HP ZBook Power G915.6" 4K OLED i9-12900H 32GB 1TB RTX A2000 8GB W11P

HP ZBook Power G9 — 15.6" 4K OLED Mobile Workstation

A certified refurbished HP ZBook Power 15.6" G9 with a 14-core Intel Core i9-12900H, NVIDIA RTX A2000 8GB professional graphics, 32GB of DDR5 memory and a 1TB NVMe SSD — on a 4K OLED display covering 100% of DCI-P3. Backed by a 12-month Reboot IT warranty.

Key Benefits

• A colour-accurate 4K OLED panel. This is the specification that sets this machine apart. 3840 × 2160 OLED, 400 nits, HDR 500, and full DCI-P3 coverage — true blacks, per-pixel contrast, and colour you can actually grade against rather than approximate.
• Fourteen cores, twelfth generation. The i9-12900H combines six performance cores with eight efficiency cores — twenty threads in total, boosting to 5.0GHz. Heavy parallel work runs on the P-cores while background tasks stay out of their way.
• 8GB of professional VRAM. The RTX A2000 8GB is ISV-certified for AutoCAD, SolidWorks, Revit and Adobe Creative Cloud, and the doubled memory is what allows larger scenes, textures and datasets to stay resident on the GPU.
• DDR5 memory. 32GB of DDR5-4800 delivers substantially more bandwidth than the DDR4 of the previous generation — which is precisely what a fourteen-core processor needs to stay fed.
• 1TB of NVMe TLC storage. Fast, durable local storage for project files, asset libraries and renders.
• Genuinely portable for a workstation. At roughly 1.93kg it is lighter than most machines carrying this class of graphics, with full-size HDMI 2.0 and gigabit Ethernet still on board.

Performance In Use

The defining feature of this configuration is the display. Most mobile workstations, including the previous generation of this same model, ship with an IPS panel covering the sRGB gamut — perfectly good for CAD linework, and not good enough for colour-critical work. This unit has the 4K OLED: per-pixel illumination, so black is genuinely black rather than backlight leaking through, HDR 500 certification, and 100% of the DCI-P3 cinema gamut. For anyone grading video, retouching, or presenting work to a client, that is the difference between trusting the screen and second-guessing it.

Behind it, the i9-12900H is the first generation of Intel's hybrid architecture in this chassis. Six performance cores handle rendering, simulation and compilation, while eight efficiency cores absorb the background load — sync clients, browser tabs, chat, indexing — that would otherwise steal time from the work. Combined with DDR5-4800 memory bandwidth, sustained multi-core workloads hold up considerably better than raw clock speed alone would suggest.

The RTX A2000 8GB is the part that makes it a workstation rather than a fast laptop. Certification means NVIDIA and the software vendors have validated the drivers against the applications, so viewport behaviour in SolidWorks or Revit is predictable. The 8GB of VRAM — double the G8's — is what lets larger assemblies, higher-resolution textures and bigger datasets stay on the card instead of spilling to system memory. This suits colourists, motion designers, architects and product designers who need both accurate output and the compute to produce it.

Condition Grades

Cosmetic grading describes the casing only. Every unit is fully tested regardless of grade, and the display is checked for uniformity and retention. Batteries are consumable items and carry a 30-day warranty.

Frequently Asked Questions

What makes the OLED panel worth having?

Each pixel emits its own light, so black pixels are switched off entirely rather than lit from behind. That produces contrast an IPS panel cannot match, and combined with 100% DCI-P3 coverage and HDR 500 it means colour on screen is close enough to output that you can make decisions from it.

Should I worry about OLED burn-in?

It is worth knowing about rather than worrying about. Retention happens when a very high-contrast static element stays in the same place for very long periods. Normal professional use with a hidden taskbar, a screen timeout and varied content is not a problem. Every unit we sell has its display checked for uniformity and retention before dispatch.

How is this different from the G8?

Three things. The processor moves to 12th Gen hybrid architecture — 14 cores instead of 8. The graphics card carries 8GB of VRAM instead of 4GB. And the display is OLED rather than IPS. Memory also moves from DDR4 to faster DDR5.

Can I add more memory?

Yes. This unit has 32GB of DDR5-4800 and the platform supports up to 64GB, so memory can be doubled later.

Is the RTX A2000 the same as a GeForce card?

No. It is from NVIDIA's professional range, with drivers certified against applications like AutoCAD, SolidWorks and Revit. A GeForce card may run the same software, but without that validation — which matters if your workplace requires certified hardware.

What condition is the battery in?

Grade A units are tested at 70% or better of original capacity, Grade B at 50–70%. Batteries are consumable and carry a 30-day warranty separate from the 12-month cover on the machine.

What is included, and how is it shipped?

The workstation, its power adapter and cable, and a tax invoice. This unit qualifies for free standard AU shipping, dispatched from our Melbourne warehouse.

Warranty & Why Reboot IT

This workstation is covered by a 12-month warranty (return-to-base) supplied directly by Reboot IT. If something fails within that period we repair or replace it. You deal with us in Melbourne, not an overseas call centre.

Reboot IT has specialised in refurbished business technology since 2001. Every machine is functionally tested, securely data-wiped, cleaned and graded by a technician against a consistent standard — which is why the grade on this listing means the same thing as the grade on every other listing we publish.

A workstation configured like this one — 14-core i9, certified 8GB professional graphics, and a factory 4K OLED panel — is expensive new and depreciates hardest in its first two years. Buying it refurbished is how that specification becomes reachable, and extending the life of a machine this capable is the straightforwardly sustainable choice as well.
