Hi,We've recently had to send a laptop away for repair and it has come back to us with a new motherboard. The issue we have is that the laptop was BitLocker'd with TPM and new TPM chip won't authenticate against the BitLocker. We can bypass this using the key (which we have on a USB stick) but we need someway to assign the new TPM chip to the existing installation of BitLocker.erm...help?!

Hi, can you disable bitlocker by following the steps in the article: http://windowshelp.microsoft.com/Windows/en-US/help/17372e1b-429b-41ea-b93d-11d29ec679721033.mspx Sean Zhu - MSFT
