The Low Power Mode setting shuts down the network adapter.
In the Bios Settings expand Power Management, and then disable Low Power Mode.

i tried that also, its not working.
Michael-BestCommented:
Low Power Mode is enabled by default.
To disable Low Power Mode, uncheck its box.
That should allow the "wake on lan" setting to take effect.

Is Windows updated?  Plus did you try to configure the magic packet to wake the computer  in device management.

windows key +r

Type: devmgmt.msc

Locate the Network adapter and right-click------>Properties and Click on the Power Management Tab.

Also check the Advance Tab for something stating Wake on Magic Packet
