80% Lenovo Yoga C640 review: A portable laptop with long-lasting battery
Source: The Indian Express EN→FR Archive.org version
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 EN→FR Archive.org version
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 EN→FR Archive.org version
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.

Lenovo Yoga C640 initial review: All about 4G connectivity
Source: Pocket Lint EN→FR Archive.org version
The Lenovo Yoga C640 is all about 4G LTE connectivity. It's a sensible balance of size and weight, thanks to the 13-inch screen footprint, while the 360-degree hinge provides additional flexibility to use-cases. There might not be the fancy hinge of the top-end C940 model, but with strong specs, purported strong battery life, and a solid design, there's a lot to appeal if you're in the market for an always-connected laptop.

Lenovo Yoga C640: Abandoning Windows on ARM
Source: On MSFT EN→FR 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.

Lenovo Yoga C640 review: The battery life blows us away
Source: Good Gear Guide EN→FR 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 EN→FR 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.

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.

Commentaire

Lenovo: Lenovo ("Le" de la légende anglaise, novo (latin) pour nouveau) a été fondée en 1984 en tant que société chinoise de commerce d'ordinateurs. En 2004, la société était le plus grand fabricant d'ordinateurs portables en Chine et, après l'acquisition de la division PC d'IBM en 2005, le quatrième au monde. En plus des ordinateurs de bureau et des ordinateurs portables, la société fabrique des moniteurs, des projecteurs, des serveurs, etc., et se spécialise dans le développement, la fabrication et la commercialisation d'électronique grand public, d'ordinateurs personnels, de logiciels, de solutions d'entreprise et de services connexes.

En 2016, l'entreprise s'est classée au premier rang mondial des ventes d'ordinateurs. Il le détenait encore en 2023 avec environ 23% de part de marché mondiale. Les gammes de produits importantes sont Thinkpad, Legion et Ideapad.

En 2011, elle a acquis une participation majoritaire dans Medion AG, un fabricant européen de matériel informatique. En 2014, Motorola Mobility a été racheté, ce qui a donné un coup de pouce à Lenovo sur le marché des smartphones.

Ces cartes devraient être capables de faire tourner tout les jeux d'aujourd'hui, mais la plupart d'entre eux uniquement en détails moyens ou faibles et avec des résolution basses. Les plus vieux jeux ou les jeux moins gourmands restent jouables avec de beaux graphismes.
