Screen dimmed Safari & no movement

The first way simpler to resolve the problems of ?unexplained? or ?unusual? with the iPad are:-.

Force the offender app to close. If you have iOS 4.2 or 4.3 double-press the ?Home? button to appear the multitasking bar at the bottom of the screen. Press * and hold * any icon until what they begin to ?jiggle?. Then click on the upper left corner of the application you want to close. It will be ?disappear? from the list. Don?t panic - you?ve delete, just its closure. Now take advantage of the home screen and multitasking bar will disappear. Reopen the iPad?s app and see if the problem is solved itself. Otherwise, it?s possible solution number two!
Restart the iPad. Press * and hold * power button. After a few seconds a slider control will appear asking you to confirm that you really want to turn off the iPad (this is the you?ll to do). Drag the control to accept. White ?bezel? rotation will appear on the iPad as the powers down iPad screen (it takes a few seconds, just as it would if you were close your PC). When the iPad screen has disappeared completely white, press * and hold * power button for a few seconds until the white Apple logo appears and the iPad starts to power. This takes a few seconds, then be patient. The power to the automatic screen orientation feature is turned off, so don?t panic. Seconds until the tension is over, the iPad plays a little ?jingle?, then you?re back to the home screen. Restart the iPad?s application and see if the problem persists. Apple (and the members of the Forum) recommend that you put your iPad at least once a week, just as you can regularly extinguish completely from your PC. The normal procedure of briefly simply pressing the button of the iPad feed updates ?sleep?. Most Forum members have found that one of the two methods mentioned here i?ve cure a whole bunch of problems that unexplained and constitute a first easy step to solve something most is happening on the iPad.
