“Do the HDMI 2.1 ports support HDMI Cable Power by using the HDMI 2.1a cable? In other words, can the HDMI 2.1 ports provide power like the Thunderbolt 4 ports if using the HDMI 2.1a cables?”

• Hello, the HDMI port does not support power to this laptop. You must use the included 200-watt adapter with barral plug or use a high wattage (65w and above) USB-C brick and cable. USB-C charging only works when the laptop is completely off.

• Yes, it's one of the criteria for an HDMI port to be version 2.1 compatible.
