HP ZBook 15 G6 Certified Refurbished Mobile Workstation
Experience professional-grade computing power with the HP ZBook 15 G6 featuring an Intel Core i7-9750H processor (2.60 GHz, up to 4.5 GHz Turbo, 6 cores, 9th Gen), 16 GB DDR4-2667 SODIMM RAM, dual storage with 512 GB NVMe SSD and 1 TB SATA HDD, NVIDIA Quadro T1000 4GB GDDR5 graphics, 15.6-inch FHD display (1920x1080), Wi‑Fi 6 AX200, LTE‑Advanced connectivity, and Windows 11 Pro pre-installed. This certified refurbished workstation from Reboot IT combines exceptional performance with outstanding value, delivering the reliability professionals demand for CAD, 3D modelling, video editing, and intensive multitasking applications.
Professional Performance for Demanding Workloads
The HP ZBook 15 G6 excels at handling resource-intensive professional applications thanks to its 6-core Intel Core i7-9750H processor with 12 MB cache and the NVIDIA Quadro T1000 dedicated graphics card. The dual storage configuration provides rapid system responsiveness through the 512 GB PCIe NVMe M.2 SSD whilst the 1 TB SATA HDD offers ample space for large project files, media libraries, and extensive datasets. This workstation is ideal for engineers, architects, designers, content creators, and business professionals who require certified, refurbished equipment that delivers uncompromising performance without the premium price tag.
Windows 11 Pro Benefits
Windows 11 Pro delivers advanced security features including BitLocker encryption, enhanced device management capabilities, and domain join functionality perfect for business environments. The operating system provides improved productivity tools such as Microsoft Teams integration, Snap Layouts for efficient multitasking, and optimised workflows that enhance collaboration. However, Windows 11 Pro requires hardware compatibility including TPM 2.0 (which this workstation features) and may present a learning curve for users accustomed to previous Windows versions, though the enhanced security and modern interface generally outweigh these minor considerations.

Understanding Cosmetic Grades
Excellent Grade laptops show barely any signs of previous use with only very minor scuffing or light wear on the keyboard from minimal standard use, and screens remain pristine without scratches, cracks, dead pixels, or blemishes. Good Grade laptops are fully functional with more visible cosmetic wear including possible small dings or dents on covers, heavier keyboard wear, and screens may feature uneven light diffusion or subtle blemishes, though screens will not have cracks. Both grades deliver identical performance and are covered by the same comprehensive warranty, with the grade reflecting only cosmetic condition.

Refurbished Computers - Cosmetic Grading Guide
Our supplier's refurbished hardware is typically graded either "Excellent" or "Good", however, some legacy products were graded under a letter grading system (A, B, C). Please find the definitions for each grade below and contact us if you're uncertain of a device's grade.
Used Smartphone / Refurbished Mobile Phones
"Excellent" Grade
Devices in this category appear like new, with very minor wear. Expect light or fine scratches on the screen that are shallow enough not to catch on a fingernail. The edge around the glass is virtually flawless, save for possible light scratching around the power port. The back plate may show light/fine scratches, including on the Apple logo, with any discoloration being minimal.
"Good" Grade
These devices are characterized by being fully tested and functional even if they have body scratches, minor paint chips, or a small hairline crack on the screen. Screens are free from dead pixels but may exhibit slight scratching from moderate use.
Refurbished Desktops, Laptops and Monitors
"Excellent" Grade - Laptops
Reserved for units that show barely any signs of previous use, these laptops may exhibit very minor scuffing or abrasions, associated only with minimal standard use. The keyboards show light wear, and importantly, the screens are pristine, free from any scratches, cracks, chips, dead pixels, dark spots, discoloration, or blemishes.
"Excellent" Grade - Desktops
Desktop PCs in the "Excellent" grade category are free from deep scratches, cracks, paint chips, or any broken/missing pieces, ensuring a sleek and almost-new aesthetic.
"Excellent" Grade - Monitors

"Good" Grade - Desktops
