I'm reluctantly selling my HP Zbook G3 Studio Mobile Workstation,HP IDS DSC E3-1545M Studio G3 BNBPC (Jul 2016)
that's been a pleasure to use for work and play.
It's a powerful workstation suitable for a variety of tasks, such as graphic design, business and casual computing, gaming, and more.

This unit features a 15.6" 4k Display, non-touch, matte, B-LED DreamColor3 UHD UWVA Anti-glare 60 Hz refresh rate, with a maximum resolution of 3840 x 2160, perfect for vivid and detailed imagery.

Equipped with an Intel Xeon CPU E3-1545M Quad Core v5 @2.90GHz and 32GB of RAM, this unit delivers fast and reliable performance. It also includes an NVIDIA Quadro M1000M 4GB GDDR5 Graphics card, along with a 1TB NVMe M.2 SSD for ample speed and storage. 

The stereo sound system is tuned by Bang & Olufsen. 
The charger is 150W, 7.7A, 19.7 V and battery capacity is HP 4Cell 60 WHr Long Life (replaced in 2021).

Windows 10 Pro 64Bit is installed. (NB: MS has not yet made Windows 11 compatible with the Xeon processor)

Connectivity options include 2xThunderbolt 3 ports, 3xUSB 3.0, Gigabit Ethernet, HDMI, SD Card Slot, a headphone aux. port and Kensington Lock point. 

This HP ZBook G3 Studio Mobile Workstation is in excellent working condition* and all photos are of the item for sale.

* NB: Although otherwise fully working perfectly, there is one anomaly - the Workstation closes down, requiring full restart, if the screen is inclined forward (towards the keyboard) from the vertical, not just when the lid is fully closed. I have checked power saver settings but they are not forcing this. As I never use it at that incline, it has never been a problem for me.  If it is a problem for you then you shouldn't bid for this item.
