LENOVO-TC-5M was what I used to mod my BIOS. The only certs I can find are: LENOVO LENOVO-CB-01 LENOVO-TC-2P LENOVO-TC-03 LENOVO-TP-79 Does it matter which one I use?/Does anyone have the LENOVO-TC-5M cert?
as long as you the lenovo slic to mod the bios any of those should work fine. imo use the standard lenovo one.
