Wake-on-LAN functionality does not work on Windows Vista-based computers that use Broadcom network adapters and that have the _OSC method enabled
This article has been archived. It is offered "as is" and will no longer be updated.
Consider the following scenario:
- You have a computer that uses a Broadcom network adapter.
- You enable the Wake-on-LAN (WOL) functionality on this computer.
- The computer has the Operating System Capabilities (_OSC) method enabled to configure power management.
In this scenario, the computer does not resume from hibernation (S4) or from standby (S3).
This problem occurs because power management in Windows is performed by the PCI Bus driver (PCI.sys) instead of by ACPI.sys.
If you enable the _OSC method in the BIOS, the method does not wake the computer up from S4 or S3 mode when the network adapter receives a Wake-on-LAN (WOL) packet.
To work around this problem, disable the _OSC method if it is enabled in the BIOS.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
