Agreed. Every time I tried windows it was the same set of frustrating behaviors. Linux helps but needs some tinkering. My first step on a new laptop would be to wipe clean and install Linux.

I have a T440 which runs quite hot, where did you look for sources of power usage (beyond powertop) ?

I run Ubuntu on a X1 Extreme Gen 2 for a while now, no problems whatsoever. The discrete nVidia GPU is as power hungry, and running as hot during gaming, as it did under Windows (so nether a big surprise nor a real problem, anyone remember how harsh Battletech was on GPUs initially?). Battery live, depending on use (and excluding gaming) is around 4 hours (didn't have less then 3+).

The heat issue is mitigated somewhat by putting the machine on some kind of stand to have air pass underneath it. That being said, even under Windows the machine went to sleep just fine, also woke up again. If anything, that works better now under Linux.

There is a difference between T440 and T440s. T440s is already power optimized and runs integrated GPU vs T440 which is more normal laptop with discrete graphics.

I used mostly powertop but this is less reliable source of information when you are running discrete graphics card.

My T440 does not have a discrete GPU.

It's basically a T440s without the touchpad. But it's got an i7, of that matters.

As an i7, is it quad core? I had a T440p with i7-4700MQ and it had terrible power consumption compared to prior and later Thinkpads I have experienced.

What I saw in powertop was that it never got into the better "package" power states. The cores could all be spending 90%+ of the time in C7 but the package as a whole was in C2 or worse. I never found a way to fix this.

Mine had the NVIDIA GPU as well as Intel iGPU, and I primarily used it with the iGPU. The NVIDIA was of the sort that was not connected to a physical output, so it supposedly could be powered down when not being used. I had no way to truly verify this, of course.

Nah, just a dual-core i7 @ 2.1 GHz. I got that laptop 2nd hand, so that was it.

I don't get into the bios very often so I might be wrong, but I don't recall seeing any indication of an nvidia gpu in mine. I'll look better!

On my T440p, the Intel and NVIDIA GPUs would show up via 'lspci'. I don't recall whether there were any BIOS options other than internal vs external display during POST/boot.

I hate it too. I’m not just saying that, I ran Linux as my only desktop for 3 years and exclusively AOSP phones for over 4.

Ultimately, however, some of us have stuff to do and can’t spend our entire time tinkering to maintain basic functionality. There are only so many hours in a day.

Thanks. I wasn't aware. English isn't my native language.

nay: unless, of course, the force of course is the famous grandparent

2c: Had an XPS15 die the other day, won't buy another. Also sworn off Apple hardware. Using Lenovo laptop. All good.

Unfortunately these issues exist in Linux as well. There's no S3 in the bios.
