Arya RoyThe iPad is a touchscreen tablet PC made by Apple which is used by many for a variety of purposes, such as entertainment, learning, non-SIM communication, work, etc. However, like any other technological device, it is common for the iPad to run into some technical issues. That being said, there is a solution to this: hard resetting it.
If your iPad happens to be frozen and is preventing you from unlocking it through the use of your passcode, or if it simply fails to recognise your taps, or if the slider is not working, a hard reset/hard reboot of your iPad will often do the trick. This will force the iPad to turn off and on and will flush its memory clean. However, there is no need to worry, because a hard reset does not delete your data.
Click on the Home button and the On/Off button at the same time. Keep holding the buttons down until after the screen turns black and the iPad restarts itself. Release the buttons only when the Apple logo will be made visible on the screen.
You will now be able to access the iPad, provided that you know what the password is. If you still think that you need to erase the data and restore it to factory settings, you can do that either with iTunes or from the iPad settings.
How to reset the iPad with iTunes
Resetting an iPad is time-sensitive, and your computer will be required to download and install software on the iPad. If the process exceeds the time limit of 15 minutes, it will automatically abort the process and you will have to start all the procedures over again.
Sign into iTunes on your computer. Note that will need to know your Apple ID and password to reset the iPad.
