	Zymoki-Xux	April 06, 2024
	With an Intel i5-1235U processor, 16 GB RAM, and a 512 GB SSD, this laptop offers solid CPU resources and storage. The 15.6" Full HD display with IPS panel provides a high-quality picture. The inclusion of multiple USB ports and Office trial software makes it suitable for work and entertainment. However, for gaming, additional RAM may be beneficial.
