I also have a Strix Halo zbook G1A and I am quite disappointed in the idle power consumption as it hovers around 8W.

Adding to that, it is very picky about which power brick it accepts (not every 140W PD compliant works) and the one that comes with the laptop is bulky and heavy. I am used to plugging my laptop into whatever USB-C PD adapter is around, down to 20W phone chargers. Having the zbook refuse to charge on them is a big downgrade for me.

It's Dell, they are probably not actually using PD3.1 to achieve the 140w mark, instead they are prolly using PD3.0 extension and shove 20v7a into the laptop. I can't find any info, but you can check on the charger.

If it lists 28V then it's 3.1, else 3.0. If it's 3.1 you can get a Baseus PowerMega 140W PD3.1, seems like a reeeeally solid charger from my limited use.

It is HP, and the output of the provided adapter does 28V 5A, so in spec.

With some of the other 28V 5A adapters I have, it charges until triggering a compute heavy task and then stops. I have seen reports online of people seeing this behavior with the official adapter. My theory is that the laptop itself does not accept any ripple at all.

Ah my bad. Are you sure your cable can do 140w? That was the source of most of my pains trying to push 100w to my work laptop. Baseus and Anker have some good PD3.1 chipped cables that worked for me. What kind of charger are you using?

I am also on search of good portable brick to replace 140w. I found 100w Anker Prime was working well. And surprisingly there is almost identical 3 port Baseus 100w GaN but half the price. For some reason it is hard to come by (they have few other 100w bricks that are not so portable) i think it might be discontinued.
