Data transfer is facilitated through USB 3.0 and USB-C connectors, as well as a microSD card slot.
The computer is equipped with a multi-touch screen on selected models, enabling navigation through simple touch gestures like tapping, sliding, dragging, and pinching to zoom. For traditional input, it features a six-row keyboard with function keys and a touchpad that supports finger touch and traditional mouse functions. Hotkeys are integrated into the keyboard for quick access to Windows functions and settings, such as muting/unmuting sound, adjusting volume, enabling/disabling microphones, refreshing windows, enabling/disabling the touchpad, turning on/off airplane mode, enabling/disabling the camera, locking/unlocking user accounts, managing external displays, and adjusting display brightness. The hotkey mode can be configured in the UEFI/BIOS setup utility.
For multimedia, the Lenovo 14w includes built-in speakers and microphones, and a camera for taking photos, recording videos, and video conferencing. An audio connector allows for connecting headphones or headsets. The computer can be connected to external displays like projectors, monitors, or HDTVs via USB-C or HDMI connectors, supporting various resolutions and display modes (PC screen only, Duplicate, Extend, Second screen only). Wireless display connectivity is also supported for Miracast®-enabled devices.
Power management features include checking battery status, charging the battery, and monitoring battery temperature. Users can customize power button behaviors to turn off, sleep, or hibernate the computer. The Lenovo Vantage application, preinstalled on the computer, offers a one-stop solution for system updates, hardware settings configuration (battery, camera, screen, keyboard, microphones, speakers, touchpad), health and support information (hardware scan, warranty status, user guide access, tips), and Wi-Fi security.
Security is a key aspect, with options to set administrator, user, and hard disk passwords in the UEFI/BIOS setup utility. The computer also supports power-on passwords for enhanced security.
