The HP ZBook Firefly 15 is a 15.6-inch mobile workstation built for engineers, designers and other professionals who need certified graphics drivers in a chassis light enough to travel. HP sold it across two generations, the G7 (2020, 10th Gen Intel Core) and the G8 (2021, 11th Gen Intel Core), and both still hold real resale value because ISV-certified workstations have a longer working life than consumer laptops. If your unit matches one of the HP part numbers this page tracks, including 1Y5X9UT, 3G0E2UT and similar codes, you have the right family. Pick your processor, graphics option and condition in the configurator above for an instant cash offer, or see how the process works before you commit. You can also browse other laptops we buy if you are not sure this is the right listing yet.

Confirm you have the ZBook Firefly 15 G7 or G8

The fastest way to confirm your exact configuration is through Windows itself. Press Windows key + R, type msinfo32, and press Enter. The System Model field will read "HP ZBook Firefly 15 G7" or "HP ZBook Firefly 15 G8." The same window lists your installed processor and RAM, which you will need for an accurate quote. Alternatively, run dxdiag from the same Run dialog to see the processor and installed graphics card on the System and Display tabs.

ZBook Firefly 15 G7

  • Ships with a 10th Gen Intel Core i5 or i7
  • Pairs most often with NVIDIA Quadro P520 graphics or integrated Intel UHD
  • Released in 2020

ZBook Firefly 15 G8

  • Ships with an 11th Gen Intel Core i5 or i7
  • Pairs most often with NVIDIA T500 graphics or integrated Intel Iris Xe
  • Released in 2021

Prefer a visual check? Flip the laptop over and read the regulatory label near the center of the base panel. It lists the full product name and the HP part number. If that label has worn off, the processor generation printed under Task Manager's Performance tab (10th vs 11th Gen) will tell you which chassis year you are holding.

Core hardware configurations

Processor

  • Intel Core i5, 10th Gen (G7)
  • Intel Core i7, 10th Gen (G7)
  • Intel Core i5, 11th Gen (G8)
  • Intel Core i7, 11th Gen (G8)

Graphics

  • Integrated Intel graphics (UHD on G7, Iris Xe on G8)
  • NVIDIA Quadro P520 discrete GPU (G7)
  • NVIDIA T500 discrete GPU (G8)

A discrete NVIDIA GPU moves the resale value more than any other single option, since it is the main reason CAD and 3D users seek out this line.

Memory

  • A portion of RAM is soldered to the board
  • One SODIMM slot remains user-accessible for an upgrade

Storage

  • Single M.2 PCIe NVMe SSD slot
  • No 2.5-inch drive bay, in keeping with the thin chassis

Display & audio

Display

Most units carry a 15.6-inch FHD (1920x1080) anti-glare panel. Some configurations add HP's integrated Sure View privacy screen, which darkens the viewing angle at the press of a key.

Audio

Speakers are tuned with Bang & Olufsen audio processing, typical of HP's business and workstation lines from this period.

Security

A fingerprint reader is built into the palm rest, and an IR camera supports Windows Hello facial login on most configurations.

Ports & connectivity

Both generations keep a full-size port selection rather than trimming down to USB-C only, which matters if you dock this machine to external monitors or wired peripherals.

Left side
  • Thunderbolt USB-C (Thunderbolt 3 on G7, Thunderbolt 4 on G8)
  • USB-A 3.1
  • HDMI
Right side
  • USB-A 3.1
  • RJ-45 Ethernet
  • Headphone/microphone combo jack
  • Kensington lock slot

Wi-Fi 6 Bluetooth 5 Optional WWAN (LTE) Thunderbolt USB-C Full-size Ethernet Fingerprint reader ISV-certified GPU option

Battery, build & more

Battery

A multi-cell internal battery ships with HP Fast Charge support on most configurations, letting the pack recover a useful charge in a short session on wall power.

Build

The chassis mixes aluminum and magnesium and is tested against MIL-STD-810H standards for drops, dust and vibration. It is notably light for a workstation-class laptop, which was the point of the Firefly line.

Software

Units originally shipped with Windows 10 Pro, with most eligible for a Windows 11 upgrade depending on TPM and processor generation.

Market positioning

ISV-certified mobile workstations depreciate more slowly than consumer ultrabooks because CAD, engineering and video shops keep buying them used to run licensed professional software.

Frequently asked questions

01 How do I find the model number and exact configuration?
Open msinfo32 through the Windows Run dialog (Windows key + R) and read the System Model field, which will show "HP ZBook Firefly 15 G7" or "G8." The same screen lists installed RAM, and dxdiag will show the exact processor and graphics card. You can also check the regulatory label on the bottom panel for the HP part number, which narrows down the original factory configuration. Our HP model number guide walks through the same steps with photos if you want a visual reference.
02 How do I tell it apart from the ZBook Firefly 14?
Screen size is the giveaway: the Firefly 15 has a 15.6-inch display and the Firefly 14 has a 14-inch display, so measuring the panel diagonally settles it instantly. The 15-inch chassis also has a numeric layout difference and a slightly larger footprint. If you are relying on msinfo32 instead, the System Model field will spell out "15" or "14" directly, which removes any guesswork.
03 Can I sell it with a cracked screen, weak battery, or a locked account?
Yes, most cosmetic and functional damage is fine, and the condition picker above adjusts the offer for exactly this. A cracked screen, a battery that no longer holds a full charge, or a unit that will not power on can still qualify. What cannot ship is a laptop still signed into a Microsoft account with device lock enabled. Remove your account, or provide the login credentials, before you send it in. If you are unsure whether the machine is locked, sign into Windows once to check under Settings → Accounts.
04 What raises the trade-in value the most?
A discrete NVIDIA GPU (Quadro P520 or T500) raises the offer more than any other configuration choice, since it is the reason buyers seek this line out for CAD and 3D work. A higher RAM or storage tier helps too, along with clean cosmetic condition, an included original charger, and a battery that still holds a reasonable charge. Selling before a new generation supersedes yours also keeps the offer higher, since ISV-certified workstations still depreciate over time even if more slowly than consumer laptops.
05 How do I erase it and remove my accounts, and how do I get paid?
Go to Settings → System → Recovery → Reset this PC and choose to remove everything and clean the drive. Before you reset, go to your Microsoft account online and remove this device from your account list, and if BitLocker is enabled, suspend it first so the reset completes cleanly. Once the reset finishes, the laptop is ready to ship. Shipping is free and insured, and payment goes out after our team tests the unit, by PayPal, Venmo, Zelle, CashApp or check. Full details on the wipe process are in our data erasure protocols.
