The issue you're facing with your Microsoft Bluetooth Mouse 5000 losing functions like wheel scrolling after returning from Sleep or Hibernation can be frustrating. Here are some troubleshooting steps you can try to resolve this problem: 1. Update Bluetooth Drivers: - Make sure you have the latest Bluetooth drivers installed for your Dell Studio 1730. You can download the latest drivers from the Dell website to ensure compatibility with Windows 7 Build 7077. 2. Power Management Settings: - Sometimes power management settings can cause issues with Bluetooth devices.

BIOS Update: - Ensure that your laptop's BIOS is up to date. Sometimes BIOS updates address compatibility issues with hardware devices. 4. Check Bluetooth Services: - Ensure that Bluetooth services are set to start automatically. - Press Win + R, type services.msc, and press Enter. - Look for Bluetooth related services (like Bluetooth Support Service) and ensure they are set to start automatically. 5. Disable Fast Startup: - Fast Startup can sometimes cause issues with hardware devices. Try disabling it to see if it resolves the problem. - Go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable. Uncheck "Turn on fast startup (recommended)." 6. Check for Windows Updates: - Make sure your Windows 7 installation is up to date with the latest Windows updates. Sometimes updates include fixes for known issues. 7. Alternative Solution: - As a temporary solution, you could try setting your computer to not go to sleep or hibernate automatically. This way, you wouldn't face the issue until a permanent solution is found.
