Quite remarkable in its category, the Dell Inspiron 17 7786 (2in1) is a laptop convertible into a 17-inch tablet, a format that is not generally suitable for this type of modular configuration. thas decided differently and brings together a multimedia configuration that holds up with a last-generation quad Core i7, a significant amount of RAM (16 GB) and a mid-range graphics card MX250. The storage is generous (1TB) with a little vivacity offered by the solution Optane but not to the point of arriving at the level of a dedicated SSD. Also consider some amenities like generous autonomy, a fingerprint reader, backlit keyboard and a sturdy aluminum chassis. The only criticism to make at this stage concerns its cumbersome format,

Chassis, Connectivity, Screen Dell Inspiron 17 7786
For an Inspiron, the Dell Inspiron 17 7786 inherits a beautiful design with a chassis surrounded by aluminum . The assembly is neat but the design remains very sober, preferring a silver tone, smooth and matte surfaces and no aesthetic detail except the fine chrome edging around the touchpad. Needless to say, this PC will go everywhere, in a professional environment as fun.
The weight of the Inspiron 17 7786 is consistent and approaches 3 kg but its format chooses a certain fineness (21.9 mm thick), which is welcome to handle it in tablet mode. Note, however, that it will not go unnoticed on the move and that its weight can quickly weigh at arm\’s length
The keyboard is backlit and includes a keypad , a plus for those who regularly enter numbers.
But what really catches the eye is the 17.3-inch (huge) screen that sustains a feeling of immersion with a slight edge-to-edge design and IPS panel at wide viewing angles . Its Full HD resolution (1920 x 1080 px) provides a good display density to modulate the display or view in the best conditions your High Definition content. In addition, the glossy surface reveals very rich colors but complicates the visibility in bright environment.
The particularity of this PC is therefore in its configuration that installs its screen on hinges rotating 360 degrees . This one can thus switch on both sides of the base for a traditional use, in computer mode, or more original, in mode tent, easel or tablet.
Connectivity is shared on both sides of the PC. It summons all expected interfaces except the Thunderbolt 3. There are two USB 3.1 ports, a USB Type-C , an HDMI output and a multi-format SD card reader. The wireless modules are latest generation (Wifi ac, Bluetooth 5.0) and a fingerprint reader logically takes place at the power button.
Performance, autonomy of the Dell Inspiron 17 7786
The heart of this convertible is powered by a low power 9th generation Quad Core i7-8565U processor , the ultrabook will leave no work aside. The latter gains a significantly higher Turbo Boost frequency (4.6 Ghz) compared to the previous generation (Kaby Lake Refresh) allowing Intel to announce a theoretical gain of around 10%. Concretely, the common use is fully supported (web browsing, Office processing, video) and greedy applications drawing on the multicore architecture (video editing, Photoshop pushed, Lightroom …) do not scare him (all proportions kept nevertheless). Especially since the RAM is generous behind with 16 GB of RAM, enough to enjoy a fluid system even if you multiply the tabs or active applications.
Dedicated to graphic processing, the GeForce MX250 is a mid-range card based on the Pascal architecture (2016). This is just an update of the GeForce MX150 with a small gain in frequency. So do not expect a revolution at this price level although this GPU is a valuable support in common use and to launch some games. The occasional player will be able to practice in HD on a good part of the titles of the market on the condition to make concessions on the sharpness of the rendering.
For a PC that wants to be “nomadic”, the autonomy is quite convincing with a generous total that revolves around 7 hours in Web browsing with active WiFi. What to work a whole day without being disturbed.
Storage comes last in our argument. It is entrusted to a hard drive of significant capacity (1 TB) reinforced with a SSD Optane cache of 16 GB . This system is an interesting alternative to hybrid storage (1.1 TB) and speeds up the system start / stop phases as well as the processing of the most frequently used applications. It is almost even at the level of a hybrid solution with a SATA3 SSD a little slow, ie the gain provided by this “cheap” solution. However, we do not take advantage of SSD storage itself, which is a shame for the end of 2019.
