My keyboard suddenly stopped working last night, so I had to restart my computer. Afterward, I checked the system logs and found several similar errors. One was marked critical, although it appeared during the reboot. The main message says the Trusted Platform Module (TPM) encountered a non-recoverable hardware error, which prevents TPM-dependent services such as encryption from working. Should I be concerned, and what troubleshooting steps should I try?

The TPM message may not be the original cause; it could be a consequence of another hardware or system problem. Since you’re seeing multiple errors, test the RAM and check the health of your storage drives. Also confirm whether the keyboard works normally now and look for newer errors that occur when the problem happens again.
This error is related to the TPM, not necessarily the keyboard. A TPM failure can affect features such as BitLocker or other security functions, but switching from Windows to Ubuntu would not fix a failing hardware component. First determine whether the issue is a temporary firmware problem or an actual hardware fault.
If the computer uses BitLocker or device encryption, make sure you have the recovery key and a backup before changing TPM or Secure Boot settings. You can check for firmware and BIOS updates from the computer manufacturer, run the manufacturer’s hardware diagnostics, and contact them if the TPM continues to report non-recoverable errors. Avoid disabling security features as a first step, since that can make encrypted data harder to access.
