In comparison, my Thinkpad P1 Gen 3 I bought a month ago keeps the fans running while it is sleeping. The machine is warm to the touch all the time. From what I've read, Lenovo blames it on Microsoft's modern sleep requirements.

This morning I configured it to hibernate after 30 minutes, so I hope that fixes the problem.

I'm staying away from Lenovo ever since buying an IdeaPad laptop in 2018 with a fan so obnoxious that I literally could not get any work done. Lenovo needs to get their shit together.

Go into the bios and change the sleep setting so that it uses S3 sleep (traditional) rather than S5 sleep (modern). Now your computer will actually turn off and stay off, and it's only using a very small amount of power to keep the memory on.

It's comical how bad Windows S5 sleep is. Laptops waking up and running while they're in a bag should be the kind of bug that prevents an operating system from being released! But here we are in 2021, years after Windows 10 was released, and this is still common place.

My next laptop will absolutely not be a PC.

S3 sleep has been removed from the options for devices. Dell actually pushed out a bios update that removed the option. I can see what MS wanted to do with modern sleep, the macbook is able do to things like beep when you ping it via find my while it is sleeping which is impossible in S3 sleep. But the current execution of it is horrible.

My Lenovo X1 Carbon still has the S3 sleep option in the bios thankfully!

But yeah seriously, Modern sleep is one of the primary reasons I'll never get another Windows laptop after this.
