ASUS A400UQ drivers

This page contains 91 official source records for ASUS A400UQ. Select the exact hardware variant and operating system below before choosing a package. These are release records, including retained versions, not a list of mandatory installations.

Recorded systems and scope

Only the listed systems have local records. Older Windows entries are historical download records, not a promise of current OS support. “Others” or an empty bitness field does not imply Windows compatibility.

What is available for this model

Vendors explicitly named in package titles include Realtek, Intel, Qualcomm / Atheros, Conexant, nVidia, NVidia. If more than one network package is listed, check the installed adapter vendor and hardware IDs; do not install every alternative.

Official hardware / BIOS variants recorded here: K401UQ, K401UQK. Follow the exact variant selector below; this page does not choose the nearest suffix.

Before installing

  1. Confirm your complete model and read the system information from your device.
  2. Select the actual system and bitness below, then compare category, version and release date with the package notes.
  3. Use the official download button for the matching package. Follow the installation checks and the package’s own instructions.
  4. Keep a record of what changed and test the affected function after any installer-requested restart.

Stop if your full model, hardware identity or operating system differs, or the installer rejects the package. Missing records do not establish that no driver exists. BIOS files require the separate power, recovery-key and exact-model checks.
