Dell Inspiron 15 7000 ASF2 Force off

Hello,

Since two days my laptop (Dell Inspiron 15 7000) is shutting down instead of going to sleep when I press the power button. 

In the event log from the bios, the event is labelled as ASF2 Force off.

I can't pinpoint the change maybe I did that brought this problem.

Any help will greatly be appreciated.

Thank you
