BIOS VERSION

3.05

DIY Edition information

Memory: FW 2x16gb
Storage: Samsung 970 EVO Plus

Port/Peripheral information

Affects all charge capable ports with usb-c expansions (if I remember correctly, i tested with direct connection as well)

• HP Thunderbolt Dock 120W G4
• ISY IAC-5140-WT (PD 140W single port max power adapter)

Standalone Operation

Are you running your mainboard as a standalone device. Is standalone mode enabled in the BIOS?

• Yes
• No

Describe the bug

In reality this could be 2 separate issues that interact with each other.

Bug A: HP dock does not provide full 100W PD supply, instead it is set to 20V, 3.25A (as reported by linux) and never switches up to 5A.

Bug B: 140W charger makes linux confused. Sensors report 0V 5A while the battery charging seems to work at full power. Running games in this state results in worse performance than 100W chargers, with dgpu clocks constantly jump between power states (mid to high?) and makes FPS jump as well.

Where it becomes weird is with the charger from bug B. Bug A I had for a long time and at some point chucked it off to HP sucking ass (it had other bugs not related). When I would connect a 2nd cable to 140w charger with nothing on the other end, the bug B would stop and instead turns into bug A.

I do posses other 100w bricks that behave correctly and do not experience this. As I remember testing, bug A happens on my thinkpad e4 running fedora with the HP dock as well. I have not tested bug B with it. The cables do not seem to matter (i have not tested many, but I did some, most cables are USB4 spec)

Steps To Reproduce

1. Get unlucky with your charger.
2. Connect it to FW.
3. Suffer. (look at lm_sensors)

Expected behavior

Get expected PD power (20V 5A or 28V 5A). Have no silly stuff happen with dGPU performance.

--------------------------------------------
and here i am trying to stress the system, but no matter what i do i cannot make it start using the battery as well -> shitty performance

Additional context

I have decided to finally stop sitting on my, at this point hardboiled, eggs and document my problems here and not just share my ramblings with @DHowett (thank you for listening <3). I do not think the dGPU could be a cause, i think it also gets confused by 0V reported. I do get the classical usci_acpi errors. I'll try to test further, but I could be AWOL. Maybe Howett can fill in some blind spots.
