The Advanced Configuration and Power Interface (ACPI) handles hardware discovery and power management. When Windows displays ACPI\TOS6205 , it means the system detects the physical Toshiba Bluetooth module but cannot communicate with it due to a missing software bridge.
Common symptom : Bluetooth shows “Device cannot start (Code 10)” or is missing entirely, but Wi-Fi works fine. A yellow exclamation mark will also appear in

The core of the problem lies in the , identified by the hardware ID TOS6205 . Unlike standard Bluetooth chips from Broadcom or Intel, Toshiba often employed custom components from vendors like Foxconn or Lite-On, branded under their own TOS prefix. These devices were designed to interface with the system’s ACPI, a power management standard that controls everything from battery life to device wake functions. When a user installs Windows 7, 8, or 10 on the C660, the OS may detect the Bluetooth radio but fail to assign it the correct resources (IRQ, memory address) because the ACPI BIOS does not properly report the device’s capabilities. The result is a yellow exclamation mark in Device Manager, with an error code (often 10 or 43), rendering the Bluetooth adapter inert.
