Thin and Light Laptop

The Lenovo IdeaPad Slim 3 in Cosmic Blue ships with Windows 11 Home and a 15.3 inch WUXGA IPS panel at 1920 x 1200 resolution. An AMD Ryzen 7 8840HS eight-core processor pairs with 16 GB of DDR5 5600 memory and a 512 GB M.2 2242 SSD. Integrated AMD Radeon 780M graphics share system memory for everyday visual tasks. Wi-Fi 6E and Bluetooth 5.3 handle wireless connectivity.

Sustained Load Behaviour

The 8-core Ryzen 7 8840HS offers 8 MB of L2 cache and 16 MB of L3 cache to maintain throughput during extended workloads. Shared video memory means graphics performance scales with the dual-channel DDR5 configuration of 8 GB onboard plus 8 GB in the single slot. The 300-nit non-touch display remains legible during long sessions. Two 2 W speakers provide basic audio output without external devices.

Setup Checks Before Ordering

Memory uses the sole SODIMM slot, so no further RAM upgrades are possible after purchase. Storage uses the M.2 2242 form factor; verify that any replacement drive matches this length. The port selection includes one USB 3.2 Gen 1 Type-C, two USB 3.2 Gen 1 Type-A, one HDMI and a headphone/microphone combo jack. A 720p webcam with privacy shutter is built in for video calls.
