Hi
I’ve used powercfg/ energy and one of the errors is active save power management is disabled due to hardware incompatibility
Drivers are all installed what I’ve todo ?
 
active save power management is disabled due to hardware incompatibility
Active-State Power Management (ASPM) saves power in the Peripheral Component Interconnect Express (PCI Express or PCIe) subsystem by setting a lower power state for PCIe links when the devices to which they connect are not in use.

Most common PCI-E device is dedicated GPU. Whereby it could be, that your dedicated GPU doesn't support the low-power state, offered by ASPM.
There are other PCI-E devices, like sound cards, old wi-fi cards, capture cards etc.

Also, it sounds like you have a laptop. Does your laptop even have dedicated GPU in it?
 
As i said above, ASPM controls PCI-E devices lower power state. GPU is one of such PCI-E device. M.2 NVMe SSD is another one. So, what it actually is - unknown. Could be one of them, some of them or all of them.

Also, it isn't an "error" in it's true sense. Just because hardware doesn't support lower power state, doesn't mean it is an "error" what needs to be fixed.
E.g open up Event Viewer and you'll see plenty of "errors". Most of them (if not all of them), you can not "fix".
