XPS 15 9550 - Waking Up Laptop From Sleep

In order to wake up my laptop from sleeping I have to hit the power button. The Dell Logo appears and then I'm prompted to sign in. Normally with other laptops I just hit any key and it returns me to my desktop.

Is there something wrong with my laptop or is it normal for these laptops to have to hit the power button to wake it up from sleep?

Thanks.
