The Lenovo ThinkPad X220 is a business laptop from the ThinkPad series that was manufactured by Lenovo.[1][2][3][4][5][6][7]
The X220 was designed for mobile professionals, prioritizing portability without sacrificing the performance typically found in larger 14-inch laptops. It was the first in the X-series to move to a 12.5-inch 16:9 widescreen display, which could come in either TN or IPS configurations. [8][9]
This model is known as the last ThinkPad X series to feature the traditional 7-row 'Classic' keyboard layout. Subsequent models, starting with the X230, transitioned to a 6-row island-style 'Chiclet' keyboard design.
A tablet version was also released.[10]
The keyboard from the X220 has been retrofitted in a X230.[11]
Installation of custom BIOS firmware which removes the factory whitelist for Wi-Fi and WWAN cards, allowing for the installation of modern wireless cards, such as the Intel 7260AC. The X220 is a popular target for Coreboot, an open-source firmware replacement that allows for a cleaner boot process and increased security through the me_cleaner utility, neutralizing the Intel Management Engine.
The original Windows 7 operating system is often replaced by users in favor of a Linux based operating system.
The X220 is frequently upgraded with solid-state drives (SSD) to improve performance over the stock hard disk drives. A notable feature of the model's design is its support for two simultaneous internal storage drives: a full-size 7mm 2.5-inch SATA drive in the main bay and a secondary mSATA SSD in the internal Mini-PCIe slot (shared with the WWAN card). While the main bay supports SATA 3.0 speeds (6 Gb/s), the mSATA slot is limited to SATA 2.0 (3 Gb/s).
