Storage is handled by a 1 TB NVMe PCIe 4.0 SSD. Connectivity options include two USB 3.2 Gen 2 Type-C ports, two USB 3.2 Gen 1 Type-A ports, an HDMI 1.4 output, Bluetooth 5.2, and Wi-Fi 6 support. The 57 Wh battery includes sleep-and-charge capability, and the system scored 23,805 on PassMark multi-threaded benchmarks.

Pros
  • The OLED/AMOLED touchscreen with 1920 x 1200 resolution and 161 ppi pixel density provides sharp, detailed visuals well-suited to productivity and content work
  • A stylus is included in the box, making the 2-in-1 touchscreen immediately usable for note-taking or sketching without additional purchases
  • The NVMe PCIe 4.0 SSD with 1 TB of storage offers fast data access and ample space for large files and applications
  • Wi-Fi 6 support ensures faster and more reliable wireless connectivity in compatible network environments
  • The fingerprint scanner enables quick and secure login without requiring a password
  • Two USB 3.2 Gen 2 Type-C ports alongside two USB 3.2 Gen 1 Type-A ports provide a practical mix of modern and legacy connectivity, complemented by an external memory card slot
Cons
  • The display refresh rate is limited to 60Hz, which may feel less fluid for users accustomed to higher refresh rate screens
  • At 1,500 g and 17 mm thick, the device is not among the lightest or slimmest options in the 2-in-1 productivity category
  • The HDMI output is version 1.4 only, restricting maximum external display resolution and refresh rate
  • There is no Thunderbolt or USB 4 port, limiting high-bandwidth peripheral and external display options
  • The display lacks an anti-reflection coating, which may affect usability in bright or outdoor environments
  • The maximum memory is capped at 16 GB with no support for ECC, leaving no headroom for future RAM upgrades
Who is this for?

This 2-in-1 laptop is well-suited to office professionals and students who need a versatile everyday machine capable of handling productivity workloads and light creative tasks. The OLED touchscreen combined with the included stylus makes it a practical choice for anyone who regularly annotates documents, sketches ideas, or consumes visual content. The 1 TB NVMe SSD and 16 GB of DDR5 RAM ensure responsive multitasking across typical business and academic workflows, while Wi-Fi 6 support and a solid port selection make it easy to integrate into modern home office or campus environments.

Who is this NOT for?

Users who require demanding graphics workloads will find this device limited, as the integrated UHD Graphics 770 does not support ray tracing or DLSS, ruling out serious gaming or GPU-accelerated creative rendering. The 60Hz display refresh rate and the absence of Thunderbolt or USB 4 ports make it a poor fit for users who depend on high-bandwidth peripherals or fast external display setups. Additionally, those who need extensive memory headroom for data-heavy applications such as large dataset processing or virtual machine hosting will be constrained by the 16 GB memory ceiling with no upgrade path.
