Help! I recently disabled tpm 2.0 on my acer nitro 5

lhxrh · May 2022

I recently disabled tpm 2.0 on my acer nitro 5 and now I can't find the option to turn it back on. It does not give the option that says tpm enable or disable under restore secure boot to factory default. And I have tpm because it showed me in device manager however it is not connected anymore. I need help please.

What is the exact model? Example AN515-55-58VH. Have you already created a password in setsupervisorpassword? Can you send some pics of all the bios tabs?

My model is AN515-56, I recently accidentally TPM 2.0 in BIOS after upgrading to Windows 11. Now some softwares can’t run because it need TPM 2.0 enabled. But after disabling it, it can’t be detected anymore, in BIOS the whole TPM option was just gone. Should I go back to windows 10 and do you think that then will be possible to re enable TPM 2.0. There has to be some way to enable it again after you disable it. If you know what to do can you please help me and provide specific instructions on what to do because I did not mean to disable TPM 2.0 and I need it re enable. I am scared that if I go back to Windows 10 and I still can’t figure out how to enable TPM 2.0 I won’t be able to upgrade to Windows 11 again. What should I do? Should I email Acer?

That is the photo of my security BIOS tab. As you can see I have supervisor password enabled. Yet after I disabled TPM 2.0. The whole option just somewhat disappeared. I tried to do as much research as I possibly could but nothing is found and I don’t know what to do to enable it again. I am scared to do anything more because I might do something wrong which could lead to worse situations. Any help would be appreciated.

Try resetting the battery: disable fast startup in power options, turn off the computer, unplug the power adapter, press the power button for thirty seconds and leave the computer off for half an hour.

Then check if the tpm reappears in the bios. If tpm still doesn't show up, check the bios version:

I will try the steps later and report if it works or not. Right now my BIOS version is the newest one (1.09) I had 1.06 before but it didn’t work so I upgraded and still did nothing.
