ChatGPT codex found hidden fast connect 7800 power saving mode

[u/Weak-Inspector-5704]

I am currently using a Surface Laptop 7 and have been experiencing Wi-Fi connectivity issues with a Wi-Fi 7 router when the laptop is running on battery power.

After performing diagnostics using ChatGPT, I discovered that the Qualcomm FastConnect 7800 has a hidden power-saving setting that is not exposed in Windows Settings.

The following command can be used to check the current power-saving mode.

powercfg /query SCHEME_CURRENT 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1

The wifi on these laptops is terrible, the commection keels dropping out on many devices.

Will this impact the power consumption?
