Hi Edmond,
It would be great if you can provide more information regarding this issue. Please answer these questions:
1) Did you install the latest Windows 8.1 compatible Bluetooth drivers from the Lenovo website? If yes, what is its version?
2) Did you try uninstalling and then reinstalling the latest drivers and check if that resolves the issue?
3) Do you have any third party security program installed on the computer?
I would suggest you to try the following methods and let’s know the results.
Method 1: Run the Hardware Troubleshooter
The Hardware Troubleshooter is an automated tool which checks the hardware on the computer for any known issues and provides the details on how to fix them. Follow these steps to run the troubleshooter.
a) Press “Windows Logo” + “W” keys from the keyboard.
b) Type “Troubleshooting” in the search bar and press “Enter”.
c) In the “Troubleshooting” window, click on “View All” on the left pane.
d) Click on “Hardware and Devices”.
e) Click on “Advanced” and then click on “Run as Administrator”.
f) Click “Next” and follow the on-screen instructions to complete the troubleshooting process.
Please check the troubleshooting report and let’s know the details. You may also try the suggestions given by the troubleshooter and check if that helps. You may also try uninstalling and reinstalling the Bluetooth drivers and check if that resolves the issue.
Method 2: Uninstall and Reinstall the Bluetooth Drivers
Follow these steps to uninstall and reinstall the driver:
Step 1: Uninstall the Bluetooth Device Drivers
a) Press “Windows Logo” + “X” keys on the keyboard.
b) Click on “Device Manager” from that list.
c) Search for the Bluetooth device from the device list, right click on it and then select “Uninstall”. On the un-installation window, if you have an option: “Delete the driver software for this device” you may select that and then remove the corrupted drivers from the computer.
d) Follow the on-screen instructions to complete it and the restart the computer if prompted.
After the restart, you may again open the Device Manager and then click on the “Scan for hardware changes” button at the top of the Device Manager window and check if Windows 8.1 detects the Bluetooth device and installs an appropriate driver for it automatically. If that happens, then check if it resolves the issue. If the issue persists, then go with the next step.
Step 2: Check the Windows updates for any latest driver updates.
Check in Windows updates if any driver updates are available. If so, install the same and check if it helps.
a) Press “Windows Logo” + “W” keys from the keyboard.
b) Type “Updates” in the search bar and click on the icon “Windows Update” from the search result.
c) On the “Windows Update” window, click on the link: “Check for updates” from the left hand side of the window to receive a fresh list of updates.
d) If the updates are available, then install all the updates listed there.
If Windows Update does not offer the latest Windows 8.1 driver, then try the next step.
Step 3: Update Driver Software from the Manufacturer’s website:
Go to the Lenovo website and search for the latest Windows 8.1 drivers available for the device model and then install it by following the instructions given in the website. You may click on this link to download the latest drivers for the Bluetooth device:
