Switch on notebook

You can wake on LAN, or you can wake on USB or keyboard, etc

There should be settings in your BIOS to do these.

Now I can't switch on the notebook to do the setting in bios because the power switch got problem.

Oh...you have a physical problem with the power switch. I know that you could take it apart, if you feel comfortable, and manually press the connector to power it up, but I'd try to get it repaired by someone who does this professionally.
