What you need

This teardown is not a repair guide. To repair your HP Z1, use our service manual.

  1. HP Z1 Teardown, HP Z1 Teardown: step 1, image 1 of 1
    • Here it is, the HP Z1 workstation. Collapsed down, the Z1 folds flat for easy-to-access component repairs.

    • Under the hood the Z1 houses:

    • Dual-core Intel® Core™ i3-2120 Processor

    • 27" 2560x1440 pixel, diagonal LED-backlit IPS display

    • Four memory slots for up to 32 GB DDR3 RAM

    • SATA 7200 RPM, 500 GB Hard Drive

    • An internal USB port

  2. HP Z1 Teardown: step 2, image 1 of 1
    • We mistook this big ol' green button in the center for the power button.

    • We were wrong.

    • This button actually activates the "raising" procedure, that is, if you don't want to use the Z1 as a non-touchscreen, 40 lb tablet.

  3. HP Z1 Teardown: step 3, image 1 of 2 HP Z1 Teardown: step 3, image 2 of 2
    • Although the Z1 bears a strong resemblance to a certain group of molluscs, it is considerably easier to open. We have yet to determine which tastes better.

    • Designed like a briefcase, all you have to do to open this device is release the thumb tabs.

  4. HP Z1 Teardown: step 4, image 1 of 1
    • Right under the hood of the Z1 is a handy diagram of all the components that are easy to replace.

    • Rather than a "diagram" we like to think of it more as a treasure map, leading us to user-serviceable booty.

  5. HP Z1 Teardown: step 5, image 1 of 3 HP Z1 Teardown: step 5, image 2 of 3 HP Z1 Teardown: step 5, image 3 of 3
    • All the major components on the Z1 have awesome release tabs -- no screwdriver required!

    • The hard drive bracket, capable of holding either a single 3.5" HDD or two 2.5" drives, bears a striking resemblance to a picnic basket.

    • Simple pins hold the 3.5" HDD in the bracket, eliminating the need for any kind of screwdriver.

  6. HP Z1 Teardown: step 6, image 1 of 2 HP Z1 Teardown: step 6, image 2 of 2
    • We are big fans of this computer. Or, we are at least fans of the fans inside.

    • The Delta Electronics KUC1012D 12V fan inside this enclosure appears to have a unique form factor, which means that acquiring replacement parts may be difficult.

  7. HP Z1 Teardown: step 7, image 1 of 3 HP Z1 Teardown: step 7, image 2 of 3 HP Z1 Teardown: step 7, image 3 of 3
    • Disconnecting the optical drive is only a matter of pulling out the SATA cable.

    • With one of iFixit's optical bay hard drive enclosures, it might be possible to put yet another hard drive inside the Z1.

    • This, of course, would mean a loss of Blu-ray capabilities, but with one of iFixit's hard drives installed, you can fit up to 50 HD movies inside the computer!

    • Green means go as the optical drive bracket speeds out of the Z1.

  8. HP Z1 Teardown: step 8, image 1 of 2 HP Z1 Teardown: step 8, image 2 of 2
    • The RAM replacement requires flexing a couple of fingers.

    • We would praise the Z1 for having easy-to-remove RAM modules, but then we remembered that most computers have easy-to-remove RAM modules.

    • The Z1 is capable of supporting up to 32 GB of DDR3 RAM. If you have to ask why you need 32 GB, then you clearly don't need it.

  9. HP Z1 Teardown: step 9, image 1 of 2 HP Z1 Teardown: step 9, image 2 of 2
    • Next out is the grab-and-go power supply — 400 watts of "that was easy."

    • We're not nearly as worried about zapping ourselves on this power supply as we are with other, more naked versions.

    • Hopefully, the ease of replacement of the power supply does not fortell an ease of failure.

  10. HP Z1 Teardown: step 10, image 1 of 2 HP Z1 Teardown: step 10, image 2 of 2
    • What's under the big black casing? Nothing, at least in our $2,000 "cheapo" machine.

    • If you shell out a few more clams for your Z1, you'll find a fancy schmancy NVIDIA Quadro graphics card here, as seen by HP's artistic rendering in the second image.

  11. HP Z1 Teardown: step 11, image 1 of 2 HP Z1 Teardown: step 11, image 2 of 2
    • The internal USB is a great place to hide the wireless mouse dongle.

    • We would like to take a second to reflect on how awesome this is. Imagine being able to plug in that annoying wireless dongle and never think about it again. Incredible!

  12. HP Z1 Teardown: step 12, image 1 of 1
    • Finally! Our first screws. We were beginning to worry there would be no use for our 54 Bit Driver Kit.

    • But even with pesky Torx T15 screws, removing the fans and heatsink from the top of the CPU is super-simple.

  13. HP Z1 Teardown: step 13, image 1 of 3 HP Z1 Teardown: step 13, image 2 of 3 HP Z1 Teardown: step 13, image 3 of 3
    • This is almost too easy! A simple flip of a lever and the Intel processor practically jumps off the motherboard.

    • These days we mostly encounter soldered-on CPUs on laptops and smartphones, so it's a bit refreshing to touch and feel a nice hunk of CPU silicon in one's hand. Even though this machine is nothing like the PC beige-boxes some of us built back in the day, there's something comforting about holding a can-be-upgraded CPU and inspecting it up close.

    • Fake rumor confirmed: our Z1 did, in fact, come with an Intel Core i3 2120 processor, running at 3.30 GHz.

  14. HP Z1 Teardown: step 14, image 1 of 1
    • According to the Z1 treasure map, this little button is for resetting the CMOS. No more jumpers to short out. Cool.

    • This connector is where the power button plugs into the motherboard.

