15.3" WUXGA touch laptop for everyday work

The Lenovo IdeaPad Slim 3 ships new in Luna Grey with a 15.3 inch WUXGA IPS touch display at 1920 x 1200 resolution. An AMD Ryzen 5 8540U processor runs at 3.20 GHz up to 4.90 GHz alongside integrated AMD Radeon 740M graphics. The system includes 16 GB DDR5 memory and a 512 GB PCIe NVMe SSD with Windows 11 Home preinstalled.

Backlit keyboard, IR camera

A white backlit keyboard with numeric keypad helps typing in low light. The hybrid RGB 1080p FHD infrared camera supports Windows Hello and has a physical privacy shutter. Dual array microphones and Dolby Audio on 2 x 2W speakers handle calls. Wi-Fi 6 and Bluetooth 5.3 provide wireless connectivity.

Standard ports and soldered memory limit later

Ports include USB-C with power delivery 3.0 and DisplayPort 1.2, two USB-A 5Gbps, HDMI 1.4, headphone combo and micro SD reader. Memory is soldered to the board so the 16 GB cannot be upgraded. The 60 Wh battery is internal and the SSD uses an M.2 slot that may require disassembly for replacement.

Questions about this item

Can the 16 GB DDR5 memory be upgraded later?

The system supports up to 32 GB DDR5 RAM, so an additional module can be installed if a free slot is available.

What thermal limit appears first during long workloads on the Ryzen 5 8540U?

The processor can boost to 4.90 GHz, but sustained clocks will be limited by the 60 Wh battery and slim cooling design.

How loud does the fan get and how hot does the chassis feel after hours of use?

The 15.3 inch chassis with 60 Wh battery relies on a single fan; expect audible spin under load and warm palm rests near the rear vents.
