HP Recommended
Product: HP Pavilion Plus 14 inch Laptop PC 14-ew0000 (7X843AV)

Hello. I have a HP Pavilion Plus 14-ew0xxx, running Windows 11 25H2.

The internal Bluetooth started failing persistently. Bluetooth connects, but when I play audio over Bluetooth it disconnects after a few minutes. It happened while using an Realme buds t310 as Bluetooth audio output, but the issue seems to be with the internal Bluetooth adapter, not the external device.

Observed symptoms:

- Device Manager showed MediaTek Bluetooth Adapter with Code 43 : “Windows has stopped this device because it has reported problems.”
- It later appeared as Generic Bluetooth Adapter.
- Sometimes Bluetooth disappears from Windows Settings or appears disabled even when the toggle is on.
- PowerShell showed the adapter as not present/phantom:
CM_PROB_PHANTOM
Present: False
- Wi-Fi works normally.

Steps already tried:

- Normal restart.
- Full shutdown / power drain by holding the power button.
- Uninstalling and reinstalling the Bluetooth device from Device Manager.
- Downloaded the official HP MediaTek Bluetooth driver package sp171518.
- Forced driver installation with:
pnputil /add-driver "C:\SWSetup\sp171518\*.inf" /subdirs /install

- Ran:
pnputil /scan-devices
- Checked Bluetooth devices with:
Get-PnpDevice -Class Bluetooth

The driver appears to install, but the problem returns and persists when Bluetooth audio is used. Should I install an additional chipset, WLAN, BIOS/firmware driver, or does this point to a failing internal Bluetooth module?

Thank you.
