Lenovo ThinkPad T420 14.0" laptop

The Lenovo ThinkPad T420 is a 14.0" business laptop powered by an Intel Core i7-2620M processor running at 2.70GHz. It comes with 4GB of DDR3 memory and a 320GB hard drive. Windows 7 Professional 64-bit is pre-installed. The integrated graphics and non-touch 1366 x 768 LED display suit office applications and basic multitasking.

Build quality and daily connectivity

The black chassis includes a DVD±RW drive for optical media and a webcam for video calls. Gigabit LAN provides wired network access while 802.11a/b/g wireless covers Wi-Fi needs. Bluetooth 2.1 supports legacy peripherals. An Always-On USB 2.0 port allows charging devices while the system is off. The 6-cell lithium-ion battery powers the unit away from mains power.

Practical limits of the platform

The 4GB memory capacity and 320GB hard drive restrict modern multitasking and large local storage requirements. Windows 7 Professional 64-bit no longer receives security updates, limiting safe internet use. Integrated graphics cannot accelerate demanding 3D or video workloads. Bluetooth 2.1 and 802.11a/b/g wireless standards offer slower speeds and shorter range than current protocols.

Questions about this item

What LAN standard does the ThinkPad T420 use and what is its practical speed cap?

It uses 10/100/1000Mbps Gigabit Ethernet, capping wired throughput at 1000 megabits per second.

What physical drive bay does the 320GB hard drive occupy in this 14.0" chassis?

The 320GB Serial ATA drive fits the standard 2.5-inch internal bay.

How is the 4GB DDR3 memory installed and which step do people often miss?

Two SO-DIMM slots sit under the bottom cover; the common mistake is not seating both modules until the retention clips click.
