Problem: Acer Aspire A515-54G Bluetooth Quit Working

Explanation: A recent driver update available through Microsoft Windows Update does not seem to support this hardware well.

Solution: Rollback the current driver to the previous driver.

Step 1: Search Windows for Device Manager

2: Select the bluetooth adapter under “bluetooth”

3: Double-click the device to see properties

4: Click the “driver” tab in the properties window

5: Click “Roll Back Driver” and follow the on-screen instructions

After rolling back, you may need to restart. I suggest a “cold” restart. Click the Windows button and hold down the SHIFT key while you click on “Shutdown” or “Restart.”

This should resolve this issue on this particular laptop model.
