If your Lenovo B50 laptop is running incredibly slow, there are a few steps you can take to try and improve its performance. First, try restarting the laptop to see if that helps. If the issue persists, you can try freeing up disk space by deleting unnecessary files and programs, running a virus scan to check for malware, and updating the operating system and drivers. Additionally, consider upgrading the RAM or replacing the hard drive with a solid-state drive (SSD) for improved performance. If these steps do not improve the speed, it may be worth consulting a professional for further assistance. **

It's best to check with Lenovo's warranty terms and conditions or consult with their customer support to confirm whether replacing the hard drive will void the warranty. **
