Chassis, connectors, screen of Lenovo Yoga C640-13IML LTE (81XL000SFR)
It sports an elegant and discreet but also original design with its dark silver Iron Gray aluminum frame that can be opened to 360 ° to transform it into a Tablet.
The screen takes advantage of multi-touch touch technology: by applying at least one finger on it or the stylus provided, by touch / gesture, you can interact with the system and software.
Due to its tactile aspect, the screen is bright: it therefore enhances the colors but proves to be subject to reflections in a bright environment (eg outside).
The screen also has significant vertical and horizontal viewing angles as well and offers more faithful colorimetry than average thanks to its IPS technology. Thanks to its precise Full HD definition and its 16: 9 format, the screen lends itself well to displaying High Definition content and in particular videos.
As a biometric reader is integrated seconded by a TPM 2.0 security chip, one can authenticate in a simple and secure way on the system via Windows Hello technology.
A backlight system also equips the chiclet keyboard, which is very useful for distinguishing its keys in dim light.
In terms of connectivity, this 2-in-1 Ultrabook has reduced connectivity, without HDMI which may disappoint some. We find integrated 1 USB 3.1 Type-C, wireless modules Bluetooth 5.0 and Wi-Fi ac to communicate and connect remotely, an audio port but also 2 standard USB 3.0 (compatible USB 2.0) ensuring transfers taking place up to 10 times faster than USB 2.0 if you connect USB 3.0 devices to it.
Note also that if necessary, you can always get a USB to HDMI adapter , USB-C to HDMI , USB to Ethernet or USB-C to Ethernet .
Always on the connection side, this ultraportable hybrid also stands out with its 4G module allowing connection to the Internet via mobile telephone networks (subject to a subscription).
Performance, autonomy of Lenovo Yoga C640-13IML LTE (81XL000SFR)
The Lenovo Yoga C640-13IML LTE (81XL000SFR) is aimed at those looking for an ultra-portable High Definition very autonomous and convertible into a Tablet for everyday mobile use.
Easy to transport due to its compactness, finesse and lightness, this Ultrabook can last about 20 hours on battery in light use!
Despite everything it delivers good general performance able to satisfy many users because it is built around a Quad Core i7-10510U processor with low consumption Comet Lake and a good amount of RAM of 16 GB above average very useful in multitasking and which allows you to see well coming to this level.
It must however be borne in mind that to carry out heavy work in processor resources on a regular basis, it will be beneficial to turn to a PC equipped with a non-low-consumption processor (but this implies less autonomy, a slightly more bulky, etc.)
This 2-in-1 Ultraobok is not designed for demanding graphics processing like games since it does not carry a dedicated graphics card. However, it obviously allows you to view photos and videos thanks to the modest benefits of the Intel UHD 620 solution integrated into the Quad Core i7.
In any case, the on-board SSD storage clearly reinforces daily responsiveness compared to a hard drive. Compared to the latter, remember that an SSD is silent, more energy efficient, more robust but also much faster.
Result thanks to the SSD, we benefit for example from start / stop but also software launches much faster than with a simple hard drive.
Here, we are dealing with a 512 GB SSD, a capacity that rivals hard drives. And if you need additional space, you can always rely on an external storage unit like a USB 3.0 device to benefit from fast transfers.
