According to Dell's tech support forums, this TPM module is designed  
to disable parts of your computer such as the NIC if it doesn't find  
the right keys or whatever it is supposed to contain.  Trying to  
reinstall the TPM drivers under Windows isn't enough to reset the TPM  
module to a sane state, reportedly.

In other words, if it screws up, your machine becomes hosed.  Welcome  
to trusted computing.

Supposedly you need to RMA your laptop.  Or, better yet, replace it  
with something else that doesn't contain defective hardware which  
locks the owner out of their own machine....
