Slim 3i 15.3 WUXGA Touchscreen Copilot+

The Lenovo IdeaPad Slim 3i is a lightweight laptop built for mobile productivity. It runs Windows 11 Home on an Intel Core Ultra 7 355 processor with 16 GB of memory and a 1 TB M.2 2242 SSD. The 15.3 inch WUXGA IPS panel supports touch input and a 16:10 aspect ratio.

120Hz touchscreen and Dolby Audio speakers

A 120 Hz refresh rate makes scrolling and video playback smoother on the touchscreen. The display reaches 400 nits brightness and carries TÜV Low Blue Light certification for reduced eye strain. Dual speakers tuned with Dolby Audio deliver clearer sound for media and calls.

Suits mobile workers wanting touch and long battery

This configuration fits users who value a large touch display, integrated AI features and all-day battery life in a thin chassis. Buyers who need discrete graphics for heavy rendering or gaming should look elsewhere. Those requiring more than 16 GB of memory or multiple storage drives will need a different model.

Questions about this item

Can the 16 GB memory module be upgraded later?

The memory specification lists 16 GB x 1 with no mention of additional slots, so the installed module is the only one present.

What limits sustained performance first on the Intel Core Ultra 7 355?

The processor relies on integrated graphics, so thermal headroom for the combined CPU and GPU workload is the first constraint under continuous load.

How loud or hot does the laptop get when running all day?

The thin-and-light chassis uses passive cooling for the integrated graphics, so surface temperatures rise and fan noise increases during extended sessions.
