Technical white paper | HP ZBook 15 G2 Mobile Workstation OS/PXE Boot HP ZBook 15 G2 Mobile Workstation users may encounter difficulties loading a Windows 7 image onto a system that is pre-loaded with Windows 8. This problem stems from a system conflict in the preboot execution environment (PXE, often pronounced ‘pixie’): Windows 7 does not support Secure Boot, a UEFI BIOS feature enabled in Windows 8 systems.
Technical white paper | HP ZBook 15 G2 Mobile Workstation Issue A Windows 7 image will not boot on a Windows 8 system when Secure Boot is enabled because Windows 7 does not support Secure Boot and is thus seen as an untrusted OS. If using PXE boot or another operating system loader on a Windows 7 or a Windows 8 downgrade to Windows 7 pre-installed system to load a Windows 7 image, there will not be any issues.

Technical white paper | HP ZBook 15 G2 Mobile Workstation Switch it up When workloads change or the user finds that they really need a different power supply, maybe to shed weight while traveling or add support for a new application, all of the power supply sizes are offered as after market options that customers can purchase at a later time. In the case of a professional using a docking station to connect at work, it is highly recommended to use the higher wattage power supply option.
Technical white paper | HP ZBook 15 G2 Mobile Workstation TN vs IPS displays The two most popular types of displays are the Twisted-Nematic display (TN) and the In-Plane Switching display (IPS). TN displays are the most common display type and also the oldest. While it is an older technology, it still has many advantages like great response rates, high brightness, and low power needs. However, even with these advantages, the bad viewing angles and color shifts make the TN display a compromise.
Technical white paper | HP ZBook 15 G2 Mobile Workstation Refresh rates The refresh rate of a display measures the amount of times the display is updated every second. A higher refresh rate means decreased blurring and ghosting effects when using the display. Ghosting is the effect when an image or video moves on your display and leaves a faint trail. This effect is most often seen in videos on older displays and can be horribly distracting.
Technical white paper | HP ZBook 15 G2 Mobile Workstation Resolution types Many different resolution displays exist and they all have different titles. The difference in all these displays and names is simply the amount of pixels that the screen can display. Table 1, shown below, outlines the differences in the names and resolutions of displays offered in the market. Table 1.

Technical white paper | HP ZBook 15 G2 Mobile Workstation Recap Displays are not a simple thing to understand and many times there is not a simple solution for all tasks. With different resolutions, response rates, viewing angles, bit precision, and display types the choice of display can be overwhelming. However, knowing what these measurements all mean and why they are important is helpful when choosing a display.
Technical white paper | HP ZBook 15 G2 Mobile Workstation Docking Stations The HP Docking Station has three display output connectors and the HP Advanced Docking Station has five display output connectors. The standard Docking Station has VGA, DVI, and DP connectors. The Advanced Docking Station has VGA and four digital display output connectors (two DVI and two DP). Of those four digital display connectors, only two may be used at a time (two DVI, two DP or one DP and one DVI).
Technical white paper | HP ZBook 15 G2 Mobile Workstation Hybrid Graphics By leveraging display outputs from both the integrated Intel® GPU and the discrete GPU, HP ZBook 15 G2 is able to support a large number of independent displays. The usage of both integrated Intel GPU and the discrete GPU is available when Hybrid Graphics is enabled. Hybrid Graphics is always enabled by default on the HP Zbook 15 G2.
Technical white paper | HP ZBook 15 G2 Mobile Workstation SATA to PCIe Technology transition for SSDs This section highlights the transition from SATA protocol to PCIe protocol as it relates to Solid State Storage Devices. A new interface and form factor (M.2) enables this transition of SSD devices onto the PCIe bus. M.2 provides support for various devices, one of its primary focuses is on SSDs with support for either the legacy SATA interface or the quickly developing PCI Express interface.
Technical white paper | HP ZBook 15 G2 Mobile Workstation Introduction to M.2 interface and form factor M.2 is a specification for internally mounted computer expansion cards and associated connectors. Through different keying the M.2 specification supports multiple functions for add-in cards including such devices as WLAN (Wi-Fi), 3G/ LTE (WWAN), and solid-state drives (SSDs). Exposed buses through M.2 are SATA, PCI Express 3.0, SATA 3.0, and USB 3.0 buses. M.
Technical white paper | HP ZBook 15 G2 Mobile Workstation Performance advantage with HP Z Turbo Drive As previously mentioned, current mSATA SSDs connected via a SATA connection are performance limited by the 6 Gb/s ceiling of the SATA bus. With the implementation of the M.2 specification and use of PCIe SSD devices, performance levels now exceed 6 Gb/s. The HP ZBook 15 G2 takes advantage of this opportunity with introduction of HP Z Turbo Drive.
