Features:

Cool Under Pressure. Just Like You
The Lenovo ThinkBook 15 Gen 4 (15" Intel) laptop stays cool under pressure. With up to 12th Gen Intel Core processors and optional dual-SSD storage- as big as 1TB- it can handle all your computing needs. Plus, the Intelligent Cooling feature adjusts fan speed, thermal capacity, and battery life to keep the system up and running even under intense use.

Style that's fully functional
Looking for a highly mobile, thin, and sleek laptop? The stylish, dual-tone Lenovo ThinkBook 15 Gen 4 is only 18.9mm / 0.74" thin and starts at just 1.7kg /3.75lbs. Modern Standby wakes the system in just one second upon opening the top cover and connects online one second later. With narrow display bezels and an 88% screen-to-body ratio, youll appreciate the larger screen real estate and enjoy the view.

View your work in a new light
With its FHD display, the ThinkBook 15 Gen 4 offers crisp, flicker-free visuals and includes video resolution upscaling to enhance low-res videos. Options include TÜV Rheinland Low Blue Light certification to ease eye fatigue and 100% sRGB color gamut models that deliver more accurate, lifelike images. For direct interaction, touchscreen models are available, too.

Teleconference like a pro
AI features on the ThinkBook 15 Gen 4 help keep teleconferences quiet and focused by limiting ambient noise. Multiple settings let you tune your conference audio to your environment.

So many connections
As laptops get smaller, some provide fewer connectivity options. Not Lenovo ThinkBooks, which have all the ports you need. For fast file transfers, the ThinkBook 15 Gen 4 laptop has a Thunderbolt 4 port, USB ports, HDMI, and more to connect printers and other peripherals. Plus, speedy WiFi 6E options let you quickly connect to crowded public platforms with little lag-time and buffering.
