Panasonic's consumer mobile PC, the Let's note QR (CF-QR4), is a 2-in-1 model whose 12.4-inch display rotates so it can also be used as a tablet[1]. Into a compact body smaller than a sheet of A4 paper, it packs long battery life, a rugged design, an AI sensor that detects people, and audio and camera features tuned for video meetings, aiming to cover everything from sales calls and desk work to working on the go[1]. Below is a look at its features based on official information.
A 12.4-inch Body Smaller Than A4, Built Tough
Although it has a 12.4-inch screen, the QR series is smaller than a sheet of A4 paper, and its slim body is thinner than the 20.0 mm diameter of a one-yen coin[1]. The display is an FHD+ panel (1920×1280 dots) with a 3:2 aspect ratio that gives more vertical space, which Panasonic highlights as making long documents and web pages comfortable to view[1]. The bezel has been narrowed to about 5.6 mm, increasing the sense of immersion in the screen[1].
The body uses lightweight, sturdy magnesium alloy and is rated to pass a 76 cm drop test[1]. Anticipating repeated transformation into tablet mode, Panasonic says it also ran its own hinge durability test that repeatedly opens and closes the device to nearly 360 degrees[1]. The wheel pad, which lets you scroll the screen with a fingertip without a mouse, has grown about 2.2 times larger in area than on previous models, making dragging and pinching easier[1].
Long Battery Life and 2-in-1 Usability
Battery life is rated at about 7.6 hours during video playback and about 19.8 hours when idle[1]. By newly developing a low-power-consumption display, Panasonic says idle battery life has been extended by about 30 percent compared with the summer 2023 model (CF-SR/QR)[1]. Both figures are measured under the JEITA Battery Operating Time Measurement Method (Ver. 3.0)[1].
By rotating the touch-panel display, it can be used in tablet style, letting you show materials created in notebook-PC mode directly to the other party[1]. Because it reduces the need to print documents, it is designed for use cases such as sales reps who are frequently out of the office and want to save time returning to the office[1].
An AI Sensor That Detects People
The QR series has an AI sensor that monitors the person in front of the PC[1]. When it detects that you have stepped away, it automatically locks the PC, and when it detects that you are seated again, it wakes it from sleep[1]. If you also set up Windows Hello face authentication, you can resume work seamlessly without any operation[1]. The lock can be shortened to as little as one second through optional settings[1].
For security, when it detects two or more faces in front of the PC, it judges this as shoulder surfing and can display a pop-up icon or blur the entire screen[1]. When the user looks away for a set period, it detects the angle of the face and automatically dims the screen to reduce power consumption[1]. These functions can all be operated from the preinstalled "Panasonic PC AI Device Controller"[1]. Note that the AI sensor may fail to detect correctly depending on factors such as ambient brightness and the position, orientation, or condition of the face, including masks and glasses[1].
Audio and Camera Features for Video Meetings
For video meetings, it is equipped with "COMFORTALK," which makes human voices easier to hear[1]. It consists of three elements: a high-pressure box-type speaker, the sound-effect software "Waves MaxxAudio," and AI noise reduction compatible with Intel GNA[1]. Compared with previous models that built the speaker directly inside the chassis (the CF-SV and CF-QV series), the box-type speaker has higher sound pressure, and Panasonic says it can be used even in a meeting room with multiple people without an external speaker[1]. Waves MaxxAudio offers three presets — hands-free meeting, movie/music, and standard — with the default set to the hands-free meeting mode suited to video conferences[1].
On the camera side, it has an effect function that automatically corrects the brightness of the face according to ambient light and blurs the background other than yourself[1]. It automatically corrects your position so your face appears centered, and optimizes the image with zoom when your face is far away or when multiple people are present[1]. The AI noise reduction learns and reduces sounds that easily intrude during remote work, such as typing noise, the voices of pets and children, and sirens heard from outside[1].
13th Gen Core and a Proprietary Cooling Design
The CF-QR4 is equipped with a 13th-generation Intel Core processor (Core i7)[1]. To draw out CPU performance, it adopts the proprietary "Maxperformer" design, combining a cooling layout that maintains high performance with power-control tuning of the CPU, which Panasonic says keeps performance up even during demanding tasks[1]. It applies heat-dissipation engineering matched to the compact chassis, such as widening the gap above the cooling fins to improve airflow[1].
For power control, it uses Intel's DTT (Dynamic Tuning Technology), finely adjusting power for each CPU operation while monitoring temperatures in various parts of the device[1]. For storage, it adopts a PCIe (Gen4) SSD that transfers data far faster than a Serial ATA connection, shortening the time needed to boot the OS and transfer large volumes of data[1].
Summary
The Let's note QR (CF-QR4) is a 2-in-1 mobile PC that packs a 3:2 display, long battery life, and a rugged design rated for a 76 cm drop test into a 12.4-inch body smaller than A4[1]. It further combines an AI sensor that handles shoulder-surfing protection and automatic locking, audio and camera features for video meetings, and a 13th-gen Core with a proprietary cooling design, resulting in a machine focused on being used while on the move[1].
