Won't go into sleep mode.

[Android Central Question]

I have a 2014 galaxy note 10.1. We replaced the battery because the old one would note hold a charge. Now, when I am finished with whatever I am doing it goes to sleep, or should I say deep sleep because now I have to completely turn it back on. It no longer just goes to sleep so I can use the home button to wake it up. Not sure how to fix.
Thanks for any help
