My Dell 14z just one month old always crashes when I close the lid if 'close the lid' does Sleep in Power Mgt settings.

It always did this.

(have to hold down Power button to start, then it says 'Windows has recovered from an unexpected shutdown').

Fan is still going after shut the lid, seems not to be acutally shut down. 

When I changed the setting to Hibernate on close lid it does not crash. 

I can Suspend (is that the same as sleep?) using the Shutdown button on the Start menu.
