What causes the Event ID 15 TPM error? 

Generally, the error appears if you have a problem with the TPM device. Some of the reasons for the error are: 

  • TPM fails to respond:  When Windows is trying to communicate or use the TPM device for functionalities that respond on TPM, including Bit Locker and Next Generation Credentials, and it fails to respond, it could cause the Event ID error.
  • TPM performing self-test – When TPM resumes from sleep, it performs a self-test before processing any commands. During self-testing, if Windows tries to retrieve a random number, but the command fails, then Windows will receive this error. If the command fails three consecutive times, the OS logs the event. Hence we see the error.
