I have a Lenovo E580 laptop (bought in Jan 2019) that suddenly became slow. It’s affecting build times in Visual Studio and loading times for a local website on IIS. I tried reinstalling Windows 10 Pro, but it didn’t improve the performance.

Laptop specs:

  • Windows 10 Pro 64-bit
  • CPU: i7-8550U 2.00GHz
  • 16 GB RAM
  • 512 SSD

The slowness is noticeable in these software:

  • Visual Studio Community 2019 Version 16.3.9
  • IIS on Windows 10

I compared the laptop to an older one with similar specs (i7-4700MQ 2.40GHz, 16GB RAM, 256 SSD) and similar software. The new laptop takes 78 secs to load a local website, while the old one takes only 30 secs. Previously, the new laptop loaded the website in 30 secs as well.

The issue is affecting the entire laptop, not just Visual Studio and IIS. Despite formatting and reinstalling Windows, the problem persists. I suspect a hardware issue, but there are no error messages and everything appears fine.

Do you have suggestions for troubleshooting this issue or should I contact Lenovo support (since the laptop is still under warranty)?
