Lenovo IdeaPad 5i 2-in-1 Gen 9 14" Intel Core 7 150U 1.8GHz / 16GB RAM / 1TB SSD

Manufacturer: Lenovo

The Lenovo IdeaPad 5i Gen 9 is a 14-inch laptop that combines a touch-enabled OLED display with a resolution of 1920 x 1200 px and a brightness of 400 nits, offering a notably vivid screen for a device in this form factor. It includes 16GB of DDR5 RAM, a 1TB NVMe SSD, a stylus, and a fingerprint scanner, all within a chassis measuring 313 mm wide, 227 mm deep, and 17 mm thick at a weight of 1,500 g. A three-year warranty is also included.

Under the hood, the laptop runs a 10 nm CPU using big.LITTLE technology, clocking two cores at 1.8 GHz and eight at 1.2 GHz with a turbo speed of 5.4 GHz across 12 threads. Graphics are managed by the integrated Intel Iris Xe Graphics G7 with 96 execution units, supporting OpenGL 4.6 and OpenCL 3. Connectivity includes Wi-Fi 6E, Bluetooth 5.1, two USB 3.2 Gen 2 Type-C ports, two USB 3.2 Gen 1 Type-A ports, one HDMI 1.4 output, and an external memory slot. The system also has stereo speakers, a 3.5 mm audio jack, a dual-microphone setup, a front camera, and AirPlay support, while sleep-and-charge USB and MagSafe adapter are not included.

Pros
  • The 14-inch OLED/AMOLED touch screen delivers a resolution of 1920 x 1200 px at 400 nits brightness, offering a noticeably vivid display for a laptop in this size class
  • A stylus is included in the box, adding handwriting and annotation capability without requiring an additional purchase
  • The three-year warranty provides a longer coverage period than the one-year terms common among competing laptops
  • At 1,500 g and 17 mm thick, the chassis is relatively slim and light for everyday carrying
  • A fingerprint scanner enables quick biometric login without relying on a password
  • Wi-Fi 6E support ensures compatibility with the latest wireless networks for faster and lower-latency connections
Cons
  • The keyboard does not include backlighting, which limits usability in dim environments
  • There is no RJ45 Ethernet port, so a wired network connection requires an external adapter
  • The HDMI output is limited to version 1.4, which restricts the resolution and refresh rate available on external displays
  • No sleep-and-charge USB ports are present, meaning connected devices cannot charge when the laptop is powered off or sleeping
  • Bluetooth 5.1 is an older version relative to more recent implementations found on newer devices, though this remains the only version available here
  • The maximum supported RAM speed is listed as 6400 MHz, while the installed DDR5 memory runs at 5200 MHz, indicating the configuration does not fully utilize the platform ceiling
Who is this for?

The Lenovo IdeaPad 5i Gen 9 is well-suited to users who value a vivid touch-enabled OLED display for content consumption, note-taking with the included stylus, or creative tasks that benefit from accurate color rendering at 400 nits. Its slim 17 mm profile and 1,500 g weight make it practical for users who carry their laptop daily, and the three-year warranty adds reassurance for those who want longer-term coverage without additional purchases. Wi-Fi 6E support and a fingerprint scanner further strengthen its appeal for mobile professionals who need fast wireless connectivity and convenient biometric login.

Who is this NOT for?

Users who depend on wired Ethernet or high-bandwidth external display output will find the absence of an RJ45 port and the HDMI 1.4 limitation genuinely restrictive in desk-based or multi-monitor setups. The integrated Iris Xe Graphics G7 makes this a poor match for anyone running GPU-intensive workloads such as gaming, 3D rendering, or video editing, and the lack of a backlit keyboard will frustrate those who frequently work in low-light environments. Users who require sleep-and-charge USB functionality for overnight peripheral charging will also need to look elsewhere.
