Motorola Droid 4 xt894 won't turn on Yesterday I charge my phone using USB till this morning, but now it won't show start, i've tried:


pressing power button >3s
pressing power and volume down button >10s


but it doesn't work.

when plugged to USB, it still show green light, is there any other button to force restart?

I'm using working Cyanogenmod.
Apparently it was out of power, plugging into USB and wait for a few minutes then press power + vol down for 10 secs to turn it on
