Lenovo ThinkBook 14 G4 i5 1235U 4.4GHz 8GB 256GB 13.3" W11P | 1yr Wty

The Certified Refurbished Lenovo ThinkBook 14 G4 IAP is a 14-inch business laptop powered by a 12th Gen Intel Core i5-1235U processor, 8GB DDR4 RAM, a 256GB PCIe Gen4 NVMe SSD, and a Full HD 1920×1080 display—running Windows 11 Pro. The i5-1235U is a 12th Gen Alder Lake chip using Intel's hybrid core architecture: two high-performance cores for demanding tasks and eight efficiency cores for background work, which means the processor manages multitasking and sustained workloads more intelligently than the single-architecture 10th and 11th-gen equivalents. The PCIe Gen4 SSD is the fastest storage in this product range—sequential reads around 4,000–5,000 MB/s, roughly double the Gen3 speeds found in the ThinkBook 13s G2—therefore large file operations and application launches are noticeably quicker. The 1080p FHD webcam is a step above the 720p cameras on most refurbished business laptops at this price point, producing sharper video in Teams and calls without any additional hardware. Tested by our technicians in early 2026, this 2022-era ThinkBook is one of the most current-generation configurations available in the refurbished market. Ideal For

The ThinkBook 14 G4 suits professionals who want a larger working display and near-current hardware without paying new prices—think project managers juggling spreadsheets and dashboards across a full 14-inch screen, remote workers who present frequently via video call and benefit from the 1080p webcam, and students in postgraduate or research roles running data tools, reference materials, and writing applications side by side. The built-in RJ45 Ethernet port is a practical addition for users in offices or homes where wired connections are more reliable than Wi-Fi, and where most 13-inch ultrabooks require a dongle.

The 14-inch form factor is larger and marginally heavier than the 13-inch ThinkBook 13s G2 and ThinkPad L13—worth considering for users who prioritise portability above screen size. The soldered 8GB RAM cannot be upgraded, which is the primary constraint to plan around if your workload is memory-intensive. Key Features & Benefits

- Intel Core i5-1235U (12th Gen Alder Lake, up to 4.4GHz Turbo): Hybrid architecture with 2 P-cores and 8 E-cores means the CPU allocates resources between demanding foreground tasks and background processes more efficiently than previous single-architecture designs—translating to better sustained performance during multitasking without the fan noise associated with older chips under load.
- 256GB PCIe Gen4 NVMe SSD: Sequential read speeds around 4,000–5,000 MB/s—approximately double PCIe Gen3 speeds and ten times faster than a SATA SSD. In practice, application launches, Windows updates, and large file transfers complete faster than on any other model in this range.
- 1080p FHD Webcam with Dual-Array Microphones and Privacy Shutter: The FHD webcam produces a meaningfully cleaner video image than the 720p cameras standard on most refurbished business laptops—colleagues and clients see a sharper picture without any additional hardware. The dual-array microphones improve voice capture in open-plan or noisy environments, and the physical privacy shutter provides hardware-level lens coverage.
- 14" Full HD Display (1920×1080, anti-glare): The additional screen real estate over 13-inch alternatives means side-by-side application windows are more usable and spreadsheets display more columns without horizontal scrolling.
- Thunderbolt 4 USB 3.2 Gen2 Type-C: Thunderbolt 4 delivers 40Gb/s data transfer, dual 4K external display support, and up to 100W power delivery for single-cable docking. The additional USB 3.2 Gen2 Type-C port provides a second high-speed connection point independent of the Thunderbolt 4.
- Built-in RJ45 Ethernet: Wired network connectivity without a dongle—increasingly rare on slim 14-inch laptops, and practically useful for office environments, server rooms, or home setups where wired is more reliable than Wi-Fi.
- Wi-Fi 6E (802.11ax 2×2) Bluetooth 5.1: Wi-Fi 6E adds support for the 6GHz band—less congested than 2.4GHz and 5GHz in dense office environments—therefore lower latency and more consistent speeds during video calls in shared workspaces.
- 4-in-1 Card Reader: Supports SD, SDHC, SDXC, and MMC formats—useful for photographers, researchers, or anyone transferring files from cameras or field recording devices without adapters.
- 8GB DDR4-3200 (soldered onboard, non-upgradeable): Cannot be expanded after purchase. Sufficient for standard business multitasking; plan around this ceiling if your workflow regularly involves memory-intensive applications running simultaneously.
