Symptoms
Dell XPS 13 (9343) users may report they do not have the option to enable Trusted Platform Module (TPM) in the system BIOS setup menu.
The default configuration for trust technology is Intel Platform Trust Technology (PTT).
Cause
Note: If an Administrator Password is set in the BIOS, then access to the Administrator Password will be required to change the PTT and TPM settings.
Note: PTT or TPM can only be enabled individually, both cannot be enabled at the same time.
Resolution
To enable the discrete Trusted Platform Technology (TPM) chip:
Disable PTT in the BIOS menu under security settingsEnable TPM.
Note: Only systems equipped with the following Intel processors support TPM 1.2 I5-5300U or I7-5600U.
The XPS 13 (9343) systems do not support TPM on the following system Intel Processor configurations: I3-5010U, I5-5200U, or I7-5500U.
Another way to verify if the system motherboard supports onboard TPM1.2, is by pressing F12 during POST, if Intel® Management Engine BIOS Extension (MEBX) appears, the system motherboard supports TPM.
