Power on with PC

If it does not turn on by itself, while you connect it to the PC, press and hold the volume down button until you see a boot menu that allows you to turn it on. In other models it can work by holding the volume down and home button.

Start from recovery or fastboot
Try to enter recovery or fastboot mode (or download mode on Samsung devices). These are special boot modes of the cell phone, from where you can select the option to restart the phone.

adb reboot, and in the second case
fastboot reboot. This is done from the ADB and Fastboot program.
