> I absolutely hate it. It throttles constantly even after undervolting it. I had to do a bunch of black magic to get it to sleep properly (which is evidently happening to every Dell) and eventually gave up on that and just set it to hibernate any time the lids closed (it's 32gb so that adds about 30 seconds to the start up time). I've spent more time tweaking this thing, reading forums and reddit about how to make it perform DECENTLY than I did building my last hackintosh and I don't enjoy that experience ever. When you get past all these issues it's still Windows 10 which I just find to be the most annoying OS I've ever used.

Really? I love my XPS 7390 2-in-1, it's the best laptop I've used and owned by far and that includes Macbooks. Combined with a WD19TB dock (and a useful trick of flipping it around so it's an inverted L) it makes a great work from home setup. Its thermal profile is relatively aggressive by default but it should stay at 15W (and ~65 degree temps) indefinitely. Upping the power limit to 25W (like the Windows / Dell "Ultra Performance" mode does) and it appears it can maintain that too. I mean, Crysis can even run on the thing [1].

That said, I'd probably lose my mind if I had to run Windows on it. A suggestion for getting good old S3 sleep to work: enable the hack for reenabling S3 sleep in the Windows registry, then disable "Early Signs of Life / Dell Logo" in the BIOS [2]. I'm not sure if this will work on Windows, but it works flawlessly on Arch.

It seems like we're just waiting on bios updates for Ice Lake to have a proper thermal profile. I'm not sure. What happens is the laptops thermal profile is way under the Intel recommended profile. I believe it starts to throttle around 80* instead of the 100* or so Intel says Ice Lake should be able to run at.

It's been awhile since I played with this but I don't believe I was able to bump my voltage to 25w on Ice Lake. Maybe I'm wrong.

Maybe I'll do a fresh install and give it a try again. I've heard a few comments where peoples 7390 2in1s were running great but on /r/dell I've seen a lot more with complaints like mine.

I did get some improvement by dropping the thermal/power plan from High Performance down to Quiet. That seems to keep the thermals down so it triggers throttling less.

My problem is it throttles constantly and has other issues where if you move it (lift it up) while it's under load it will immediately throttle and I trigger it sitting on my lap a lot.

I bought it hoping I could run a bunch of VMs (thus the 32gb) and do light development work on it but I can barely even draw in Figma without having a rough experience so I completely gave up on developing on it.
