Lenovo ThinkBook 14 2-in-1 Gen 4 in-depth review

The Lenovo ThinkBook 14 2-in-1 Gen 4 is a compact business transformer that offers surprisingly good upgradability and port selection. A Meteor Lake-U CPU is hidden under the bonnet. The 15W chip doesn't require significant cooling and it's not thirsty. That's why the battery life is good.It's nice to see that most of the features are standard. This applies to the backlight, the fingerprint reader, the dTPM 2.o chip, and the self-healing BIOS. If you want a Web camera with facial recognition, you have to pay more for this extra.There is just one display variant. It's a 1200p IPS touchscreen with a 60Hz refresh rate and Dolby Vision support. The audio department is represented by two 2W Dolby Atmos speakers.You can check the prices and configurations in our Specs System: https:/[...]

Health-Guard

Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.
