HP Envy 16 Intel Core Ultra 7 155H Bluetooth 5.3 Not Pairing Fix Windows 11

Bluetooth on your HP Envy 16 Intel Core Ultra 7 155H is not pairing with headphones, mice, keyboards, or other devices – the Bluetooth scan finds no devices, pairing attempts fail with error messages, or previously paired devices will not reconnect. Intel Bluetooth driver updates and Windows Bluetooth service restart restore Bluetooth pairing on the HP Envy 16.

This guide covers Intel Bluetooth driver updates, Bluetooth service troubleshooting, and pairing reset for the HP Envy 16 Intel Core Ultra 7 155H in Windows 11.

“HP Envy 16 Core Ultra 7 Bluetooth stopped finding devices after Windows update. Intel Wireless driver update via HP Support Assistant fixed it. Also had to restart Bluetooth Support Service in services.msc. Headphones and mouse pairing worked again after both steps.” – Khairunisa, digital marketing manager from Damansara

Why Bluetooth Does Not Work on HP Envy 16 Intel Core Ultra 7 155H

Intel WiFi 6E AX211 in the HP Envy 16 provides both WiFi 6E and Bluetooth 5.3 functionality through the same M.2 wireless module and driver package. Windows Update can replace the HP-qualified Intel Wireless driver with an older generic Intel Wireless driver version that may have different Bluetooth 5.3 support or Bluetooth antenna configuration for the HP Envy 16 chassis. Additionally, the Bluetooth Support Service (bthserv) can enter a stopped state after certain Windows Update sequences, leaving the Bluetooth adapter hardware visible in Device Manager but unable to enumerate nearby Bluetooth devices or process pairing requests.

• Intel WiFi/Bluetooth driver downgraded or replaced by Windows Update
• Bluetooth Support Service (bthserv) stopped – Bluetooth hardware not processing scan or pair requests
• Pairing database corrupted – device shows paired but cannot reconnect, blocking new pairs
• Bluetooth adapter power saving turning off adapter between Bluetooth events

Fix 1 – Update Intel Wireless Driver via HP Support Assistant

Open HP Support Assistant and install Intel WiFi 6E and Intel Wireless Bluetooth driver updates. Both WiFi and Bluetooth components update together as they share the AX211 hardware module. Restart. After restart, toggle Bluetooth Off and On in Settings – Bluetooth and devices. Place the Bluetooth device in pairing mode and click Add device in Windows Bluetooth settings. The HP-qualified Intel Wireless driver package for the Envy 16 Core Ultra 7 155H includes the correct Bluetooth 5.3 firmware file and antenna configuration for the HP Envy 16 chassis, which may differ from the generic driver that Windows Update installs and affect Bluetooth scan sensitivity and pairing reliability.

Fix 2 – Restart Bluetooth Support Service

Press Windows+R and type services.msc. Find Bluetooth Support Service in the list. Check if Status shows Running. If Stopped, right-click – Start. If Running but Bluetooth still not working, right-click – Restart. Also check these dependent services are running: Bluetooth Audio Gateway Service, Bluetooth User Support Service. After starting Bluetooth Support Service, go to Settings – Bluetooth and devices and toggle Bluetooth Off and On. The Bluetooth Support Service manages the Bluetooth device registry, handles pairing authentication, and coordinates between the Intel Bluetooth hardware and Windows application-layer Bluetooth APIs – a stopped service prevents any Bluetooth device from pairing or connecting on the HP Envy 16 regardless of driver state.

Delete and Re-Pair Bluetooth Device

In Settings – Bluetooth and devices, click the three dots next to a problematic previously-paired device and select Remove device. After removal, put the Bluetooth device back into pairing mode (device-specific: for most headphones, hold power button 5-7 seconds until LED flashes rapidly). Click Add device – Bluetooth in Windows Settings and select the device from the scan list. Fresh pairing from scratch resolves corrupted pairing key issues where the security credentials stored for a previously paired device no longer match the device’s current state – this mismatch causes the device to show as paired but fail to connect on the HP Envy 16 Intel Core Ultra 7 155H Bluetooth system.

Fix 3 – Disable Bluetooth Adapter Power Management

Open Device Manager – Bluetooth – Intel Wireless Bluetooth – Properties – Power Management tab. Uncheck Allow the computer to turn off this device to save power. After unchecking, the Intel Bluetooth adapter stays fully powered between Bluetooth events rather than entering a low-power state. Bluetooth adapter power saving can cause the adapter to miss incoming Bluetooth connection requests from devices attempting to reconnect (headphones, mice) because the adapter is in a low-power sleep state rather than actively scanning. Disabling power management ensures the adapter is always available to receive reconnection requests from previously paired Bluetooth 5.3 devices without requiring the user to manually trigger Bluetooth re-scan on the HP Envy 16.

Fix 4 – Reset Bluetooth Adapter in Device Manager

Open Device Manager – Bluetooth – right-click Intel Wireless Bluetooth – Disable device. Wait 10 seconds. Right-click again – Enable device. This hardware-level reset clears the Bluetooth adapter state including any scan or pairing process that may have become stuck in an error state. After enabling, Windows re-initializes the Intel AX211 Bluetooth component and the Bluetooth adapter performs a clean startup scan, making nearby Bluetooth devices visible for pairing. If disabling and re-enabling in Device Manager does not work, try Uninstall device (do not delete driver) and restart – Windows automatically reinstalls the Intel Bluetooth driver component from the HP driver package on next boot for the HP Envy 16 Core Ultra 7 155H.

Frequently Asked Questions
