Resposta para "Blackberry z10 appears not to be charging and will not come on?"I had this problem as well. It sounds like the battery is completely discharged. The micro usb port may not be making a connection. When the phone is charging a small yellow lightning bolt appears at the top left hand (on the screen) next to the battery condition symbol. You can get a new battery from Amazon, but that may not be the problem. I purchased a charging dock from DX.com (http://www.dx.com/p/2-in-1-battery-charger-charging-docking-station-for-blackberry-q10-black-223137#.V_4y4dyrf2k) for $10 incl shipping and then a spare battery. My micro usb port just wont charge any more, but the dock will charge batteries. The battery is easy to remove by prying the cover from a small notch at the bottom edge. The battery can be pulled out and charged. Batteries are only about $10.
