    Hey everyone, just wanted to share my experience with this conversion.

    I had an 8460p that I wanted native USB 3.0 for macOS High Sierra and the biometric fingerprint reader, so I swapped out the board and other things so it's essentially an 8470p in an 8460p shell. Let me tell you...it was NOT a direct swap. You will NEED to buy a few extra things to get the swap to work correctly.

    My new build is running as follows:

    HP EliteBook 8470p
    Intel Core i7-3820QM Quad Core CPU w/8MB L3 Cache 2.7Ghz-3.6Ghz (45W TDP)
    16GB PNY DDR3 1600Mhz CL-11 RAM
    2x 250GB Samsung Evo SATA III 2.5" drives (one in main caddy bay for Windows 10, second in Optical drive via ODD Drive caddy for macOS)
    Broadcom BCM94352HMB Wireless-AC Mini PCI-E card (AC runs @ 867Mbps... BT will not work from the card since the machine already has built in adapter)
    1600x900 HD+ 14" display (using available HD+ cable *for* the 8470p...standard cable for the 8470p or the HD+ cable from the 8460p will NOT work)

    I had to purchase other parts to complete the swap. you would think that they would use the same layout between boards if they are using the same chassis...NOPE. What a pleasant surprise to me haha. Here are the things I had to swap to get it to work.:

    Swapped the mainboard from the 8460p to 8470p. I used the Intel version (non AMD GPU version) of the board due to concerns of heat. I will be using the i7-3820QM so that sucker will generate a lot of heat. Don't need more coming from the GPU. I can always use an eGPU to get more horsepower, but this laptop is not purposed for gaming.

    Swapped the original top bezel to get the ability to use the fingerprint reader. Doing this made me realize that the express card adapter from the 8460p is NOT compatible with the 8470P board. Which is why...

    Swapped the express card card to get the touchpad, express card and the Power/HDD/AC/Wi-Fi LED's to work.

    Swapped the HD+ cable from the 8460p version to the 8470p version. They are NOT the same apparently.

    Swapped the old Broadcom BCM43224HMS Wi-Fi 801.11n wireless card (The only one compatible with macOS that is not blacklisted by the BIOS) to the BCM94352HMB 802.11AC version. The 8460p has a bios whitelist for Wireless cards, and the 8470p does not. (Good thing to have on macOS.)

    I have Windows 10 and macOS High Sierra 10.13.3 running on dual boot perfectly fine. it was not an easy task but I don't see any other way of upgrading it unless I get larger capacity SSD's. It runs like a champ.

    I still have some leftover parts from the 8460p, like the CPU, ram and mainboard/others. I would sell it on NBR, but I need to reach 100 post. Let me know if you have any questions, or if you would like some pictures, hope this helps.

    Well done! I've just done a 6460b to 8460w switch. Fairly straightforward but there's no iso smart card slot on the 6460b lower case. If the mainboards are the same size, would it be daft to move now from 8460 to 8470? Thanks...
