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.
