Why won't my Note 4 power on?

[AC Question]

NOte 4 will not power on

I put my phone on the charger last night and I had an Android robot on the screen and it said do not power off. There were some little words up in the left corner that said boost and a few other things.

Re: NOte 4 will not power on

Welcome to Android Central! If it's Download Mode, then as long as the phone isn't connected to the computer, it's ok to power down and then power up again. Download Mode is usually started by pressing Home, Power, and Vol Down at the same time--do you recall doing that?
