Won't Turn On / No Power
When your device refuses to power on, the cause is almost always one of a few things: a power supply issue, a tripped safety switch, a blown fuse, or a dead battery. Before assuming the worst, work through the basics — you'd be surprised how often the fix is a tripped GFCI outlet or a safety interlock that wasn't engaged.
