Reviews for the Lenovo Yoga C640-13IML-81UE0003GE

80% Lenovo Yoga C640 review: A portable laptop with long-lasting battery
Source: The Indian Express English
The Lenovo Yoga C640 is a great device for middle and upper management users who are on the move always. For these users the 1.35kg weight of this laptop will be a huge advantage, along with the tablet mode that makes it easy to consume content on the move. And there is literally nothing you can’t do with this device, though the 13.3-inch form factor does not make this a device that can be suggested as a desktop replacement. The convertible aspect makes this good for those who need to teach or present stuff all the time.

66% Lenovo Yoga C640 Review
Source: Think Digit English
Despite its middling keyboard, lazy touchpad, sub-par audio, and heavy price tag, the Lenovo Yoga C640 emerges as a satisfactory choice for buyers who want a thin and light convertible laptop with good performance, bundled stylus, and a really long battery life.

Lenovo Yoga C640 (13) review – a gap-filler that is actually very decent
Source: Laptop Media English
So, in the first place, we would want to mention that this laptop feels like a gap-feeling notebook. Somewhere between the Yoga 500 and Yoga 700 series. However, when we got some time with it, and of course, didn’t take into consideration the aforementioned, the Yoga C640 (13) actually does a pretty fine job. And has a great keyboard too.

Intel UHD Graphics 620: Integrated GPU (GT2, 24 EUs) found on some Kaby-Lake-Refresh CPU models (15 W ULV series). Technically identical to the previous Kaby-Lake GPU called HD Graphics 620.

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

» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.


i5-10210U: Comet Lake based low power quad-core processor (technically identical to Whiskey Lake and still produced in 14nm++). The CPU cores can clock between 1.6 and 4.2 GHz (all 4 cores 3.9 GHz max.) with HyperThreading (8 threads). The integrated memory controller supports DDR4-2666 and using cTDP up/down the performance can be adjusted by the OEM (10 - 25 Watt possible, 15W default). Compared to the faster i5-10510U, the level 3 cache was reduced from 8 to 6 MB.» Further information can be found in our Comparison of Mobile Processsors.


13.3":

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.

1.4 kg:

This weight is typical for big tablets, small subnotebooks, ultrabooks and convertibles with a 10-11 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, Lenovo acquired the majority of Medion AG, a European computer hardware manufacturer. 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.


73%: This rating is bad. Most notebooks are better rated. This is not a recommendation for purchase.
