I find this immensely frustrating.

My work laptop (HP ZBook Studio 16 G11 - the current model) will will only charge from the USB C ports on the left side, not the right side. Unfortunately, that is low down my list of charging complaints for that laptop. It will not charge from USB C unless it is given a power supply that is at least 100W, even if it then only draws a fraction of that.

There is an exception, where it will charge from a lower wattage power supply (like 60W) when in standby or turned off. Often, it is happily charging away, and as soon as you wake it up, it stops taking any power. As soon as I need more, it takes less. And it is definitely not the case that it is draining faster than it is charging. It just stops charging.

Presumably, the justification for all this mess is that it is only supposed to be charged from the barrel plug 180W power supply, but with a weight starting at 1.73 kg, I would rather not lug a 1/2 kg power supply too.

Perhaps in all their efforts to make it slim and lightweight, they wanted to avoid extra power circuitry. After all, in their efforts to slim it down, they also cut an HDMI/DisplayPort, a camera cover - everything in fact except 3 USB C (not all thunderbolt), a USB A and a 3.5mm audio port. Our office meeting rooms are nicely wired with HDMI and USB-C chargers, but people are still forever trying to locate an HDMI adapter, or going back to their desks to get their power supply.
