Samsung j7 2016

[Android Central Question]

My Samsung J7 2016 automatically turned off last night. I tried the possible option like : 1. Turning On by pressing Power Button.
2. Pressing and Holding power and volume down key
3. Removing battery and the powering on/ Charging.

but none of these methods worked.
Then I plugged my phone into laptop and checked for any Hardware in DEVICE MANAGER. When i power up my phone, it shows hardware sign (Exynos) for a second and then blank. I tried this 4 5 times but nothing happens. Please help me what to do.

Welcome to Android Central! Keep it plugged into a wall outlet for at least 6 hours, undisturbed. Then press and hold Power for about 20 seconds. Does it power on now? If not, then try a new or different battery.
