Lenovo ThinkBook 15 Gen 4 Business Laptop - Durable, Well Connected

In this review of the Lenovo ThinkBook 15 Gen 4 the bottom line is simple: it is a sensible commercial laptop for professionals who need durable build quality and broad connectivity without a premium price. The ThinkBook targets small business users, educators and remote workers who value a full 15.6' FHD display, long list of ports and a fast configuration - here with an Intel Core i7-1255U, 40GB of RAM and a 1TB PCIe NVMe SSD - that balances everyday productivity and multitasking with practical security features like a fingerprint reader and webcam privacy shutter.

Key Features

• Performance: The Intel Core i7-1255U with 10 cores and 40GB of RAM keeps spreadsheets, multiple browser tabs and light content work responsive for most office workflows.
• Storage: The 1TB PCIe NVMe M.2 SSD provides fast boot and application load times, reducing wait during daily tasks and large file transfers.
• Display and webcam: The 15.6' FHD anti-glare panel offers clear visuals with reduced reflections while the 1080p webcam with privacy shutter is useful for secure video calls.
• Connectivity: Thunderbolt 4, HDMI 2.1, USB-C and USB-A ports plus RJ45 and a 4-in-1 card reader mean you can connect multiple monitors and peripherals without adapters.
• Security and build: A built-in fingerprint reader and MIL-SPEC tested chassis deliver practical security and sturdiness for everyday travel and business use.
• Wireless and OS: Wi-Fi 6, Bluetooth 5.1 and Windows 11 Pro with Copilot add modern wireless speed and AI-assisted productivity.

Who It's For

The ThinkBook 15 Gen 4 is best for small business owners, remote employees and students who need a dependable 15.6' laptop with strong I/O options and a roomy screen for multitasking. It fits users who prefer a business-class machine that is thin and reasonably portable but still includes full-size ports like RJ45 and HDMI.

Those who should look elsewhere include users seeking ultraportable sub 3 lb laptops for all-day carry or gamers wanting discrete high-end GPU performance; while the integrated Intel Iris Xe handles casual gaming and streaming, it is not a purpose-built gaming rig.

Cons

• Some users report occasional trackpad or responsiveness issues and others note it feels heavier than very thin ultrabooks.
• Not targeted at high-end gaming or workstation-level GPU tasks.
