BIOS to "unlock" the areas that are inaccessible without setting one up, and TPM is still not an option.

Hi,

TPM is a hardware thing, it's a chip and software/firmware/microcode. Not just from BIOS. Do you have THIS CHIP on your machine ?

Regards.

According to the Spec sheets, it should. It's listed as standard equipment with HP DriveTools on all ProBooks.

Hi,

Here is its specs:

it clearly says:

Security management
Standard: HP ProtectTools

• HP Client Security (Windows 8 only)
• Drive Encryption for HP ProtectTools
• Credential Manager
• HP Security Manager
• HP Spare Key
• File Sanitizer for HP ProtectTools (Windows 7 only)
• Enhanced Pre-Boot Security
• HP Face Recognition
• Security Lock slot
• Optional: Security Lock
• Intel Anti-Theft Technology (requires Absolute Computrace subscription)
• HP Fingerprint reader
• Microsoft Security Essentials

No TPM, the Driver Tools and TPM is totally 2 different things. TPM needs a chip. Driver encryption can be software driven such as Guardian Edge on my work laptop.

Hope this makes sense.

TPM is a chip that is used for storing the encryption keys for machines that will use Bitlocker.

However, if your machine does not have one, that's not a problem, as you can also use a USB thumb drive to store the keys.  That's too bad you didn't get your questioned answered from before.

Those that are answering TPM questions should know the options involved instead of just posting the parts listing.

This one threw me for a loop too.  All our other ProBooks have TPM but the 4540s doesn't.

This should be a standard feature on all "probooks."
