Chassis, connectors, screen of the Lenovo Ideapad C340-14IML-812 (81TK00E4FR)
Its light silver Platinum chassis that can be opened to 360 ° to transform into a Tablet gives this hybrid PC a sober, elegant but also original design.
The multi-touch touchscreen technology equips the screen, which makes it possible to interact with the software or the system by simple applications of the stylus or at least one finger on it, and this by pressure / gestures.
With its precise Full HD definition and its 16: 9 format, the screen is also very suitable for displaying High Definition content and particularly for videos. Because of its touch technology, the screen is bright: its colors are enhanced but in return, it is subject to reflections in a bright environment (eg outside).
The webcam above the screen takes advantage of the Privacy Shutter function to hide it from prying eyes so that privacy is better respected.
The connectivity built into this 2-in-1 Ultrabook is good, consisting of 1 USB 3.1 Type-C, Bluetooth 4.2 and Wi-Fi ac wireless modules to communicate and connect remotely, an HDMI video output useful in order to easily connect this PC to a TV or a monitor for example, with 1 audio port or even 2 USB 3.0 (compatible with USB 2.0) guaranteeing transfers up to 10 times faster than with USB 2.0 if the a USB 3.0 device is connected to it.
The chiclet keyboard can be backlit which is handy for correctly distinguishing its keys when the ambient light is limited.
As a biometric reader is present just like a TPM 2.0 security chip, it is possible to authenticate in a simple and secure way on the system of this PC by fingerprint recognition, and this via Windows Hello technology.
Performance, autonomy of the Lenovo Ideapad C340-14IML-812 (81TK00E4FR)
The Lenovo Ideapad C340-14IML-812 (81TK00E4FR) is a compact High Definition laptop convertible into a Tablet designed for everyday mobile use.
Side autonomy, in fact put on indeed 8 hours of battery operation in light use for this 2-in-1 Ultrabook whose transport is facilitated by the compactness and the controlled weight.
To do this, this hybrid computer relies on energy-efficient components such as its SSD storage. With its 512 GB, the SSD competes with hard drives in terms of capacity while being much faster, more energy efficient, more robust and quieter.
Result thanks to the SSD, we obtain a daily operation much more reactive and fluid than with a simple hard drive. Software starts / stops and launches are much faster.
The SSD supports the heart of this computer convertible into a tablet. Composed of a low consumption Comet Lake Quad Core i5-10210U processor and 8 GB of RAM, it provides good general performance capable of satisfying many users.
However those who wish to carry out heavy work in processor resources on a regular basis will benefit from turning to a PC equipped with a processor not low consumption.
Ditto for those who wish to play or more generally perform heavy graphics work, because no dedicated graphics card is on board. We can nevertheless obviously watch photos and videos on this 2-in-1 Ultrabook silver thanks to the (admittedly modest) benefits of the Intel UHD 620 part integrated into the Quad Core i5.
