Lenovo ThinkPad X220 laptop i7-2640M 8GB 160GB SSD 12.5" Touch

Business Ultraportable for Mobile Professionals

The Lenovo ThinkPad X220 is a 12.5-inch touchscreen laptop built for business users who need a durable, portable workstation. It runs Windows 8.1 Professional 64-bit on an Intel Core i7-2640M processor with 8GB of DDR3 memory. A 160GB solid-state drive provides the system storage. The HD display resolves at 1366x768 and supports touch input with an included pen.

Thermals and Power in Daily Use

The dual-core i7-2640M operates at a base frequency with turbo up to 3.50 GHz, drawing a typical mobile thermal design power. In normal office workloads the cooling system keeps the chassis comfortable for lap use. Fan noise remains low during document editing, email and video calls. The 160GB SSD produces no mechanical noise and consumes minimal power compared to a hard drive.

Sustained Load Behaviour

Under continuous heavy processing the processor will maintain elevated frequencies within its thermal envelope until the cooling system reaches equilibrium. The Active Protection System parks the drive heads if sudden motion is detected, though the SSD has no moving parts. Shared system memory handles graphics duties, so extended 3D tasks are limited by the integrated video subsystem. The common docking connector allows a quick transition to desktop peripherals for longer sessions.
