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

Lenovo Yoga C640: Abandoning Windows on ARM
Source: On MSFT English Archive.org version
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 Archive.org version
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 Archive.org version
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 Archive.org version
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.

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 2 cores 3.7 GHz max.) with HyperThreading (4 threads). The integrated memory controller supports up to LPDDR4-2933 and using cTDP up/down the performance can be adjusted by the OEM (10 - 25 Watt possible, 15W default). The integrated graphics adapter clocks from 300 - 1000 MHz and only offers 23 instead of 24 CUs.» Further information can be found in our Comparison of Mobile Processsors.


13.30":

There are hardly any tablets in this display size range anymore. For subnotebooks, on the other hand, it is the standard format.

The advantage of subnotebooks is that the entire laptop can be small and therefore easily portable. The smaller display also has the advantage of requiring less power, which further improves battery life and thus mobility. The disadvantage is that reading texts is more strenuous on the eyes. High resolutions are more likely to be found in standard laptops.

Lenovo: Lenovo ("Le" from English legend, novo (Latin) for new) was founded in 1984 as a Chinese computer trading company. As of 2004, the company was the largest laptop manufacturer in China and, after acquiring IBM's PC division in 2005, the fourth largest in the world. In addition to desktops and notebooks, the company manufactures monitors, projectors, servers, etc, and specializes in developing, manufacturing and marketing consumer electronics, personal computers, software, enterprise solutions and related services.

In 2016, the company ranked first in the world in computer sales. It still held it in 2023 with about 23% global market share. Important product lines are Thinkpad, Legion and Ideapad.

In 2011, it acquired a majority stake in Medion AG, a European computer hardware manufacturer. In 2014, Motorola Mobility was purchased, which gave Lenovo a boost in the smartphone market.


75%: This rating is poor. More than three quarters of the models are rated better. That is rather not a purchase recommendation. Even if verbal ratings in this area do not sound that bad ("sufficient" or "satisfactory"), they are usually euphemisms that disguise a classification as a below-average laptop.
