Win 7 64 bit + Intel P55 Chipset (HP dv7t laptop) + iTunes/iPhone = Sync Failure

    General discussion

  • Got a new laptop running Win 7 64 bit and due to what appears to be the somewhat famous P55 chipset incompatibility issues I cannot sync my iPhone with it.  I think (although I could be wrong) the solution lies with a BIOS or Chipset Driver update from the manufacturer (HP), but I seem to have reached a dead end there, so I thought I would take a chance and see if anyone here had any suggestions.


    Here are the details in the form of one of my latest correspondences with HP:

    On my dv7t-3000 CTO Notebook  with Intel(R) Core(TM) i7-720QM Processor I have installed the latest versions of Apple iTunes and Microsoft Windows 7 64 bit.  But I am unable to sync my iPhone. 


    This machine has the following chipset: Intel(R) PM55 Express Chipset


    This is a known incompatibility problem with the P55 chipset and Windows 7 64 bit with respect to the USB ports.  So far the fix for this has been a BIOS update from the respective manufacturers of the motherboards affected.


    Here is a thread from the HP forum where many users have posted the same problem:


    A good summary of the P55 chipset compatibility issue can be found here:


    This is one of many Apple Forum threads discussing the issue is here.  It starts out with desktop modders but around page 13 you will see more and more HP laptop owners start to chime in with their woes.:


    For people who build their own desktop machines, motherboard manufacturers like Gigabyte and ASUS have already released BIOS updates to fix this problem


    But in the case of owners of HP laptops, it is up to you (HP), as the motherboard vendor to provide a BIOS update to fix this problem.  I even contacted Intel, who then directed me to contact you (HP) the PC manufacturer:

    Hello Seth,

    Thank you for contacting Intel Customer Support.

    I understand you cannot synchronize your iPhone* and your computer system.

    We are aware of this situation with the Intel(R) P55 Express Chipset. Intel recommends that you contact your system maker or motherboard manufacturer for the latest bios and driver updates, as this does not depend on the system directly but on the motherboard itself.

    Please do not hesitate to contact us again if you need further assistance.

    So, PLEASE escalate this to the appropriate support level so that your personnel can interface with Intel so as to make this happen.  If you do not fix this then every iPhone user who buys a new dvXt or Envy laptop will be affected.


    I have tried everything…this list is probably not complete….



    -          BIOS update is not available (is currently version F.04)

    -          Chipset drivers updated to latest (

    -          Tried iTunes 9 running Win XP sp3 mode

    -          Tried iTunes 8.2 running Win XP sp3 mode

    -          Tried Install iTunes 32, then 64 on top of it

    -          Tried iTunes 32 bit (will not you use it)

    -          Tried using ExpressCard USB card instead of onboard USB ports

    -          Tried iTunes inside Windows XP Mode (Virtual Machine)
