Everyday laptop with touch display

The Lenovo IdeaPad 3 81X800ENUS is a 15.6-inch notebook built around an Intel Core i3-1115G4 dual-core processor and 8 GB of DDR4 memory. A 256 GB PCIe SSD handles storage while Intel UHD Graphics shares system memory. The HD touchscreen runs at 1366 x 768 on a TN panel rated at 220 nits with an anti-glare coating. Windows 11 in S mode ships pre-installed.

Suits students and office workers needing pen input

This model fits buyers who want a touchscreen for note-taking or light creative tasks on a tight budget. The dual-core chip and integrated graphics limit heavy multitasking, video editing or modern gaming. Users who need a higher-resolution IPS panel, discrete graphics or more than 8 GB of memory should look at other configurations.

Check your software and peripheral needs

Windows 11 in S mode only runs apps from the Microsoft Store unless you switch out of S mode, which is a one-way change. The laptop provides one USB 2.0 port, two USB 3.2 Gen 1 ports and HDMI for external displays. Wireless uses Wi-Fi 5 and Bluetooth 5.0. The single memory slot is already populated so RAM cannot be expanded.

Questions about this item

Does the 81X800ENUS need any external peripherals to operate out of the box?

No, the 15.6" touchscreen, keyboard, trackpad, Wi-Fi 5 and Bluetooth 5.0 are all built in, so the laptop works immediately without extra hardware.

Can I keep using my older USB 2.0 flash drives with the two USB 3.2 Gen 1 ports on this IdeaPad 3?

Yes, the USB 3.2 Gen 1 ports are backward compatible, so USB 2.0 drives will function at their usual speed.

How can I confirm the Intel UHD Graphics are active after the first boot?

Open Device Manager, expand Display adapters and verify Intel UHD Graphics appears without a warning icon.
