Disadvantages of HP ZBook 15u G2:
Graphics could be better; Weak audio
The HP ZBook 15u G2 is a lightweight work notebook that offers a military-standard durable design and solid overall performance.
Design
The HP ZBook 15u G2 sports a suit in three shades of gray, a professional design that looks understatedly sleek and demure - the strong, silent type. The shiny HP logo in the center of the lid is the darkest, while the area surrounding it is a slightly lighter shade of brushed aluminum. It's bordered by another layer of aluminum whose smooth finish matches the rest of the notebook's magnesium-reinforced body.
Durability and Security
Don't let its pressed-suit looks fool you - the ZBook 15u is a tough workstation. It passed MIL-Spec 810G testing, so it's protected against drops from up to 3 feet, altitudes up to 15,000 feet, as well as dust and shocks. It can also withstand extreme temperatures, performing regularly in minus-60 degree weather as well as in a boiling 160 degrees.
Keyboard and Trackpad
The full keyboard on the HP ZBook is comfortable enough to use all day, and backlighting makes it easy to see even when the lights are out. The keys don't have a lot of travel -- just 1.42 millimeters -- and with 60 grams of actuation they are clicky yet soft. On the TypingTestOnline.Org challenge, I managed an average of 80 words per minute, a bit lower than my 90-wpm average.
Audio
The DTS Sound-equipped speakers on the HP ZBook 15u G2 don't provide the best audio quality. Vocals in the Lumineers "Ho Hey" were clear, but the guitars and other mid instruments were weak, sounding like they were being played from miles away.
Performance
Powered by a 2.6 GHz Intel Core i7-5500U dual-core processor, 16GB of RAM and a 256 GB PCIe SSD, my HP ZBook 15u G2 handled multitasking with ease. It never slowed even with 11 Chrome tabs and multiple PDF files open, while streaming music.
On the Geekbench 3 test, which measures overall performance, the ZBook 15u scored 6,892, slightly better than the Lenovo W550s (6,860, with a 2.6-GHz Intel Core i7-5600U CPU), but lower than the mainstream notebook category average (9,259) and the monstrously powerful MSI WS60 (13,003, with a 2.5 GHz Core i7-4710HQ CPU).
HP ZBook 15u G2 Battery Life
The HP ZBook 15u G2 lasted 6 hours and 44 minutes on the Laptop Mag Battery Test (Web surfing via Wi-Fi). That's about half an hour longer than the mainstream category average of 6:12, and more than twice as long as the 3:05 battery life on the MSI WS60. However, the Lenovo W550s beats them all out with a crazy 15:54 life, thanks to its 3-cell and 6-cell 72 watt-hour batteries.

Graphics
The HP ZBook 15u G2 comes with an AMD FirePro M4170 GPU, which is competent, but not the fastest on the market. On the 3DMark Fire Strike graphics benchmark test, the system scored 1,461, which is on a par with the Lenovo W550s (1,457 with Nvidia Quadro K620M graphics) but isn't nearly as good as the MSI WS60 (1,649 with Nvidia Quadro K2100M graphics).
In World of Warcraft, the ZBook 15u notched 22 frames per second at 1920 x 1080 on full settings. That's the worst of the bunch, with the MSI WS60 (44 fps) and the Lenovo W550s (36 fps) both performing better at the same settings.
Software and Warranty
My review model of the HP ZBook 15u G2 came with Windows 7 Professional 64, but it's also available with Windows 8. It also has programs such as HP Client Security for software- and hardware-level protection of your information, and HP Drive Encryption. HP Performance Advisor lets you fine-tune your device's settings based on your most popular applications.
The ZBook 15u comes with HP's standard 3-year limited warranty, which covers parts, labor and online service.
