The Dynabook Bluetooth ACPI Control Driver is a Windows driver associated with Bluetooth functionality on Dynabook (formerly Toshiba) laptops and other devices. It ensures that the Bluetooth hardware on your system (e.g., a built-in Bluetooth adapter) works correctly with the operating system, enabling Bluetooth connectivity for wireless devices like headphones, speakers, keyboards, mice, and more.

What is the Dynabook Bluetooth ACPI Control Driver?

• ACPI stands for Advanced Configuration and Power Interface, which is a standard for power management and device configuration.
• The Dynabook Bluetooth ACPI Control Driver specifically controls Bluetooth power management and ACPI features, allowing the system to manage Bluetooth resources efficiently (e.g., enabling/disabling Bluetooth based on system states like sleep or hibernation).

How to Install the Dynabook Bluetooth ACPI Control Driver

1. Automatic Installation via Windows Update

Windows often automatically installs drivers for most hardware, including Bluetooth adapters, through Windows Update. Here's how to check and install any available updates:

• Step 1: Open the Settings app by pressing Win + I on your keyboard.
• Step 2: Go to Update & Security > Windows Update.
• Step 3: Click on Check for Updates and wait for Windows to search for updates.
• If any Bluetooth drivers are found, Windows will automatically download and install them. You may need to restart your computer after the installation is complete.

2. Manual Installation of the Dynabook Bluetooth ACPI Control Driver

If the driver is not automatically installed via Windows Update, you can manually download and install the driver from the Dynabook (Toshiba) website or use the Device Manager to install it.

Option A: Download from Dynabook Support Website

1. Go to the Dynabook support website:

   • Visit the official Dynabook support page (formerly Toshiba).
   • Search for your specific model of laptop or device by entering the product name or model number.

2. Download the Bluetooth Driver:

   • Once on the support page for your device, navigate to the Downloads or Drivers section.
   • Look for the Bluetooth driver or Bluetooth ACPI control driver specific to your version of Windows (e.g., Windows 10, Windows 11).

3. Install the Driver:

   • Download the driver file (usually in .exe format).
   • Once the download is complete, run the installer and follow the on-screen instructions to install the driver.
   • Restart your computer to complete the installation.

Option B: Install Using Device Manager

If you've already downloaded the driver manually or if Windows has detected the Bluetooth adapter but is not functioning properly, you can try to update or install the driver via Device Manager.

1. Open Device Manager:

   • Right-click on the Start menu and select Device Manager.
   • Alternatively, press Win + X and choose Device Manager from the list.

2. Find Bluetooth Devices:

   • Expand the Bluetooth section in Device Manager.
   • Look for an entry that says Bluetooth ACPI or something similar related to your Bluetooth hardware (it may appear under a subcategory such as "Bluetooth Radios").

3. Update Driver:

   • Right-click on the Bluetooth ACPI device and select Update Driver.
   • Choose Search automatically for updated driver software to allow Windows to search for the latest version of the driver.
   • If Windows finds an updated version, it will install it automatically.

4. Manually Install the Driver (if the automatic search fails):

   • Browse my computer for driver software.
   • Navigate to the location where the driver is stored, select the appropriate folder, and click Next to install the driver.
   • Restart your computer when prompted.

3. Verify the Bluetooth Device is Working

After installing or updating the driver, ensure that Bluetooth is functioning correctly:

1. Check Bluetooth Settings:

   • Press Win + I to open Settings.
   • Go to Devices > Bluetooth & other devices.
   • Check if Bluetooth is enabled and if your Bluetooth devices are listed.

2. Test Bluetooth Connectivity:

   • Try pairing a Bluetooth device, such as a headset or keyboard, to see if the connection is stable and the device is functioning properly.

3. Device Manager:

   • Open Device Manager again and verify that the Bluetooth ACPI Control driver is listed without any warning symbols (yellow triangles) next to it.

Troubleshooting

If Bluetooth is not working after installing the driver, here are some things you can try:

1. Uninstall and Reinstall the Driver:

   • In Device Manager, right-click the Bluetooth ACPI device and select Uninstall device.
   • Restart your computer, and Windows should automatically reinstall the necessary Bluetooth drivers.

2. Enable Bluetooth in BIOS/UEFI:

3. Check Bluetooth Settings:

   • Make sure Bluetooth is enabled in Windows. Go to Settings > Devices > Bluetooth & other devices and toggle Bluetooth to On.

4. Update Windows:

   • Make sure that your system is up to date with the latest Windows updates, which might include critical Bluetooth updates.

5. Check for Hardware Issues:

   • If the problem persists, there might be a hardware issue with the Bluetooth adapter. You can test the hardware by connecting to another system or using a USB Bluetooth adapter as a workaround.

Conclusion

The Dynabook Bluetooth ACPI Control Driver is essential for ensuring proper Bluetooth functionality and power management on Dynabook laptops or devices. By following the steps above, you can either let Windows automatically update your driver or manually download and install the correct version from the Dynabook website.

If you continue to have issues after installation, consider troubleshooting by checking the system settings, updating Windows, or using the Device Manager to uninstall and reinstall the driver.
