Lenovo ThinkPad E15 Gen 4 15.6" FHD i7-1255U 40GB 1TB business laptop

15.6" FHD business laptop with 40GB RAM

The Lenovo ThinkPad E15 Gen 4 is a 15.6-inch Full HD business laptop powered by a 12th Generation Intel Core i7-1255U processor with 10 cores and 12 threads. It combines 40GB of DDR4 3200 memory with a 1TB PCIe NVMe SSD configured as dual 512GB drives. The anti-glare IPS panel reaches 300 nits and includes TÜV Rheinland low blue light certification. Windows 11 Pro is pre-installed.

Suited for multi-tasking professionals and students

This configuration suits users who need high memory capacity for virtualisation, large datasets or heavy multitasking. The 10-core processor and Iris Xe graphics support dual 4K external displays via HDMI 2.0 and Thunderbolt 4. Buyers who need a touchscreen, discrete graphics, or a higher colour gamut than 45% NTSC should consider other models.

40GB DDR4 3200 memory (8GB soldered + 32GB DIMM)

The single specification that decides fit is the 40GB memory configuration: 8GB is soldered to the board and a 32GB DDR4 3200 DIMM occupies the single upgrade slot. This leaves no internal memory expansion headroom. Verify that 40GB meets your workload ceiling before purchase.