    • And, according to the same treasure map, this connector allows you to plug in a second internal USB port, should you need another one inside the device.

  15. HP Z1 Teardown: step 15, image 1 of 1
    • The left speaker assembly is next to go.

    • A twist of the screwdriver and the Z1 goes back to old-school mono.

  16. HP Z1 Teardown: step 16, image 1 of 3 HP Z1 Teardown: step 16, image 2 of 3 HP Z1 Teardown: step 16, image 3 of 3
    • Removing the screws around the internal USB port frees the rear I/O board, on which we found:

    • Display In/Out

    • Ethernet Port

    • S/PDIF

    • Four USB 2.0

    • Audio Ports and Subwoofer

  17. HP Z1 Teardown: step 17, image 1 of 1
    • Round two of speaker removal is no sweat for our screwdriver.

    • We're going to guess that removing the speakers probably ruins the nicely engineered SRS Premium Sound.

  18. HP Z1 Teardown: step 18, image 1 of 2 HP Z1 Teardown: step 18, image 2 of 2
    • We're getting down to some serious deconstruction now. A few SATA connectors come out and the hard drive bracket is free.

    • These SATA cables connect the single or double hard drives to the motherboard.

    • Next up is the hard drive thermal sensor, which doesn't put up much of a fight.

    • Rather than taking Apple's approach, who changed their SATA connectors to a proprietary 7-pin design and embedded the thermal sensor inside the hard drive, HP is sticking with an upgrade-friendly design with standard SATA sockets and a thermal sensor that's mounted on the computer's internal frame.

  19. HP Z1 Teardown: step 19, image 1 of 2 HP Z1 Teardown: step 19, image 2 of 2
    • Next up: the side I/O board. This board is home to:

    • 4-in-1 media card reader

    • Firewire port

    • Two blue USB 3.0 ports

    • Headphone / mic ports

  20. HP Z1 Teardown: step 20, image 1 of 3 HP Z1 Teardown: step 20, image 2 of 3 HP Z1 Teardown: step 20, image 3 of 3
    • Just a couple more connectors, and the motherboard comes out.

    • But before we can take out the mobo, we've got to remove Intel's 6230 Bluetooth/WiFi card, which is held in place by two T6 Torx screws.

    • Attached to the power supply by an ATX connector, the motherboard is easier to remove than most logic boards.

  21. HP Z1 Teardown: step 21, image 1 of 3 HP Z1 Teardown: step 21, image 2 of 3 HP Z1 Teardown: step 21, image 3 of 3
    • So that's it for the bottom half of the computer. Now for the heavyweight LCD and glass.

    • Removing some conveniently-placed T15 screws is all it takes to remove the LCD and glass from the rest of the machine.

    • Despite the pile of screws left on the bench, we are relieved at the absence of our nemesis, adhesive, in HP's design.

    • One also has to remove about a dozen more screws to separate the glass and LCD, but hey -- they're the same-sized T15 screws, and the glass comes right off once the screws are removed! It's about as simple of a construction as it can get for a component that's this hefty.

  22. HP Z1 Teardown: step 22, image 1 of 1
    • We told HP that we were hosting a party, so they brought the chips:

    • Intel Core i3-2120 Processor with Intel HD Graphics 2000

    • Intel BD82C206 Platform Controller Hub

    • ON NCP6151 CPU & GPU Controller

    • Texas Instruments TUSB7320 SuperSpeed USB xHCI Host Controller

    • IDT 92HD91B Audio Codec

    • Texas Instruments DRV604 Line Driver & Headphone Amp

    • MPS MP3399 LED Drivers

  23. HP Z1 Teardown: step 23, image 1 of 2 HP Z1 Teardown: step 23, image 2 of 2
    • We're going to have to buy some more guacamole to go with all these chips:

    • Parade PS8321 DisplayPort Source 2:1 Multiplexers

    • Alpha & Omega AOZ5006Q1 Synchronous Buck Power Stage Modules

    • Infineon SLB9635TT1.2 TPM Embedded Security Controller

    • NXP 74LVC14AD Hex Inverting Schmitt Trigger

    • Nuvoton NPCD379HAKFX

    • Winbond 250128BVFG

    • Nothing to see on the back of the board. Whew!

  24. HP Z1 Teardown: step 24, image 1 of 2 HP Z1 Teardown: step 24, image 2 of 2
    • The HP Z1 sets an unprecedented Repairability Score: 10 out of 10! (10 is easiest to repair)

    • Modular construction allows the user to replace most major components in five minutes.

    • Non-modular components inside are held in place by T15 or T6 Torx screws, or by plastic fasteners. No glue or other funny business is used inside, aside from a taped-down thermal sensor.

    • HP offers the user a host of options on how to fix/troubleshoot the device: a helpful diagram on the inside of the machine, a set of PDF manuals on how to service the machine, and even videos for the major repair procedures!

    • The glass and LCD are the hardest to replace, but still not supremely difficult -- just a bit bulky to move around. They're not fused together, and are instead held in place by those wonderful T15 Torx screws. The most difficult repair in this machine should take under an hour to complete.


Diagram reminds me on diagrams found in old TV-s. Kudos to HP!

Looks like they did a pretty nice job on this. I love how easy it is to open. I'd have to go Xeon with this one. I hope someone does a Hackintosh guide for this lol. hMac anyone?

Excellent guide one of the best Ive seen and the simplicity of construction of this machine is awesome. Almost makes me want to go out and get one just to tear it apart .

Seems like it would make a brilliant "example computer" for a Computer Technology lab. It's the device and the textbook in one, easy package.

Also, there is no better place to store a USB flash drive than in a computer, where it can never be lost.
