Reviews for the Lenovo ThinkPad S440

84% Review Lenovo ThinkPad S440 Touch Ultrabook | Notebookcheck
Achilles' heel. The ThinkPad S440 is one of the newest ultrabooks from Lenovo: slim, powerful and enduring. With its current components, clever features and a matted multitouch display the Lenovo ultrabook might be able to put itself right at the top of the competition. We found out if it really does.

AMD Radeon HD 8670M: Lower mid-range graphics card based on the GCN architecture.

Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.  


Haswell-based ULV dual-core processor clocked at 1.8 GHz with Turbo Boost support up to 3.0 GHz. Offers an integrated HD Graphics 4400 and a dual-channel DDR3 memory controller.

Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

1.86 kg:

This weight is typical for very big tablets, subnotebooks, ultrabooks and convertibles with a 11-13 inch display-diagonal.

Lenovo: Lenovo ( "Le" as in the English word legend and "novo" (Latin) for new) was founded in 1984 as a Chinese computer trading company. From 2004, the company has been the largest laptop manufacturer in China and got the fourth largest manufacturer worldwide after the acquisition of IBM's PC division in 2005. In addition to desktops and notebooks, the company also produces monitors, projectors, servers, etc.

In 2011, Medion AG, a European computer hardware manufacturer, owned the majority of the company. In 2014, Lenovo took over Motorola Mobility, which gave them a boost in the smartphone market.


From 2014 to 2016 Lenovo's market share in the global notebook market was 20-21%, ranking second behind HP. However, the distance decreased gradually. In the smartphone market, Lenovo did not belong to the Top 5 global manufacturers in 2016.

84%: This rating should be considered to be average. This is because the proportion of notebooks which have a higher rating is approximately equal to the proportion which have a lower rating.
