Choose drivers for the IdeaPad Slim 1-14AST-05

Confirm the full Slim 1-14AST-05 model before choosing a download. Similar IdeaPad names are not enough to match a package; use the Lenovo model identification guide if you are unsure.

Windows 10 wireless and Bluetooth packages

Lenovo lists DS541831 for WLAN and DS541828 for Bluetooth as separate Realtek/Liteon packages for Windows 10 64-bit, including this exact model. Match the installed adapter before selecting either package. For the adapter checks and the difference between Wi-Fi and Bluetooth drivers, see the wireless driver selection guide.

Some general-purpose utilities in the archive below list Windows 11. Those utility labels do not establish Windows 11 driver support for this laptop or extend the operating systems listed for its individual drivers. Check each package’s supported models and operating systems using the Lenovo download-page guide.

Storage configuration and network hardware

The Lenovo specifications for Slim 1-14AST-05 describe alternative storage configurations: onboard eMMC or an M.2 2242 PCIe NVMe SSD, rather than both together. Check which configuration you have before considering the eMMC entry below; an SSD configuration is not a reason to install an eMMC driver. Lenovo also lists no onboard Ethernet, so a separate USB network adapter needs a driver matched to that adapter.
