Steps to add/remove 'Link State Power Management' from Power Options in Windows 10
The link state of a PCIe device is converted from L0 (on) to L1 (off) when the link is not transmitting data. Hardware is automatically converted back to L0 when data is available for transmission over the link.
There are basically 2 levels of power management in the PCI Express options. The difference between these 2 options is the ability to save power compared to latency (time to recover from Sleep state).
Users can specify the following ASPM policies:
- Off = Disables ASPM for all links.
- Moderate power savings = The system tries to use the L0 state when the link is down.
- Maximum power savings = The system tries to use the L1 state when the link is down.
This tutorial will show you how to add or remove Link State Power Management settings in PCI Express under Power Options for all users in Windows 7, Windows 8 and Windows 10.
Note: You must be logged in with admin rights to add or remove this setting in Power Options.
