14-inch ThinkPad T420 for office mobility

The Lenovo ThinkPad T420 is a 14.0-inch notebook built around a dual-core Intel Core i7-2640M processor running at 2.80 GHz with a maximum turbo frequency of 3.46 GHz. It ships with 4 GB of DDR3 memory and a 320 GB hard drive, while Windows 7 Professional 64-bit is pre-installed. A DVD±RW drive, integrated Gigabit LAN and Intel Centrino Wireless-N 1000 provide wired and wireless connectivity, and an Always-On USB 2.0 port allows charging of external devices even when the system is asleep.

Suits single-task office users.

This configuration suits professionals who need a lightweight Windows 7 machine for document editing, email and legacy business applications on the move. Buyers who require more than 4 GB of memory for simultaneous programmes, faster storage for large datasets, or a 64-bit operating system still receiving security updates should consider a different platform. The integrated graphics and dual-core CPU are not intended for video editing, CAD or gaming workloads.

4 GB DDR3 limit defines upgrade potential

The installed 4 GB of DDR3 RAM is the key specification that determines whether this ThinkPad T420 can handle your workload, because the platform does not support larger memory modules or newer memory standards. If your daily tasks stay within this capacity the notebook delivers reliable productivity; if they exceed it the system will bottleneck regardless of processor speed or storage changes.
