ThinkPad T470 NM-A931 TPM dont recognize

[novator2007]

Hi All,

I got two T470 with faulty TPM

All work fine,except wake up from sleep.
Its not possible to start-up from sleep mode(open a lid by sleep active),got beeps error 0285

/There is no such option in Bios - Security Chip
/In Windows TPM not recognize
/Lenovo TPM Firmware Utility cant find a TPM(TPM Manufact. Unknow,Ver. 0.0)

If I correct understand,TPM is U39 Chip,ST33HTPH2E32
Its possble to swap it from spare Motherboard?

I have set a Supervisor pass and remove it with Util. from this forum - still nothing.


Maybe someone have expierence with such issue,please advice me..
