Windows 10: My gaming laptop is suddenly running very slow

I've been struggling with this issue for a while now, and I can't take it anymore. My laptop is unbearably slow! I was playing some games as usual without plugging the laptop into the wall, and when the battery got low, it naturally slowed down and started lagging. I thought it was just because of the low battery, but after plugging it in, the performance didn't improve. I did a fresh install of Windows, hoping that would fix the problem, but my laptop's performance hasn't improved at all. If anyone can help me resolve this issue, I would greatly appreciate it. Here are the specs of my lapto

Lenovo laptop suddenly slow

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?

Why has my Laptop suddenly started running slow




















OK have done the above. Hardware seems fine, no?

PS I have set Performance Manager running. It said it is "Collecting data for 60 seconds..." however my computer is running SO slowly that after what is now 15 minutes (and counting) it has not spat out any results (!).
