Case & Connectivity
The matte black casing of our review sample corresponds to the typical Lenovo-style of this price range. Thanks to the selected surface texture, the device is pleasant and safe to hold. It is not a lightweight at 2.2 kilograms. The height of 2.5 centimeters is also within the standards. Unfortunately, the device's haptics are not convincing. We often discover sharp edges and inadequately rounded parts. Furthermore, the sharp edges do not indomitably contribute to carrying comfort. The display cover and keyboard unit dent easily. The maintenance hatch on the underside does not close flush with the casing. The display is not easy to open despite small hinges, but it only shakes marginally. We cannot say how the hinges will behave after prolonged use. Overall, the build has clear room for improvement.
The mentioned maintenance hatch allows accessing hard drive, working memory, fan and Wi-Fi module. The battery can be removed separately without releasing screws.
We check the SD-card reader's performance with our Toshiba Exceria Pro SDXC 64 GB UHS-II reference card. The read rate is 33.62 MB/s and the write rate 31.19 MB/s in ASSD benchmark. We achieved 26.5 MB/s in copying standard JPG image files (approx. 5 MB each). That is an outcome in the lower field of rates that we have observed.
Size Comparison
Input Devices
The installed chiclet keyboard shines with an ideal key size. The drop is a bit too short and soft, and the keyboard unfortunately yields slightly when typing on it. However, the input device should be satisfactory for occasional office work.
Thanks to its lightly roughened surface, the touchpad situated in the lower area has superb gliding qualities. Multi-touch gestures, such as scrolling through websites, are identified and implemented impeccably. The touchpad always responded reliably to inputs with exception of the corners.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 200 Hz | 90 % brightness setting |  |
The display backlight flickers at 200 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting.
The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.
In comparison: 56 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 552 (minimum: 43 - maximum: 10420) Hz was measured.

Performance
Processor
The incorporated AMD A8-7410 has a base clock of 2.2 GHz that can reach up to 2.5 GHz via Boost. The manufacturer states a maximum power dissipation of 12 - 25 watts (TDP). We test the quad-core processor's performance with Cinebench R15.
The review sample achieves 174 points in the multi-core test, which is on par with Toshiba's rival.Acer's ES1-521 still sports AMD's A8-6410 from the former generation, and consequently its score is 20 points lower.
According to Cinebench R15, performance losses will have to be counted with when often using the review sample without its power supply. Only 146 points is reached in battery mode.
Discussion
System Performance
The 15.6-inch laptop's system generally runs quite smoothly. Occasional lags occurred when multitasking. Users who want a responsive system might consider upgrading via an SSD. With 1960 points, the system is on par with its rivals in PCMark 8 Home.

Storage Device
A 5400 RPM, 1 TB hard drive is installed for storing data. The storage by Western Digital has sequential read and write rates of approximately 100 MB/s. The chosen hard drive model and the resulting outcomes are common for this low price range, and consequently our selection of rivals is on par.

Graphics Card
We know AMD's integrated Radeon R5 from Acer's Aspire ES1. The internal graphics card is also used in the newer Carrizo L platform here. Its application field is mainly limited to basic routine tasks. It will hardly be possible to submerge into the world of computer games. 3DMark 11 confirms this insight. It still achieves a solid 120 points more with 860 points than the almost identically built Toshiba's Satellite C55D.
The additional performance loss in battery mode is particularly aggravating: We only achieve 647 points as soon as the review sample is used without its power supply.

Gaming Performance
We already discovered the meager performance in the graphics benchmark, which also indicates limited gaming readiness. We only managed smooth frame rates using minimum setting in the game BioShock Infinite. However, users who want occasional diversion from office routine should either opt for older classics or prefer casual games from the Windows Store.

Power Consumption
At up to 10.6 watts, the review sample already proves thirstier than some other rivals based on Intel components. The similarly built Toshiba Satellite C55D even requires up to 12.1 watts. Our review sample only demands 30 watts at most during load, which is on par with the rivals. The included 45-watt power supply thus easily copes with all requirements.

Battery Runtime
Lenovo installs a 4-cell battery with a capacity of 31.7 Wh for mobile use. We test its endurance in a real-world scenario by simulating Internet browsing at a brightness of 150 cd/m². Our review sample went idle after approximately 3.5 hours. Acer's Aspire ES1 does a much better job with a runtime of almost five hours.
