LG Gram 15Z90N: Lightweight laptop with great durability


LG usually stands out for what it offers in the world of televisions and monitors, although its laptop segment also has very good features to offer , both in the design section and in its internal performance. This time it is time to settle on the LG 15Z90N-VAP72B , an intermediate model that is worth taking into account.

LG Gram 15Z90N-VAP72B is a mid-range laptop that stands out for the high quality of its manufacturing materials, as well as its reduced overall dimensions and weight that makes it very comfortable to carry. Inside, a 10th generation Intel Core i7 processor is complemented by 8 GB of RAM and a battery with autonomy for up to 18 hours of use .

Lightweight and ultra-resistant design

LG 15Z90N-VAP72B takes up very little space

The most impressive thing about this model is seen at a first glance, as the design maintains an overall classic elegance with a contained overall size of 357.6 x 225.3 x 16.8mm. This reduced thickness is also complemented by a total weight of just 1,120 kilograms, so that there will be no discomfort to carry it with you in your bag or backpack outside the home.

Being marketed in gray for its entire structure, it is also worth mentioning the presence of resistant materials thanks to a nano carbon and magnesium chassis, which has also achieved the military durability standard STD-MIL 810G that confirms its resistance to seven tests such as what they are shock, pressure, humidity, corrosion, extreme temperatures and accumulation of dust.

Finally, new technologies such as secure access when logging in or reactivating the laptop via a power button with support for fingerprint recognition are welcomed . Then, when working at night or in dark environments, your keyboard has a backlight system that makes it possible to easily set the brightness on two levels.

Intermediate performance capacity

LG Gram 15Z90N-VAP72B is for sale in a single color (gray)

Without reaching the benefits of other “Premium” models of the firm, LG 15Z90N-VAP72B will undoubtedly be able to exceed the demands beyond the usual through an integrated Intel Core i7-1065G7 processor (Ice Lake) (speed of 1.30 GHz , turbo up to 3.90 GHz, 8 MB Smart Cache, 15W), accompanied by an 8GB RAM (DDR4 at a frequency of 3200 MHz) and an integrated Intel Iris Plus 655 graphics (4K support at 120Hz).

A solid IPS panel quality has been added to its screen in a 15.6-inch space with a native resolution of 1920 x 1080 pixels , which also incorporates 96% sRGB color spectrum coverage and 300 nits brightness levels. .

In storage it is possible to find 256 GB in available SSD format, although the inclusion of several expansion slots that go from an M.2 (2280) to 4 TB, another classic microSD 3.0 type UHS-I and even a space is appreciated. to increase SODIMM RAM from 4GB to 16GB.

Finally, the laptop runs on the Windows 10 Home 64-bit operating system and has a four-cell Lithium-Ion battery with a capacity of 80 Wh (10336 mAh) that gives enough autonomy for up to 18 hours of mixed use and more than 16 hours of continuous video playback.

Connectivity and sound options

In connectivity there is nothing missing thanks to a total of three USB 3.1 inputs (type-A) as well as a more recent USB 3.1 Gen2 (type-C) with fast charging (18W PD and charging on off, in addition to support for Built-in Thunderbolt 3. Not missing the classic 3.5mm headphone / microphone combo jack and an HDMI video output.

The team does not forget either a webcam with HD quality, LED, and double MEMS microphone, while for its sound system there are two integrated stereo speakers (2 x 1.5W) that add compatibility with advanced audio DAC (3D immersive audio , even without headphones) with DTS: X Ultra equalization .

Comparison with LG Gram 17Z95N

LG 15Z90N-VAP72B has the weakest in its little SSD storage space

If you are making comparisons with other previous releases of the brand, it is possible to find many points in common with what was analyzed in the LG Gram 17Z95N model . And it is that both maintain the same essence of light design although its size grows due to a 17-inch WQXGA screen that also brings its final weight to 1350 grams.

In operation, LG Gram 17Z95N is a clearly superior team due to the presence of a more recent processor, Intel Core i7-1165G7 , while it is accompanied by a 16 GB RAM memory and an internal storage space of 512 GB in SSD format . Of course, the rest of the technical details such as battery, connectivity and sound remain unchanged.
