Before we fix the problem, we must understand the hardware. The Dell Vostro 5568 (circa 2016-2017) does have a discrete TPM 2.0 chip soldered to the motherboard in all configurations. Instead, it relies on Intel Platform Trust Technology (PTT) – a firmware-based TPM embedded within the Intel Chipset (usually 6th or 7th Gen Intel Core).
The Vostro 5568 uses Intel Chipsets. If the Intel Management Engine Interface (IMEI) driver is corrupt, the TPM will not be detected.
Sometimes the issue lies within Windows' communication with the hardware.
Locate the latest (.exe) and download it.
Getting Windows to say “TPM is ready for use” is one thing. Achieving extra quality means ensuring it stays reliable. Here is the pro checklist for Vostro 5568 owners:
The Vostro 5568 uses a coin-cell battery (CR2032) to retain BIOS settings. A weak battery can cause device detection errors during POST.
Select the option to or Load Optimal Defaults , then apply and restart. 3. Re-Enable TPM Security in System Setup
: Invalid system data states can hide peripheral controllers, including security hardware, from the BIOS menu. Step-by-Step Fixes for the Dell Vostro 5568 1. Hard Power Drain and Static Discharge
Temporarily change the from UEFI to Legacy . Save changes and exit.
Once inside the BIOS (version 1.8.0 or later required), navigate away from the default "Overview" screen.
: Disconnect the internal battery (if comfortable opening the case) and press/hold the Power Button for 30 seconds.
If you updated the BIOS and performed a hard reset but the TPM menu option is entirely gone, your motherboard might have experienced a localized hardware failure, or you are using a motherboard variant manufactured for regions where TPM tech is legally restricted. If it worked previously, the security chip has likely suffered a permanent hardware fault, requiring a motherboard replacement. Downgrading/Upgrading TPM Firmware
