i7352 won't wake up from external keyboard or mouse

I have a brand new Inspiron 7352 pre-installed with Windows 10 with a docking station and external keyboard, mouse, and monitor. Due to limited space, I would like to keep the laptop closed all the time and tucked away under a monitor stand. When the laptop goes to sleep, the only way to wake it is to open the lid and push the power button. I would really like to be able to wake it up using my external keyboard or mouse. I spent 90+ minutes online last night with Geek Squad help. Here is the conclusion they reached: when you open Device Manager and look at either the external keyboard or mouse, there are NO power options (unlike earlier versions of Windows?). This seems to be a limitation of this laptop + this version of Windows. Geek Squad suggested that I contact Dell Support and see if any fixes are available.
