Write Review / Ask a question about Lenovo ThinkPad T420 423665U
Earlier this year, Lenovo unveiled a laptop with a stretchable screen, but that won't be the company's only unusual model this year. Well-known insider Evan Blass (@evleaks) published images of a laptop with a solar-charging feature.
Redmi has unveiled updated versions of its signature Book Pro 14 and Pro 16 laptops. The 2025 models are equipped not only with powerful hardware, but also with screens that combine accurate color reproduction with high refresh rates. In addition, the new products boast a dedicated chip to accelerate local neural networks.
Usually, laptop manufacturers have to choose between a thick top bezel or a cutout in the matrix to accommodate a webcam. Lenovo has approached the problem more creatively: the new laptop Yoga Air X AI Yuanqi Edition is the first model on the market with a camera located under the surface of the screen.
