15.6-inch FHD IPS business laptop
The Lenovo ThinkPad E15 Gen 4 is a 15.6-inch business laptop with a 1920x1080 IPS anti-glare display rated at 300 nits. It runs Windows 11 Pro on an Intel i7-1255U quad-core processor with a 12MB cache and integrated Intel Iris Xe graphics. The system includes 40GB of DDR4 3200MHz memory and a 1TB PCIe NVMe solid-state drive. A 720p HD webcam with ThinkShutter privacy cover, a spill-resistant keyboard with numeric keypad and TrackPoint complete the core package.
Thunderbolt 4 and Wi-Fi 6 connectivity limits
A single Thunderbolt 4 port provides 40Gbps data transfer, Power Delivery 3.0 charging and DisplayPort 1.4 video output through USB4. One USB 3.2 Gen 1 port with Always On charging, one USB 2.0 port, HDMI 1.4b and an RJ-45 Ethernet jack handle legacy peripherals and wired networks. Wireless uses Intel Wi-Fi 6 AX201 2x2 with Bluetooth 5.1. The 65W USB-C adapter powers the 45Wh integrated battery; no Thunderbolt dock or second high-speed video output is available from the laptop itself.
40GB RAM and 1TB NVMe headroom
The 40GB DDR4 configuration supports heavy multitasking, large spreadsheet models and multiple virtual machines without paging. The 1TB NVMe drive holds operating system, applications and a substantial local project library with fast boot and load times. Integrated Iris Xe graphics shares system memory and suits office productivity, video playback and light creative work; it is not sized for sustained 3D rendering, modern gaming workloads or compute tasks requiring dedicated VRAM. Memory is not user-expandable beyond the factory 40GB.
