  • Drivers for function keys and proprietary Sony utilities can be frustrating to locate.

6. Handling Common Issues

  • Missing chipset driver: System may show unknown PCI devices. Install Intel INF package and reboot.
  • Graphics problems (black screen, low resolution): Confirm use of Intel HD driver; if discrete GPU present, ensure switchable graphics driver stack is installed correctly.
  • Wireless not detected: Check vendor wireless card model; install appropriate Broadcom/Atheros/Intel driver. If WLAN appears disabled by physical switch or Fn key, ensure Vaio Event Service is installed.
  • Function keys not working: Install Vaio Event Service and Hotkey utilities from Sony.
  • Audio crackle or no sound: Install Realtek HD Audio driver and set correct default playback device. Update codec if needed.
  • Bluetooth pairing failures: Use vendor Bluetooth stack and ensure Windows Bluetooth Support Service is running.
  • Blue Screens (BSOD): Note stop codes; ensure storage drivers (IRST/AHCI) match BIOS settings; update chipset, BIOS, and drivers.
  • Driver signature enforcement: Windows 7 x64 enforces driver signatures; obtain signed drivers or use test mode only if necessary (not recommended for long-term security).
