Lenovo ThinkPad T420s i5-2540M 4GB 320GB 14" Windows 7 Pro

ThinkPad T420s 14-inch business laptop

This Lenovo ThinkPad T420s is a 14-inch business laptop built around a dual-core Intel Core i5-2540M processor running at 2.60 GHz. It comes with 4 GB of DDR3 memory and a 320 GB hard drive. Windows 7 Professional 64-bit is pre-installed. Integrated Intel HD Graphics 3000 handles the 1366 x 768 display. A DVD±RW drive and Intel Centrino Wireless-N 1000 provide optical media and Wi-Fi connectivity.

Suits mobile office work; not for modern workloads

The system suits users who need a classic ThinkPad keyboard and legacy Windows 7 compatibility for older business applications. Its dual-core processor and 4 GB memory limit multitasking and modern web browsing. Buyers who need more memory than 8 GB maximum, faster storage interfaces, current operating system support, or discrete graphics performance should look at something else. The non-touch 14.0-inch screen and integrated graphics also rule out creative colour-critical work.

Dual-core i5-2540M at 2.60 GHz decides fit

The 2nd Generation Intel Core i5-2540M dual-core processor at 2.60 GHz is the single specification that determines whether this laptop matches your workload. It defines the performance ceiling for every task from document editing to legacy software execution. If your applications require more cores, higher clocks, or newer instruction sets, this processor will not meet the requirement.
