Sorry to read about the troubles that you're having with the laptop's data transfer. Here are a few steps you can try to troubleshoot the problem:
1. Update BIOS and Drivers: Please make sure that your system has the latest BIOS and driver updates via Lenovo Vantage app.
2. Update Windows: Check if there are any pending Windows Updates that needs to be installed.
3. Check USB Ports: Try using a different USB port on your Lenovo laptop. Sometimes, certain ports may have different performance characteristics.
4. Performance Settings: Make sure your laptop is set to high-performance mode. You can adjust this in the power settings.
5. Test with Another Device: If possible, test the SD card and reader on another device to ensure they are functioning correctly.
Let us know how it goes.
