LG Electronics Inc. is a subsidiary of the LG Group. LG is the world's second-biggest maker of televisions and third-biggest maker of mobile phones. With its headquarters in South Korea, the company has 75 subsidiaries worldwide that design and manufacture televisions, home appliances, and telecommunications devices. LG is an international laptop manufacturer of medium size with few reviews.

After a few years, LG largely withdrew from the laptop sector. In the smartphone segment, LG is a medium-sized manufacturer (not among the Top 5 in 2015 and 2016).

75.9%: This rating is not convincing. The laptop is evaluated below average, this is not really a recommendation for purchase.
