❌ Windows Update pushes wrong Wi-Fi driver (Intel vs. MediaTek – check your hardware ID). ❌ Some drivers require a specific install order (chipset → graphics → audio → others). ❌ No Linux driver support for fingerprint sensor (if you dual-boot). Final Verdict 4.2/5 – HP does an excellent job maintaining drivers for the 840 G9, but don’t rely on Windows Update alone. Always download chipset, graphics, and BIOS from HP manually. If you face peripheral or power issues after a clean OS install, those three drivers are almost always the fix. Pro tip: Create a folder with the latest chipset, graphics, Thunderbolt, and BIOS drivers on a USB stick before reinstalling Windows – it saves hours of troubleshooting.
