If you are willing to accept a slightly bigger height and a bigger size, you will get very long battery runtimes with the big 9-cell battery. It seems a BIOS update of the manufacturer has a negative impact here. The reduced performance under continuous load and an even bigger performance loss on battery is not understandable. Thanks to the SSD, the workstation even works silently in low load scenarios, which makes comfortable office use possible. Although the hardware is significantly faster than the first test model, this hardly has a negative impact on emissions. Apart from CPU performance, the system scores points in special tasks like CAD- or GPGPU applications. In general, the performance is suitable for the target group. Therefore, two essential points of criticism are gone, giving a nicely improved product. Reconciled? Partly! We appreciate that the keyboard works flawlessly and that the ClickPad is fully functional over its full extent. So, our current test sample, with faster hardware, only achieves 1.69 points (multi-core) and 0.36 points (single-core) in Cinebench R11.5 while the first test unit (5.09 points in Cinebench R11.5 Multi) performed significantly better. On battery, the processor only clocks at 799 MHz from the start despite maximum performance settings. This setting can also be used for battery mode, but it is just as ineffective here. We used the setting "Maximize Performance" in the BIOS to maximize the performance and minimize CPU throttling. Quite the contrary, the CPU clock remained at 799 MHz after about 12 minutes. An update to the current BIOS version 2.10 did not improve this. Thereafter, the clock rate remains at 799 MHz. From then on, the clock rate changes from 799 MHz to 3500 MHz and back, repeating in one-minute intervals for about 12 minutes. Afterwards, the clock rate increases to 3.5 GHz again and gradually falls to 3.0 GHz. After the stress test has been running for 13 minutes (Prime95 + FurMark), HWinfo displays a clock rate of 799 MHz for about one minute. However, it seems that it is not fully available for a long period of time (BIOS 1.13, ). The benchmark results of Cinebench R10 32-bit of 5204 points and 20,089 points are very good and are evidence of high CPU performance. The thermal design power is 47 Watts and includes graphics unit, chipset and memory controller. It features the familiar key features like Intel Turbo Boost (up to 3700 MHz) and Hyperthreading (up to eight parallel threads). Intel's Core i7-4800MQ belongs to the most powerful mobile processors of the manufacturer's product range. But, the brightness falls visibly and diffuse reflections become slightly more visible. In the horizontal direction, the colors are rather stable and do not fade or invert. Looking at the screen from above, the image appears yellowish and looking at the screen from below, it looks greenish. In the vertical direction, the image either fades or inverts. The user has to repeatedly adjust the opening angle regardless of the tasks, be it office, multimedia, or image editing, whenever the position is changed slightly since the image quality decreases. While precise colors and a color space as big as possible are not necessary for routine tasks, the vertical viewing angle stability has an impact on everyday tasks in all areas. In our opinion, this gimmick is not recommendable, especially for professional image editing. You can see the differences in the images. The result is much worse than the capabilities of the display. We compared the calibration of the integrated color sensor to our i1 Pro 2's (also from X-Rite) and can say that the performance of the color sensor integrated in the palm rest is insufficient. The subjective impression is not very positive. A pre-post comparison is possible afterwards. Only white point and gamma can be configured. The configuration options of the included software are very meager. The color sensor from X-Rite integrated in the test unit should allow calibrating the display.
