How to Reset your TPM without Losing Data
Resetting the TPM is not the same as clearing the TPM. During a TPM reset the system will attempt to redetect the TPM and preserve the data held within.
- For Portable systems:
- Remove the AC adapter, power off the system, and disconnect any USB devices
- Power the system on and press F2 to enter System Setup BIOS
- Is TPM available under Security? If yes, no further steps are required
- If TPM is not present, power system off and disconnect main system battery
- Drain flea power by holding the system power button for over 60 seconds
- Reconnect the main system battery, AC adapter, and power system on
- For Dekstop / All in One systems:
- Power the system down and unplug the Power cord from the back of the PC
- Drain the flea power by holding down the power button for over 60 seconds
- Re-Plug the Power cord to the back of the PC and power the system on
