Issues in activating TPM on an ASUS laptop following a motherboard repair
Issues in activating TPM on an ASUS laptop following a motherboard repair
I'm facing difficulties turning on TPM 2.0 on my ASUS laptop, which is blocking me from playing Valorant. The error message appears when I launch the game:
"Compatible TPM cannot be found."
In my UEFI settings, there’s no option for TPM; the only available choices are Secure Boot enable/disable.
What I’ve done:
- Restored Secure Boot keys to factory defaults.
- Reset the BIOS.
- Reflashed the BIOS with the latest version.
- Performed a CMOS reset.
None fixed the problem.
Background info:
My laptop originally had a TPM chip, and I installed Windows 11 without any TPM-related steps. Later, I switched back to Windows 10 for personal reasons. Asus claims compatibility with Windows 11.
About a year ago, I accidentally damaged my laptop’s screen. I tried connecting an internal LCD from another device, but it caused further damage. The repair shop returned it after two months, saying they couldn’t find a compatible 144Hz display. At that time, I didn’t ask about the specific parts they repaired or replaced.
Now I’m wondering if they might have disabled TPM and/or Intel ME to make the system work with the new parts.
Additional details:
- My processor is an Intel i7-9750H.
- The UEFI settings show Intel ME as disabled, even though the product page says it supports it.
- HWiNFO reports Intel Virtualization Technology (VT-x) as disabled, while CPU-Z lists it as disabled.
Questions:
- Is TPM connected to Intel SGX or Intel ME?
- Could the repair shop have turned off TPM, Intel ME, or replaced parts that affect these features?
- Might the shop have disabled Intel ME, Intel SGX, and TPM together because of a faulty PCH replacement?
Any guidance would be very helpful.
My setup:
Model: ASUS ROG Zephyrus M GU502GU
Edition: Windows 10 Pro
Version: 22H2
Installed on: 15-09-2024
OS build: 19045.4780
Experience: Windows Feature Experience Pack 1000.19060.1000.0
CPU: i7 9750H
GPU: GTX 1660Ti
TPM is located in the CPU but needs to be turned on or off via the BIOS.
A repair shop might have updated the BIOS without enabling TPM by default, which is likely an older version. You can check the BIOS version in the MB tab and compare it with the one available on the manufacturer's website. BIOS/UEFI can be accessed and modified using special software.
They may have just installed Windows.
In Device Manager, TPM should appear under Security devices.
As mentioned in my previous message, there isn't an option for TPM in the UEFI firmware settings of my laptop. As discussed earlier, I reinstalled the most recent BIOS from ASUS's support site for my device. No, I had kept the SSD with me before taking it to be repaired. There is no "Security Devices" entry in Device Manager.
