Lenovo Z51-70 15.6″ Mainstream Laptop

Lenovo Z51-70

The Lenovo Z51-70 is a mainstream 15.6-inch laptop PC. It’s a step up from the budget-oriented Lenovo G50 series, but lacks top performance of gaming laptops. With its specs, the Z51-70 is a good solution for the daily home and office chores, plus media creation and occasional gaming.

The brushed aluminum palmrest on this otherwise plastic 5.1-pound laptop with 1″ thick profile gives it a hint of luxury and improves durability. The screen is quite sharp thanks to Full HD 1920-by-1080-pixel resolution, but it lacks wide viewing angles found on panels with IPS technology. Touchscreen is missing, too. Inside, the Lenovo Z51-70 carries the 5th Generation Intel Core i5-5200U or i7-5500U dual-core processor, 4 or 8 Gigabytes of system memory, and either a 500GB hard drive or a 1-Terabyte hybrid HDD with 8GB of solid state drive-based storage for improved responsiveness. As for graphics processing, there’s a AMD Radeon R9 M375 4GB mid-range video card option, alongside the default Intel HD 5500 integrated graphics. The R9 M375 is a new laptop GPU on the market and there’s no much info about it available, but you can expect similar performance to the Nvidia’s mid-range counterparts, such as the GeForce GTX 960M.

The keyboard has ergonomically shaped isle-style keys and a dedicated numeric pad, but it lacks key backlight. The trackpad’s click area is physically separated from the multi-touch surface.

The rest of the feature set includes a built-in DVD drive, stereo speakers enhanced by by Dolby audio technology, a 720p webcam, 802.11AC Wi-Fi wireless, Ethernet LAN network connector, Bluetooth, HDMI and VGA video output ports, two USB 3.0 and one USB 2.0 ports, a multiformat digital card reader, and a combo audio port.

The battery life lasts up to 4 hours, according to Lenovo.

    Sir , I’m a animation and gaming. Student. So I need to render images. In the z51-70.
    Can I render in that or can you suggest any other laptops

    • Danijel Z – October 4, 2015:

      For these purposes, I would suggest you a laptop with an Intel Core i7 quad-core processor and a dedicated video card.

      The most of the gaming notebooks have these. You can check them out here:


      These start at around $1000. The Z51-70 can be a solid replacement, especially if you order it with an i7 (only dual-core is available on this model) and a dedicated video card. However, in that case the price will be close to $1000.

    Well I’ve not actually bought it yet but I’m considering buying it. I have a few questions though. I tend to run a number of programs together, so even if I have the i7 core will it lag? (I’m asking this because I’ve had a really bad experience with a lenovo laptop before)

    Also are the graphics good enough for playing FIFA and first person shooters compared to a nvidia GE-Force 4gb.

      I’ve stumbled upon the Asus K501LX-EB71- 15.6″ Full HD, 5th Gen Intel Core i7 5500U, 8GB RAM, 256GB SSD, and NVIDIA GeForce GTX 950M (see gameplays of the 850M on YouTube, these two GPUs are very similar). For $800 at Amazon it seems to be an excellent deal.
