Do you want to Upgrade your Dell Inspiron Laptop to Windows 11 But, you face the message ” This PC can’t run Windows 11″? TPM 2.0 and Secure Boot are the main causes of this problem. Don’t worry if you don’t know how to fix this mistake or enable TPM and Secure Boot from the BIOS on your Dell laptops. In this Guide, You’ll Learn How to Enable TPM and Secure Boot in BIOS on Dell Inspiron Windows 11 and 10.
TPM Chip
A Trusted Platform Module (TPM) is a little chip on your computer’s motherboard that handles security-related tasks at the hardware level. It’s essentially a tamper-resistant crypto-processor that can generate encryption keys and provide a mix of software and hardware-based authentication.
In most modern off-the-shelf computers, a separate TPM chip is soldered to the motherboard. If you’re building your own PC, you can buy one as an add-on module for any motherboard that supports it. As we’ll see later, though, not all motherboards accept TPM chips or have the essential connection.
Difference Between TPM 1.2 & TPM 2.0
According to Microsoft, the TPM 1.2 standard only allows for the use of RSA and the SHA-1 hashing method. The document continues, “TPM 2.0 delivers additional crypto agility by being more adaptive with respect to cryptographic algorithms.” TPM 2.0 introduces new algorithms that can increase drive signature and key generation performance.”
TPM 2.0 technology, simply put, is newer than TPM 1.2, which has been in use since 2011. Its encryption is more powerful and secure, and it has a superior ability to accommodate newer algorithms. And, as with most technological advancements, the newer the better.

Enable TPM (PTT) in BIOS on Dell
Some Dell systems lack a TPM (Trusted Platform Module) module, instead of relying on PTT (Platform Trust Technology). PTT is a lower-cost alternative to TPM that performs the same functions. From an OS standpoint, there isn’t much of a difference between TPM and PTT in terms of how they interact with bit locker.
