My Apple iPad failed to power on. Luckily a reset fixed the issue. If you’re having the same problem with your iPad or iPhone, just follow these steps.
Note: If your device has gotten wet, don’t attempt to power it on. Instead, dry it for a day or two in silica gel or rice. Powering the device on while wet could permanently damage your device.
Force a Reset
Try to reset the device. To do this, quickly press and release “Volume Up” then “Volume Down“. From there, hold the Sleep“/”Wake” button until the Apple logo appears. On older models, Press and hold the “Power” and “Volume Down” buttons (“Power” and “Home” on older models) until you see the screen come on. Sometimes, it takes up to 20 seconds before you will see anything appear on the screen. So be patient and hopefully your device will eventually turn on.
Ensure Battery is Charged
If a reset doesn’t work, attach the iPad or iPhone to a wall power source. If the battery is completely drained, it may not power on right away. Keep it attached to the power source for at least an hour and see if anything changes. Make sure you use a wall outlet, as charging any other way may not provide enough power. Once you’re sure the device is charged, try the step 1 above again.
I know this may sound weird, but I have heard of people getting their phones to power back on after warming it up a bit. Use a hair dryer to warm the back of the device for about 15 seconds while it is plugged in seems to do the trick.
Try a Restore by connecting the device to your computer. If the device is detected in iTunes, select it in the left pane, then choose “Summary” > “Restore“. This will clear data from the device and restore it to factory default settings and hopefully make the iTouch work.
If the above steps didn’t help you out, you may have to seek help from Apple Support or the retailer at this point.
