Lenovo ThinkBook 15 Gen 4 Business Laptop - Solid Performance

In this review the Lenovo ThinkBook 15 Gen 4 shows up as a practical choice for professionals, small businesses and students who need a dependable, well-rounded laptop without premium price tags. The single biggest reason to buy is the combination of a 10-core Intel Core i7-1255U with a large 40GB of RAM and a 1TB PCIe NVMe SSD, which together deliver consistently smooth multitasking and fast load times for office work, remote meetings and light content creation.

Key Features

• Processor and memory: The Intel Core i7-1255U with 10 cores and 40GB of RAM keeps multiple apps, browser tabs and virtual meetings responsive under typical work loads.
• Fast storage: The 1TB PCIe NVMe M.2 SSD provides snappy boot times and ample on-device storage for documents, large projects and media files.
• Display and webcam: A 15.6in FHD anti-glare display paired with Intel Iris Xe graphics and a 1080p webcam with privacy shutter gives clear visuals and secure video calls.
• Ports and expandability: Thunderbolt 4, USB-C 3.2 Gen 2, HDMI 2.1 and RJ-45 let users connect multiple monitors, wired networks and fast peripherals without adapters.
• Security and convenience: A built-in fingerprint reader and Windows 11 Pro with Copilot deliver quick sign-in and AI-assisted productivity features for business workflows.
• Durability and design: A slim 0.74in profile and MIL-SPEC 810H testing make the chassis both portable and rugged enough for everyday travel.

Who It's For

The ThinkBook 15 Gen 4 is aimed at business users, remote workers and students who need a reliable workhorse that balances performance with connectivity. The powerful i7, large memory and 1TB SSD suit multitasking, spreadsheets, coding sessions and frequent video conferencing.

Those who need a thin-and-light ultraportable with very long battery life or a dedicated graphics workstation for heavy 3D rendering should look elsewhere; this model is tuned for general productivity and connectivity rather than extreme battery endurance or high-end gaming.
