After looking at your service manual and system specs, I do not believe your notebook has a TPM chip.
You can find out for sure by going to your control panel, click on Device Manager, then click on the System Devices option. Look for a device labeled Infineon Trusted Platform Module.
If that device is not listed, you don't have one.
According to this link you can use bitlocker without TPM.
