Overview

The Lenovo ThinkPad E15 G2 as configured here runs the Intel Core i7-1355U, a 13th-generation Raptor Lake U-series chip with 2 Performance-cores boosting to 5GHz and 8 Efficiency-cores handling background tasks — 10 cores and 12 threads total within a 15W TDP envelope. That TDP ceiling keeps the system cool and quiet in a 3.74lb chassis while Intel's Thread Director scheduler keeps the fast P-cores available for foreground applications. The 24GB DDR4 total RAM (8GB soldered + 16GB SO-DIMM) is a practical sweet spot for professional use: enough headroom to run a Linux VM, a full browser session, and a data analysis environment concurrently. The 1TB NVMe SSD on the PCIe bus provides fast primary storage, and Thunderbolt 4 on the Type-C port ensures the laptop can expand to a full multi-display workstation via a single cable to a TB4 dock.

The ThinkPad E15 G2 targets business professionals and developers who require a portable machine capable of sustained productivity workloads — not just light office use. The 10-core i7, 24GB RAM, and TB4 port collectively address the three most common professional pain points: parallelized tasks (compilation, data processing), memory-intensive applications (large spreadsheets, virtual machines), and single-cable docking. The 720p webcam and fingerprint reader are present for video conferencing and secure login without additional peripherals. The 47WHr battery is the pragmatic compromise — adequate for a full workday of productivity tasks, but users who routinely work unplugged for 8+ hours under load should factor in the power adapter. For desk-anchored professionals who occasionally travel, the Thunderbolt 4 port and USB-C PD charging make the transition between mobile and docked use seamless.

Pros & Cons

👍 Pros

  • i7-1355U's 10-core architecture (2P+8E) with a 5GHz P-core ceiling handles multi-tasking workloads — simultaneous compilation, video calls, and background sync — without the single-core bottleneck of pure dual-core designs.
  • Thunderbolt 4 port supports eGPU enclosures, dual 4K displays from a single cable, and fast external NVMe at 40Gbps — the highest-bandwidth single-port expansion available on any laptop form factor.
  • 24GB DDR4 total RAM eliminates memory pressure in workloads like large browser sessions, virtual machines, or data analysis notebooks that regularly exhaust 16GB configurations.
  • 1TB PCIe NVMe SSD on the M.2 2242 interface provides fast primary storage; the 2242 form factor is less common than 2280 but replaceable with aftermarket modules.
  • 65W USB-C power delivery charging via Thunderbolt 4 enables charging from universal USB-C PD chargers, reducing travel accessory dependency.

👎 Cons

  • The single SO-DIMM slot means one of the two memory modules (the 8GB onboard) cannot be upgraded or removed — maximum addressable RAM is limited to 8GB onboard plus whatever SO-DIMM module is installed.
  • M.2 2242 form factor for the NVMe SSD is less widely available in high-capacity options than the standard 2280 form factor, potentially constraining future storage upgrades to lower-capacity or higher-cost modules.
  • Only one USB 2.0 Type-A port is available alongside the Thunderbolt 4 and USB 3.2 Type-C ports — USB-A peripheral connectivity is limited without the included hub.
  • The 47WHr battery is modest for a machine with a 10-core processor; sustained high-load tasks (compilation, long video renders) will deplete the battery faster than the idle-state estimate suggests.
  • Listed as seller-opened/upgraded with Windows 10 Pro pre-installed; users expecting Windows 11 will need to perform the upgrade themselves, and the i7-1355U's 13th-gen status should make it straightforwardly eligible.

Frequently Asked Questions

There is a discrepancy between the product title (15.6" FHD 1920x1080) and the features section (16.0" IPS 1920x1200). The UXGA 1920x1200 panel provides a taller 16:10 aspect ratio with more vertical real estate than standard 16:9 FHD — meaningfully better for document editing and coding. Confirm the actual panel with the seller before purchasing if the display spec is critical to your decision.
The i7-1355U has 2 Performance-cores (up to 5GHz) and 8 Efficiency-cores, totaling 10 cores and 12 threads. Windows 11's Thread Director scheduler assigns latency-sensitive tasks to P-cores and background tasks to E-cores. In practice this means snappy UI responsiveness while background processes (indexing, antivirus, updates) don't compete for the fast cores — a substantial real-world improvement over pure dual-core designs.
8GB is soldered onboard (non-removable) and 16GB is installed in the single SO-DIMM slot. This creates an asymmetric dual-channel configuration that still provides most of the bandwidth benefit of dual-channel, though a matched 8+8 or 16+16 configuration would be marginally more optimal. The SO-DIMM slot can be upgraded; removing the 16GB module and replacing with a 32GB SO-DIMM would bring total RAM to 40GB.
Yes. Thunderbolt 4 maintains the 40Gbps bandwidth of TB3 and adds mandatory support for two 4K display outputs and PCIe tunneling at minimum 32Gbps — the latter is what eGPU enclosures require. Whether Intel Iris Xe and eGPU configurations coexist optimally depends on the enclosure and GPU driver implementation, but TB4 compliance ensures the protocol-level support is present.
At 47WHr with a 15W-class processor, expect 6–8 hours under mixed productivity workloads. The 65W USB-C power delivery charging means any USB-C PD charger above 65W — including phone chargers in a pinch — will charge the system, which is a meaningful advantage over proprietary barrel-connector chargers.
