One morning my wife woke me up saying that her iPhone was dead, despite its having charged overnight. Figuring it was just turned off, or maybe had a dead battery, I plugged it in, held down the Sleep/Wake button and… nothing.
I stifled my urge to panic and began searching online for a solution, and I found one thanks to user Lawrence Finch at Apple’s Support Communities.
If your iPhone won’t turn on, try this:
- Toggle the Ring/Silent switch twice.
- Press and hold the Home and Sleep/Wake buttons at the same time until the Apple logo appears.
I confess that I have no idea how it works, but it did in this case.
If that doesn’t work, then try different cables and chargers, and failing that, there’s always the Genius Bar.
