Lenovo ThinkBook Plus Gen 3 • (i7 12th Gen, 16GB RAM, 512GB SSD, 17.3” Touch Display)

The Lenovo ThinkBook Plus Gen 3 is a premium, productivity-focused laptop built around an idea that most laptops only partially solve: people often need more than one screen, but external monitors are inconvenient to carry. Lenovo’s answer is a full-size 17.3-inch business laptop with a second 8-inch touchscreen integrated directly beside the keyboard. Rather than using a small secondary display on the lid or a detachable accessory, the ThinkBook Plus Gen 3 places a vertical, phone-like display in the palm-rest area, creating a compact two-screen workspace that travels with the user.

Its main 17.3-inch display is unusually wide, using a 21:10 aspect ratio and 3K resolution. This gives it substantially more working space than a typical 16:9 laptop screen, especially for wide spreadsheets, multiple browser windows, presentation editing, coding, timelines, dashboards, and documents viewed side by side. The 120 Hz refresh rate makes scrolling and cursor movement feel smoother, while the 99% DCI-P3 colour coverage, Dolby Vision support, and 400-nit brightness help make the panel suitable for visual work as well as office tasks. It is not merely a large screen: it is designed to act like a flexible desktop workspace in a portable form.

The 8-inch secondary display is the centerpiece of the design. It can be used as an extended Windows display, a duplicated display, or a dedicated control and reference space. A user can keep Microsoft Teams or Zoom chat messages on the small display during a meeting, leave the main screen free for a presentation, write quick notes while reading a document, monitor a calendar or email inbox, control music, or keep a phone-connected app visible. It can also hold reference images, calculations, translation tools, media controls, task lists, or chat conversations without covering the main work area. This arrangement is particularly useful for people who routinely switch between applications and need information available at a glance.

Lenovo also developed productivity features specifically for this dual-screen layout. One example is “waterfall” mode, which extends a long page or document from the main display down into the smaller screen. This can be useful when reading lengthy reports, reviewing web pages, working with vertically structured spreadsheets, or comparing content without repeatedly scrolling. The screen supports touch and pen input, allowing users to annotate, sketch, take handwritten notes, sign documents, or make quick edits. The optional Lenovo E-Color Pen is aimed at creative users: it can sample a colour from a physical object and use companion software to identify closely matching digital and Pantone colour values.

Performance is based on 12th-generation Intel Core H-series processors, with configurations that include Core i5 and Core i7 options. Combined with up to 32 GB of LPDDR5 memory and PCIe NVMe SSD storage, the ThinkBook Plus Gen 3 is designed to handle business multitasking, large spreadsheets, browser-heavy research, collaboration tools, presentations, software development, light photo and video editing, and data analysis. Its Intel Iris Xe integrated graphics are capable for everyday visual and productivity workloads, but the laptop is not intended as a dedicated gaming computer or a workstation for intensive 3D rendering, advanced CAD, or GPU-heavy video effects.

The device also includes features expected from a modern business laptop. It has a Full HD infrared camera for Windows Hello facial recognition, a physical ThinkShutter camera cover for privacy, a fingerprint reader integrated into the power button, and TPM 2.0 hardware security. Audio is handled by Harman/Kardon speakers with Dolby Atmos support, while dual-array microphones help with calls and meetings. Connectivity is strong, with Thunderbolt 4, USB-C, HDMI 2.1, two USB-A ports, Wi‑Fi 6E, and Bluetooth. This makes it practical to connect docks, fast storage, projectors, wired displays, and other office equipment when a larger setup is needed.

Although it has a large 17.3-inch main display and an additional 8-inch screen, the ThinkBook Plus Gen 3 remains relatively slim at roughly 18 mm thick and weighs about 2 kg. It is therefore less portable than a 13- or 14-inch ultrabook, but much easier to travel with than a conventional laptop plus a portable monitor. Its storm-grey aluminum construction, backlit spill-resistant keyboard, glass touchpad, 69 Wh battery, and 100 W USB-C rapid charger reinforce its premium business positioning.

Overall, the ThinkBook Plus Gen 3 is best described as a portable dual-monitor workstation. It is designed for professionals, multitaskers, analysts, creators, executives, remote workers, and students who benefit from keeping several sources of information open at once. Its unusual secondary touchscreen is not a gimmick when used well—it provides a genuinely useful space for communication, notes, controls, reference material, and pen interaction, while the main ultra-wide 3K display remains focused on the primary task.
