All-in-One for Home and Study

The Lenovo C40-05 is a 21.5 inch all-in-one desktop built for home office and student use. It runs Windows 10 Pro on an AMD A6-6310 quad-core processor clocked at 1.8 GHz with a boost up to 2.4 GHz. The system includes 8 GB of DDR3 memory and a 256 GB SSD for the operating system and files.

Touchscreen Display and Integrated Connectivity

The Full HD LED panel offers 1920 by 1080 resolution with ten-point touch input for direct screen interaction. A built-in DVD writer handles optical media, while Gigabit Ethernet, 802.11ac Wi-Fi and Bluetooth 4.0 provide wired and wireless networking. The 110 W power supply runs the entire unit without an external brick.

Entry-Level Graphics and Memory Limits

The discrete AMD Radeon R5 M230 with 2 GB video memory suits basic multimedia and light productivity but cannot drive modern 3D workloads. The 8 GB DDR3 configuration is not expandable beyond the installed capacity, limiting multitasking headroom. Buyers needing discrete GPU upgrades or higher memory ceilings should consider a tower platform.

Questions sur cet article

What does the 802.11ac wireless interface cap in practice?

The 802.11ac Wi-Fi supports up to gigabit-class throughput on a 5 GHz band, but real-world speed depends on router capability, channel width and local interference.

What physical space does the 21.5 inch all-in-one need on a desk?

The unit integrates the 1920 x 1080 touchscreen, mainboard and 110 W power supply in a single chassis, so only the footprint of the stand and clearance for rear ports are required.

How is Windows 10 Pro 64-bit installed on the 256 GB SSD, and what step do people miss?

The OS ships pre-installed and activated; the step users often skip is running Windows Update and Lenovo System Update immediately after first boot to install current drivers and security patches.
