BitLocker says I don’t have a TPM chip


I just purchased a dv6500 notebook direct from HP. Before I bought it, the sales guy on the phone assured me that this laptop included a TPM chip, and thus could run Bitlocker. I bought the system with Home Basic, and then installed a copy of Ultimate (which I bought from my university for half the price HP was charging to install it), and partitioned my drive accordingly. However, the bitlocker application says that I do not have a TPM chip.

After several calls to HP, most involving supervisors and managers, I was told by technical suppport that they had never heard of TPM or Bitlocker. Finally, I found someone who would tell me that “the hardware requirements for Bitlocker are met on your notebook”. He, another sales associate whom I called, both said that the TPM chip is installed on all dv6500 notebooks.

However, since I installed the copy of Ulimate myself after purchase, HP will not help resolve any issues that are within Vista Ultimate, nor will they provide any support for me. 

Thank you for any assistance you can provide,



First let me say that I’m NOT a fan of HP tech support… but that’s not going to help you.

In all liklihood, you do have a TPM chip. Try restarting your computer and entering the BIOS setup. TPM chips are almost always turned off in the BIOS by default, because most people don’t use them. So, turn it on, restart Vista, and see if BitLocker can see the TPM chip.

If BitLocker still can’t see the TPM chip, check the HP website for updated TPM drivers (which might be confusingly labelled as something about security).

I hope that helps, and good luck.

    How can I add more on send to when I right click?

    • Hi Milan,
      You can add more items to your send to menu by doing the following.
      1. Create shortcut to drive/folder.
      2. Copy shortcut to:
      XP – C:\Documents and Settings\USERNAME\SendTo\
      Vista/7 – C:\Users\USERNAME\AppData\Roaming\Microsoft\Windows\SendTo
      Hope this helps :)

    Go into group policy (gpedit.msc) Computer Configuration -> Administrative Templates -> Windows Components -> Bit Locker Drive encryption -> Advanced Startup Options. Open this option by double clicking it, ad then chose “Enable”. This will allow you to save the encryption key to a USB drive.
