  4. Lenovo IdeaCentre B320 Bluetooth Issues in Windows 10

We were recently called upon to repair a fault on a Lenovo IdeaCentre B320 All-in-One Desktop Computer. After upgrading from Windows 7 to 10, the supplied keyboard and mouse could no longer be used on the Windows 10 login screen. The keyboard and mouse (which are Bluetooth) no longer worked at login. One work around was to use the onscreen keyboard facility to enter the password. However, after the most recent Windows 10 update (version 1703 – Creators Update), the touch screen had also stopped working so now they were well and truly stuck. Computer Repair Man to the rescue, we set about finding a solution!

How to Repair Bluetooth on a Lenovo IdeaCentre B320 in Windows 10

After a little research, we found a fix. It turns out the Bluetooth drivers are not being loaded until after logon. In fact, Bluetooth devices don’t even show in Device Manager at all, although Bluetooth is working after logon. If you are having this same problem, please try the following steps to resolve.

1. In Control Panel->Programs & Features (WIN+R, appwiz.cpl), uninstall all references to Bluetooth, Broadcom and Hotkey Driver. If they fail to uninstall, you may need to use an alternative uninstaller (examples here 😕http://www.techradar.com/news/the-best-free-software-uninstaller).
2. Download & install the Broadcom Bluetooth 4.0 Driver for Windows 10 here : http://support.lenovo.com/gb/en/downloads/ds031759
3. Reboot your computer.
4. Download & install Lenovo Application Interface Driver for Windows 10 here : http://pcsupport.lenovo.com/gb/en/downloads/ds103153
5. Reboot your computer.

After Installing the drivers, you should have device manager looking something like this :

Hopefully you can now use the official Lenovo Bluetooth keyboard & mouse on your Lenovo IdeaCentre B320 to login to Windows 10.


If you receive errors when trying to install the drivers or application in steps 2 and 4, we did too the first time around. It maybe that you haven’t removed all the required software in step 1, look carefully for a Hotkey driver in the list and ensure that is removed. Make sure you have also removed Lenovo Bluetooth with Enhanced Data Rate Software and try again. If the Bluetooth drivers aren’t removed, you might not be able to install the new drivers in Step 2. If these are definitely gone, try the following to install the updated Bluetooth drivers.


  1. 1. Locate the folder C:\SWTOOLS\WIN\Bluetooth
  2. 2. Navigate into the folder Win32 for 32 bit Windows 10 and Win64 for 64 bit Windows 10.
  3. 3. Locate the application “Inst.exe” (it will just say “Inst” if you have file extensions hidden) and run it.
  4. 4. Now try again to install Lenovo Application Interface Driver for Windows 10 as detailed in Step 4 above.

Hopefully this will be working for you now. If you need any help, have any further information or just want to share that it worked for you, please leave a comment below.
