Inspiron 14 5000 heats after shut down

Hi,

My Dell Inspiron 14 - 5000 series heats up after shut down and then it doesn't turn on by pressing the power bottom. In order to turn it on again, I have to press the power  bottom for 12 seconds.

 This is an intermitent problem, some times it happens others it shuts off normally and then turns on normally. 

The configuration is WIN10 Pro 64bits, 8GB RAM, SDD 500 GB, BIOS v10. 

Please some help.

Thanks,

Pablo.
