Why is my ipad2 not charging, it just shows the plug and a arrow pointing to the iTunes emblem?

Your iPad is in restore mode. If you boot the device while holding the home button, it will boot into restore mode for a clean firmware install or a restore from backup.

you can either hard reset the device by holding the sleep/wake and home buttons down simultaneously for 8 seconds, tether it to a computer and complete the restore, or just leave it alone for about 20 minutes and the restore timeout wll kick it back into normal operation as long as there is a good firmware install present

if it is an Android, you can purposely max out the attempts and log in using your google account info on most android devices. If it is an Apple iPad, you would need to connect to pc/mac and go into iTunes to reset the device. This can be done by plugging iPad in then holding the home and lock/power buttons until you see the "Connect To iTunes logo. This screen can be identified by the charging cable under an arrow pointing to the iTunes logo. the pc/mac will detect device in recovery mode and alert you that you need to restore the device before you can use it.

Seems that your iPad has been reset to factory. You will have to plug it into your computer and launch iTunes. From there you should be able to restore from your previous sync. It helps if you use the computer you originally set up the iPad with.

USB hubs typically don't generate the 10 watts necessary to charge an iPad when it's connected to your computer. This basically means you can't use your laptop to recharge your iPad.

Apple recommends finding an AC outlet and using 10-watt power adapter that came with your iPad.
