A1-840 goes to sleep then I can't wake it up

When I set the tablet down, it goes to sleep and I can't wake it up. The 5-finger touch won't work. Using the on/off button does nothing. Most times I can wake it up by holding down the on/off and the volume up at the same time for 15 second and the pressing and holding the on/off. 

 

Seems to be a lot of effort to wake it up.

 

New tablet.

Android 4.4.4

 

Thanks for any help.
