If you read the rest of that thread, you'll find the issue was resolved and it was not an issue with the laptop:

> Issue was that I was running linux-zen, strangely. With linux-zen, the CPU wouldn’t get past C3 and idle power usage was 7-13W. With regular linux, the CPU reaches C8 and idle power usage is ~5W. Strange that linux-zen did that, but ok ig
The other main culprit is whether or not you can successfully enable PSR for the display. IIRC, the laptop cannot hit C8 or C10 sleep states without PSR enabled, even if you have the ASPM power saving mode enabled.
Speaking for myself, running Debian unstable, after lowering the display brightness, with the right settings my laptop easily hits 2.5-3W idle.
