TPM chip?

Does anyone know if the 2008 iMac 24" has a TPM chip? Windows/Boot Camp is telling me the computer has no TPM. If it does, where can I find a driver for this?
Thanks!

Dunno if anyone ever responded to you or if you got the info else where, however from what I know, macs do not have TPM chips inside. You will mostly find these chips in Business or Industrial class desktop/laptop hardware. TPM has not really taken off in the consumer world just yet.

  • How do I find out if my laptop has the TPM chip on the motherboard?

    Hi,
    Laptop model - HP Pavilion dv9260us.  Product ID - RP243UA#ABA  SR No - CNF7134YJK
    OS - Windows Vista Ultimate Build 6002.
    I downloaded and installed the Bitlocker from Windows Extras for Vista ultimate under Windows Update. I got a message stating:
    A TPM was not found.  A TPM is required to turn on Bitlocker.  If your computer has a TPM, then contact the computer manufacturer for Bitlocker-compatible BIOS.  Currently, I have BIOS version F.2E
    Thanks.

    Hi:
    I would not have any idea how you would go about getting a TPM chip added to the motherboard, or if it is even possible.
    I am not a PC repair tech or electronics technician by trade.
    If your work requires the need of a TPM chip, I would recommend you purchase an off lease or new HP business notebook, and make sure the model you want comes with one.
    I know the Elitebook notebook models do, and the old ncXXXX models do.
    Some of the Probook models have them too, but not all of them.

  • Kernel module for D30 TPM Chip Linux?

    Seems that Linux does not recognize the TPM chip. Could it be that there is no module for it in Linux Kernel? I Thought D30 supports RHEL6?
    Manufacturer: LENOVO
    Product Name: 422916G
    Version: ThinkStation D30
    BIOS Revision: 0.37

  • Script to locate if systems has a TPM chip and it's status if it does.

    I am looking for a script that would scan AD for a list of computers and then query them to see if they have a TPM chip and then what the status of each one is.
    I have been looking around and so far haven't come across one. Any help would be really appreciated for this scripting noob.
    Edited: I also have SCCM and ConfigureSoft's ECM in my company, so maybe those could be leveraged to do this but i haven't found the way to do it yet either.

    Hi,
    Here is a function I wrote to help identify the TPM and check its status.
    The problem is, most TPM's come from the fasctory turned OFF. If that is the case,
    Your computer will not know if it has one or not.
    Turning the TPM on requires at least one reboot and possibly two or three.
    I have a bunch of vbScripts I wrote that will check to see if the TPM is;
    1. Enabled
    2. Activated
    3. Owned
    Function ChkTPM {

  • Thinkcentr​e M82 TPM Chip.

    Hello All,
    Has anyone have any experience enabling the TPM Chip that is on M82 2929s? I need to encrypt a load of machines using bitlocker but when I go through the set, I get an error message that tells me there isn't a TPM chip availiable. The specs on the M82s I have say there should be a TPM, but even when I go into the BIOS I cannot find any mention of a TPM!
    Have I missed something? Any help would much most appreciated! 

    The specs on a GTX 970 are:
    145   Graphics Card Power (W)
    500   Minimum System Power Requirement (W)
    2x 6-pins   Supplementary power connectors
    Even with an upgraded power supply, the case doesn't have the air flow to cool a card like this.   In addition, the BIOS probably won't recognize and support this model of graphics card.   ThinkCentres are business class computers, if you're wanting a gaming computer worthy of a GTX 970, best to start with a computer designed for gaming. 

  • Yoga 2 TPM chip?

    thank you

    I'm trying to turn on bitlocker. Can someone confirm that the BIOS has TPM or not. My research tells me it does not but I'm looking for confirmation. I don't want to have to have a USB stick plugged in to boot. So bitlocker will not work? Thanks!

  • TPM chip and ESXi 5.5

    Hello,
    I have question about proper enabling TPM functionality in VMWare.
    I installed TPM chip in Cisco blade UCS B200-M3 and I enabled TXT and TPM functionality in BIOS according to Cisco user manual.
    Blade rebooted with no problems and bios does show TPM configured (attached screenshot).
    Unfortunately I can not figure out how to enabled TPM functionality in VMWare.
    The esxcli command shows lack of TPM:
    # esxcli hardware trustedboot get
       Drtm Enabled: false
       Tpm Present: false
    The query "QueryTpmAttestationReport" in webinterface of the ESXi and vCenter
    does not show any PCR entries (screenshot attached). In addition bios shows entry "TPM Owner status: unowned".
    I can not find any option/setting in vCenter or ESXi to manipulate with TPM functionality.
    I searched through KBs in Cisco and VMWare and I can not find any specific information about troubleshooting TPM in ESXi or vCenter. 
    I would appreciate some help in this matter.
    Thank you,
    Robert

    The minimum version, for both Windows 8 and 8.1, is ESXi 5.1
    To upgrade, you need to upgrade at least one of your hosts to ESXi 5.1. To manage that host with vCenter, you will need to upgrade vCenter to 5.1 as well, which will manage your ESXi 5.0 and 5.1 hosts. See the following link for interoperability: http://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php
    Here is the link to upgrade a host to ESXi 5.1:
    http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2032757
    Here is the link to upgrade from vCenter 5.0 to 5.1:
    http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2032283
    I strongly recommend you use the VMware Interoperability Guide, in case you have older ESXi hosts (i.e. 3.5) that will no longer be managed when you move to vCenter 5.1.
    Hope that helps.

