: ASUS does not list official Windows 10 Bluetooth drivers on their K53SD Support Page or other K53S variants.

The ASUS K53S is a testament to longevity, but its Bluetooth driver on Windows 10 can be a headache. While ASUS abandoned official support, the solutions above—especially the manual “Have Disk” method for Atheros chips or the USB dongle workaround—restore full Bluetooth functionality. Start with Windows Update, then try the Windows 8.1 compatibility driver, and if all else fails, spend a few dollars on a USB dongle. Your K53S can still connect wirelessly to modern devices without issue.
