Lenovo ThinkBook 13x G2 IAP 21AT0010US laptop i7-1255U 16GB 512GB

13.3" WQXGA ultraportable for professionals

The Lenovo ThinkBook 13x G2 IAP is a 13.3-inch Windows 11 Pro laptop built around a 10-core Intel Core i7-1255U processor. Sixteen gigabytes of LPDDR5 4800 memory and a 512GB PCIe SSD are soldered on board. The IPS panel delivers 2560 x 1600 resolution at 400 nits with 100% sRGB coverage and a glossy glass finish. Integrated Intel Iris Xe graphics share system memory. Two Thunderbolt 4 ports handle data, power delivery and DisplayPort 1.4. Wi-Fi 6E and Bluetooth 5.2 provide wireless connectivity. A fingerprint reader secures logins.

Not for memory or storage upgrades

This configuration suits mobile professionals who value a light chassis, sharp colour-accurate display and fast wired docking via Thunderbolt 4. Buyers who need more storage or the ability to add RAM later cannot expand this unit because both memory slots are populated onboard and no additional drive bays exist. Users wanting a touchscreen should look elsewhere as the panel is non-touch. Gamers or creators requiring discrete GPU performance will not find it here.

Soldered 16GB LPDDR5 4800 memory

The single specification that decides fit is the fixed 16GB LPDDR5 4800 configuration. With zero available memory slots, the capacity cannot be increased after purchase. If your workflow regularly exceeds 16GB — heavy virtualisation, large dataset analysis or complex multitasking — this laptop will throttle to swap and cannot be remedied. For workloads that stay within 16GB, the fast LPDDR5 bandwidth supports the 10-core i7-1255U and Iris Xe graphics efficiently.