  • TPM chip on a Kirabook

    Is there a TPM chip i the Kirabook? I do not see any options for enabling it and searching online has been fruitless. I use my machine for work and a TPM is pretty much a given to ensure this machine remains ultra portable instead of covered in dongles just to work.

    You may want to contact KIRA Platinum Service & Support's customer support by phone, text or live chat.

  • Testing WMI for TPM chip

    Win 7 Ts with a group to pre-provision Bitlocker (SCCM 2012 SP1)
    The group has a condition to run only if "select * from win32_TPM where IsEnabled Initialvalue="False"
    This works fine on HP laptops but testing a Dell Latitude it skips past
    Check wbemtest on the laptop I see the class with a value of <null>
    so I 've added an extra condition if any of the conditions are true to include initialvalue="<null>"
    still skips past the group - I also tried just "null" bit same again
    any thoughts ?
    Ian Burnell, London (UK)

    Thanks for replying Niall. Yes I'm following your article and it works great. It is simply the TS test I need to determine whether to run or skip the "pre-provision Bitlocker" group.
    My current test for the group is to test for Win32_tpm where isenabledinitialvalue="false". There is a mix of HP and Dell kit (all bare-metal out of box builds). For HP kit this test works fine i.e. the group runs but for Dell kit it skips the group therefore
    evaluating the condition to be false - that's what I need to sort out. When you look in Bios the chip is there but TPM is not enabled or activated hence the steps using the CCTK (or HP Repset) but its just getting the right condition test so that it will run
    the group correctly

  • Bitlocker with TPM and PIN testing?

    Good day all,
    We are about to deploy 10 Surface Pro 3's running Windows 8.1 Enterprise x64. We have enabled the TPM, enabled "Allow Enhanced PINS for Startup", "Pre-boot Keyboard" and turned on Bitlocker through the gui which recommended setting
    a PIN which I did.
    Everything seems to work as it should, how can I be convinced TPM and PIN are working together? I seem to be able to punch into Bitlocker many bad passwords without warning or asking me to reboot which is does for all other laptops without tpm.
    1. How many bad password attempts do I get with TPM by default before lockout?
    2. Where is my *.tpm recovery key?
    3. Why when the TPM locks out can I still gain entry by typing in the Bitlocker PIN (not recovery password)
    4. I want TPM to lockout after 5 incorrect attempts.
    To test the TPM working I disabled the TPM in the BIOS and on next reboot Bitlocker asked for the Recovery Password which to me proves Bitlocker private encryption keys are safely held in the TPM. Is this safe to presume TPM is working?
    here is the output from manage-bde and get-tpm status
       Size:                 59.11 GB
        BitLocker Version:    2.0

    Hi Paddy,
    "1. How many bad password attempts do I get with TPM by default before lockout?"
    It depends on the the TPM chips.
    "Some TPM chips may not store failed attempts over time. Other TPM chips may store every failed attempt indefinitely. Therefore, some users may experience increasingly longer delays when they mistype an authorization value that is sent to the TPM"
    "4.I want TPM to lockout after 5 incorrect attempts."
    We can set the group policy "Standard User Individual Lockout Threshold " in this path (Check the detailed information of this policy):
    Computer Configuration\Administrative Templates\System\Trusted Platform Module Services\
    Here is a link for reference("About TPM lockout" part and "Use Group Policy to manage TPM lockout settings"part ):
    Manage TPM Lockout
    https://technet.microsoft.com/en-us/library/dn466535.aspx
    "2. Where is my *.tpm recovery key?"
    When we set owner of the TPM ,we will be given a chance to save the TPM passowrd .
    And when the BitLocker recovery key is saved to a file, BitLocker also saves a TPM owner password file (.tpm) with the TPM owner password hash value.We also can save them to the AD (Check the group policy in the same path as before). Have you tried to save
    the recovery keys to a external media ?
    Here are links for reference:
    Reset the TPM Lockout (Check the first part)

    "3. Why when the TPM locks out can I still gain entry by typing in the Bitlocker PIN (not recovery password)"
    When the TPM is locked out, it is also possible that the user will enter the correct PIN, but the TPM will respond as if the incorrect PIN was entered for a period of time.
    Check the "When should I reset the TPM lockout" part .
    Reset the TPM Lockout
    https://technet.microsoft.com/en-us/library/dd851452.aspx?f=255&MSPPError=-2147217396
    " Is this safe to presume TPM is working?"
    From the output of the command line ,we can get the information that the TPM is working .It is not recommended to disable the TPM when the data is encrypted with TPM .
