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 2TB—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. Modern Standby wakes the system in just one second upon opening the top cover and connects online one second later. Plus, with narrow display bezels and an 88% screen-to-body ratio, you’ll appreciate the larger screen real estate and enjoy the view.
Seize the advantage with vPro
On select models, the ThinkBook 15 Gen 4’s 12th Gen Intel® Core™ i Series processor is enhanced with Intel® vPro® Essentials. This technology, engineered for small business, maximizes productivity, enables smooth multitasking, assures premium connectivity and conferencing, keeps your data secure, and streamlines PC management.
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 colour 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. Do you have trouble finding earbuds when you need them? The optional Versa Bay is an innovative drawer within the laptop chassis that includes and charges a pair of earbuds*.*Earbuds are not available in EMEA.
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, along with 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.
