Reviews for the Lenovo Yoga C640-13IML-81UE000TUK

Lenovo Yoga C640: Abandoning Windows on ARM
Source: On MSFT English
At roughly $750 bucks, the Lenovo C640 is a great mid-ranger posing as flagship and would be a steal for anyone looking to replace their currently aging home office. With an FHD or 4K touch display, all-day battery life and modern specs that include Bluetooth 5.0, Wi-Fi 5 connectivity, and USB-C ports as well as and 10th Gen quad-core Intel-powered chip, the Lenovo C640 is a buy if you can get your hands on one.

This Best Buy-exclusive version of the Lenovo Yoga C640-13IML may be saddled with a dual-core i3 processor and cramped storage, but it’s blessed with stellar battery life.

Lenovo Yoga C640 review: The battery life blows us away
Source: Good Gear Guide English
This Best Buy-exclusive version of the Lenovo Yoga C640-13IML may be saddled with a dual-core i3 processor and cramped storage, but it’s blessed with stellar battery life. While it may drag its heels when it comes to multi-core tasks, it cruises right along during everyday computing activities. We’re also happy with its reasonably bright screen and Atmos-enabled speakers. We'd say this is a good choice for budget users who stick to basic productivity tasks. The long battery life makes it a particularly good choice for students spending the day on campus, or a gig worker hopping from a cafe to a lobby sofa to a commuter train (pandemic permitting).

65% Lenovo Yoga C640 review: Hard to recommend, but not for the reason you'd think
Source: Neowin English
Don't get me wrong; the Lenovo Yoga C640 is a solid convertible and offers a lot of value at its $599 starting price point. But again, it just seems to me that there are better options for that price on the market, and some of those options even come from Lenovo. Like I said, the Flex 5 that I'll be reviewing next has a much more powerful AMD Ryzen 5 4500U processor, it actually comes with the pen, and more.

Lenovo Yoga C640 unboxing and first impressions
Source: Neowin English
Announced at IFA 2019, Lenovo's Yoga C640 is the entry level to the company's Yoga lineup. The model that the company sent me costs $599, which isn't bad for a 13.3-inch convertible PC with pen support.

80% Lenovo Yoga C640
Source: PC Mag English
Overall, the Yoga C640 is a well-priced 2-in-1 convertible whose nifty features, like an integrated webcam privacy filter, are nice to have. Perhaps its signature feature is remarkable battery life, which will appeal to buyers who plan to spend a lot of time away from a power outlet.

Comment

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.


i3-10110U: Comet Lake based low power dual-core processor (technically identical to Whiskey Lake and still produced in 14nm++). The CPU cores can clock between 2.1 and 4.1 GHz (all 4 cores 3.7 GHz max.) with HyperThreading (4 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). The integrated graphics card clocks from 300 - 1000 MHz and only offers 23 instead of 24 CUs.» 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.

» To find out how fine a display is, see our DPI List.


1.35 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.


75%: This rating is bad. Most notebooks are better rated. This is not a recommendation for purchase.
