This system supports Intel PTT -- which is TPM, assuming it was not originally sold in a part of the world where TPMs are illegal (Russia, China, much of the middle East).

Look in Setup for a PTT setting.

Good Day thanks for the reply but how do I check for PTT if you can please guide me i will appreciate it very much 

Welcome to the Dell Community @Sundrap 

Did you look under "Security" in the BIOS for the TPM settings???

TPM 1.2/2.0 Security Allows you to enable the Trusted Platform Module (TPM) during POST. The options are:

• TPM On (selected by default)
• Clear (option is disabled)
• PPI Bypass for Enabled Commands (selected by default)
• PPI Bypass for Disabled Commands
• Disabled
• Enabled
• Attestation enable (selected by default)
• Key storage enable (selected by default)
• SHA-256 (selected by default)

I have tried all options but no TMP feature in BIOS under security

as per the ship spec

I do not have tmp in my Bios setting

@Sundrap 

All I could find in my warehouse was a Precision 5520.

You would think your model should have it also???

Sorry I could not find your model.

Thanks for you help I am going to buy a Mac laptop as Dell order showed that TMP was part of the original spec which I believe was not bad service 

If so, note that if your plan is to run Windows on the Macbook, Windows 11 will not be supported -- Mac systems do not support TPM 2.0.

Also, that "China" label reference in your list is curious -- if the Dell system was originally sold in the Chinese market, it would explain why there's no TPM;  in China, TPM technology is illegal.

Information about laptop is on the Dell site in South Africa

Sorry this laptop was purchases in South Africa from Dell and not China market
