When you say "reboot", does it act as if you had pressed the Home button? I've had that happen when holding the ipad with my thumb too close to the Home button.
If you mean the iPad acts as if it had just been woke up and wants you to Slide to Unlock, it sounds like there is a loose connection inside the iPad.
One thing you can try is to reset (reboot) the iPad. Hold both the Home and Sleep buttons for several seconds until the Apple logo appears. Ignore the "Slide to power off" arrow. The iPad will restart after a couple of minutes. Resetting this way will not hurt anything, and sometimes clears up mysterious problems.
If that doesn't help and you can show it to an Apple Store Genius, you may get a new iPad on the spot.
Here's my issue and it's similar: every 4-5 days or so, I'll be using my iPad and all of a sudden it reboots. In other words, screen goes black, white Apple appears and I'm at the apps menu again. No rhyme or reason to it and not tied to a specific app as far as I can tell. Is this a software issue or a hardware issue?
Yes! You might try the reset/reboot I mentioned above, but it could still reboot in another 4 -5 days.
I suppose you might have a rogue App that is running in the background. If you double-click your iPad's Home button, a row of recent Apps will line up along the bottom of the screen. Press and hold on one until they start to wiggle. A red minus sign will appear on each icon. Touch the minus sign to remove each from the list. That will also stop Apps that might be running in the background.
Based on the random nature of your problem, I suspect it is a loose connection inside the iPad. If so, tapping lightly on the iPad in various places should eventually cause it to reboot. If you can remember what you were doing and where you happened to be touching or tapping the iPad when it happened, it might help in troubleshooting.
It is also possible a component is temperature sensitive and causing the reboot when the iPad gets hot. Whatever the problem, it is not normal. If yours is an iPad 2, you should contact Apple before the warranty expires.
I do not know what the solution was, but the problem is not normal. If your iPad is still in warranty, you should show it to an Apple Store Genius. If the Genius can not fix it, you may get a replacement on the spot.
If out of warranty or there is no Apple Store near you, look for an Apple Authorized Repair Center. There may be one in your city. <Apple Repair Center> If out of warranty, a repair should be less expensive than Apple's exchange price.
I have the same problem and have had 2 (yes 2 ) replacements from Apple. The first one I downloaded 6.0.1 as required and bang....problem emerged again (pure vanilla IPAD no apps installed.) Back to Apple and once again they supplied a replacement. Used for 2 days with NO problems and having NOT installed 6.0.1 - guess what ...as soon as I applied the update here we go again !!! I will return to Apple once again to ask them to return it to 6.0.0 (not hopeful they will oblige) as this will be the only way I can convince them there is a problem...this is driving me nuts (i have been in IT for 25 years so I am not a newbie..) I have done all the resets known to modern man to no avail..
I am had a similar exact problem. My iPad 2 kept rebooting itself when I upgraded to IOS 6. The frequency of reboots increased when I installed the IOS 6 patch recently released by apple and the device became unusable. I ran to apple genius and the guy there said its a software problem (some security file). I was then asked to pay 200£ to get a like for like replacement becasue I am out of warranty. I rasied a complaint with Apple and Apple technical gurus and mangers called me to discuss the issue and I still not convinced that its a hardware issue. Putting back IOS 5 on the device will be a good test to see if we can simulate the problem, but apple says they cant do that. Please let me know about your expereince with this problem, I will add you case to my complaint and may be we can back each others case.
I have iPad 3g+wifi 64 gb with and it's 2 years more old.
once a while it's fine, until suddenly there are "no simcard" issues after sleeping at night.
After that problem, i never had any signal using "any" simcard. also, after inserting simcard into my iPad, suddenly my ipad had this restart problem. so.. i were trying :
1. reset network --- > still have a problem.
2. restore on itunes ---> still have this problem though
3. reset all settings ---> this one is good though, if you were reset all settings and you can see progress bar completing until the bar is full then next time it's finish reset, i can guarentee that my ipad will goes to "normal" even until now i only can use wifi only. if you already tried reset all settings didnt change reboot suddenly behaviour, then you must try reset all settings all the time until you let it ipad without activating it for at least 10 minutes.
for apple inc.
i hope you can fix this problem either it's hardware or software problem. mine is out of warranty but you need to handle this carefully, and don't let apple people say "I NEVER SEE THIS PROBLEM BEFORE" because you already had this communities and you sell product expensive as we bought it expensive as you sold. i have no intentions using genius bar if the solutions is only "REPLACE" but i have to pay another 4xx USD for a change because my iPad is no warranty. fix the problem or your customers go away. apple also has many issues right now including suddenly apps closing. hope apple inc willing to do their bests just like before. again.
Please, guys, are you seriously acting like this is a new problem? My iPad 1 has this problem, and has always had it. quite often, for no apparent reason, and no, I´m not touching any buttons, when on Safari, it just goes on to sleep = dark screen. Has to be started just normally, then slide to open, and it comes back to the page on Safari.
It is rather worrying to hear that the problem persist on the new Air, since I am just about to buy one, and I really did hope that they had fixed this problem?
but, I don´t think so.
It happens out of the blue, quite often just after I have opened a new page in Safari.
Anyway, just bought a new Air, loving it, except it did what my old "1" never did, within two days of use it just froze on a page whilst trying to enter some info. Had to reboot it to get it back to life. Other times it has looked like it froze, but it was just taking VERY long time to think??? Worrying???
