The bezels are a little bit slimmer, and perhaps most importantly, the 14-inch model of the laptop (the 840) now includes an option for discrete graphics - AMD's Radeon RX 540 - which were previously only offered on the 15-inch model (the 850).

There have been rumors that these three EliteBook Laptops will go on sale this month with prices starting from $1,029.

HP offers the ZBook 14u and 15u as highly durable workstation notebooks with MIL-STD certification for bench handling and crash hazard shock.

Weighing at around 1.48 kg, the ZBook 14u G5 is said to be the world's thinnest workstation with the thickness of 17.9mm.

The refreshed HP ZBook series should hit the shelves sometime later this month.

The rest of the specifications including a couple of USB 3.0 ports, Thunderbolt 3 port, HP Premium Collaboration Keyboard which is spill resistant and comes with an optional backlit, Bang & Olufsen stereo speakers, and a 3-cell, 50Wh battery that should keep both the 14u and the 15u alive for up to 10 hours.

To address the high standards of engineers and designers who need a consistent color calibration, the new HP Z27 and HP Z32 are factory color calibrated to meet the requirements of these users' unique workloads.
