Sascha Mölck | February 2023
"The Lenovo IdeaPad 3 is an enduring office notebook with a powerful Ryzen APU. Lenovo's office all-rounder easily handles office and internet applications as well as modest games - the Ryzen 5 5625U APU and 16 GB of RAM make this possible. The CPU and GPU can work at consistently high clock rates. The emission values are okay, but the noise emissions should be lower under medium to full load. The relatively light notebook (approx. 1.6 kg) achieves practical battery runtimes of about 10 to 11 hours."

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."
