HT Tech

Robin Sinha | February 2021
"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."

Benjamin Herzig | December 2023
"We like a lot about this laptop. It has many ports, with the inclusion of RJ45-Ethernet as a defining feature. WWAN is upgradable for maximum flexibility and the ThinkPad has many security functions. Working with the ThinkPad input devices is a lot of fun, and Lenovo puts in a serviceable Low Power panel. The AMD Ryzen 7 Pro 7840U delivers a great performance and does not drain the battery fast. Fan noise and temperatures are nothing special, but also far away from bad. With the user replaceable keyboard, the ThinkPad T14 Gen 4 has a special feature rarely present on most modern laptops."
