Hmm; I've not tweaked that one -- I'm using:

options i915 semaphores=1 i915_enable_rc6=7 i915_enable_fbc=1 lvds_downclock=1

And things are fine graphics wise -- I'm going to give it a proper run in tomorrow @work and we'll see how it goes.. Played a 1080p film on it earlier with mpv and it ate about 20% -- had brightness at about medium.. Not sure if that's good or not..

4W seems a bit optimistic though doesn't it? I've tweaked things quite a bit, but maybe I'm missing some extra magic or I just don't know the machine enough to know what the baseline is...

I've got skype, spotify, maybe 20 firefox tabs, dozen terms or so, dwm, wpa_sup wifi, and some other stuff, and i'm currently at:

System baseline power is estimated at 11.8 W

Freq Throttling (this isn't controlable, seemingly, and handled by the intel_pstate driver) currently has me on: current CPU frequency: 526 MHz (asserted by call to hardware)

Don't really have a baseline yet -- I can drop a reply in here tomorrow if you're interested in how it holds up with some real use?

I have one and the answer is no.

I had no idea this was actually a thing before this morning :(

It seems to only happen when there is graphics stress -- using "semaphores=1 i915_enable_rc6=7 i915_enable_fbc=1" seems to help, and once I started playing videos with --hwdec it was quieter also..

As it only happens during video, and I usually have headphones or the speakers going at those times I'm not too bugged by it yet..

Doing a kernel compile or something noisy in a term doesn't seem to trigger it..

I'm not sure I really believe any os can actually drive NVMe, 3somethingx1080 touchscreen, 16GB of ram and a quad core 17 for 22 hours with this hw setup while doing anything remotely resembling normal use.....

This machine will be my work luggable, I'm pretty sure it'll hold up all day.

First real run is tomorrow (dev+infra stuphz), I'll drop back in and let you know how it lasted if you're interested?

edit: anyone/any-os

I'm using Arch Linux on one of these and absolutely everything (including the touchscreen, suspend/resume, etc) has worked out of the box; the only things I had to mess around with were UEFI (since I've been on macs for years and just came back) -- "libvaapi" so that mpv uses hardware accel, and to install the intel-microcode initrd, and hacking dwm's config.h for ages...

There is a patch to make the nvme drive last a bit longer mentioned on the arch wiki (I've not tried it yet, tbh):

I have one of these laptops (since Friday):

* ) Batt -- Still tweaking things, I dropped the ubuntu install pretty quick for arch, but I recon 9-10 hours is where I'm sitting atm.

) Headphones sound fine here...

) Wifi Perf? I get ~250mbit on fast.com from my house

The bigger issue is the graphics card whine under high load....
