I have a new Lenovo E580 laptop (bought January 2019) which suddenly started to run very slow. I have especially noticed it with build times in Visual Studio and loading times for a local website in IIS.
I have tried to reinstall Windows 10 Pro by formatting the entire computer but it’s still slow.
Laptop spec:
- Windows 10 Pro 64-bit
- CPU: i7-8550U 2.00GHz
- 16 GB RAM
- 512 SSD
Software where I really notice the slowness:
- Visual Studio Community 2019 Version 16.3.9
- IIS to Windows 10
I have tried to setup an older laptop with the same software installed as the new laptop, to compare the loading times. The old laptop has a very similar spec. (i7-4700MQ 2.40GHz, 16GB RAM, 256 SSD). The load time for a local website on the new laptop is 78 seconds where on the old is 30 seconds. On the new laptop it used to be around 30 seconds as well.
It’s not just Visual Studio and IIS that is slow it’s the entire laptop. I thought it would be fixed by reinstalling Windows but there were no improvements. I suspect it’s a hardware issue, but I don’t get any errors, and everything looks fine.
Does anyone have suggestions to what I can try to pinpoint this issue or is it better to contact Lenovo support, as the new laptop is still under warranty?
Answer
I had been experiencing the same issues myself lately. But I updated BIOS & firmware via Lenovo Vantage today and it sorted everything out. The CPU consumes as much power as it needs and VS compilation process is pretty fast again.
