ASUS Vivobook 14 M1407KA Copilot+ Laptop: features, specs and who it suits

The ASUS Vivobook 14 (model M1407KA-PS74) is a thin everyday laptop built around AMD's Ryzen AI 7 350 processor and Windows Copilot+ features. It pairs a 14-inch 16:10 screen with 16GB of memory and a 512GB solid-state drive. Here is what those specs mean in daily use.

The Ryzen AI 7 350 processor and the NPU

ASUS lists an 8-core, 16-thread processor with integrated AMD Radeon graphics. The "AI" in the name refers to the XDNA neural processing unit (NPU), a dedicated block for AI workloads, rated by ASUS at up to 50 TOPS (trillions of operations per second). An NPU lets tasks such as live captions or background blur run without loading the main cores or draining the battery as quickly.

Eight cores and sixteen threads is plenty for browsing, office work, video calls and light creative editing. The graphics are integrated, so the listing's gaming references are best read as casual and cloud-style gaming, not a dedicated graphics card.

What Copilot+ PC means

Copilot+ is a Microsoft label for Windows PCs with an NPU at or above a set performance level. The listing mentions features such as Recall, Live Captions and generated artwork from text prompts. It notes that some experiences, including Recall, arrive through later Windows updates and vary by region and language, so check Microsoft's current information for what is available on your device.

The display

The 14-inch WUXGA screen has 1920 x 1200 resolution in a 16:10 ratio, which gives a little more vertical space than 16:9 for documents and web pages. ASUS quotes 300 nits of sustained brightness and a 60Hz refresh rate. That is fine for general use; fast-paced gamers often prefer higher refresh rates.

Memory and storage

The laptop has 16GB of memory and a 512GB SSD. ASUS says the drive is PCIe 4.0, a fast interface that helps with boot times and file transfers. Sixteen gigabytes is a comfortable level for multitasking with many browser tabs and several apps. Check whether the memory is upgradeable, because in thin laptops it is often soldered to the board.

Battery, charging and connectivity

ASUS lists a 42Wh battery with up to 12 hours of use, tested with PCMark 10 in Modern Office mode, and notes that real battery life varies with settings and workload. Fast charging is listed as 0 to 100% in 1 hour 20 minutes. Wireless is Wi-Fi 6 and Bluetooth 5.3, and the keyboard is backlit.

Size and weight

The laptop is 0.7 inches thin, and ASUS lists it at 3.22 lb. The 5.2 lb figure in the shipping dimensions likely includes packaging. That makes it easy to carry between home, school and work.

Who it suits

It suits students, home workers and anyone who wants a light Windows laptop for everyday tasks, with a modern processor and an NPU for the new AI features. It also comes with three months of PC Game Pass, as the listing states, subject to Microsoft's terms.

What to check before you buy

• Ports: the listing doesn't give port details, so check USB, HDMI and charging connections against your accessories.
• Upgradability: check whether memory and storage can be changed later.
• Screen: confirm that 300 nits and 60Hz suit how and where you work.
• AI features: verify which Copilot+ features are active in your region and language.
• Subscriptions: read the terms for the included Game Pass period, as it continues automatically unless cancelled.
• Software: confirm that the programs you rely on run on Windows.
