    I think that is what it is called ~ but is there a way to turn that off? What is the point of having it go to sleep? To save on the battery?


    I just got a really cool screen saver and I never get to see it because the iPad goes to sleep!:(

    Yes, it saves on battery. You can go to settings and tell it to never turn off, but I can't imagine why anyone would want to do that.

    I agree I usually plug my iPad into power at night. In sleep mode.

    Silly question:

    Is the iPad's screen vulnerable to image burn-in (or "transient image persistence")? I always used the sleep mode for fear of messing up the display, but I really don't know if that's a technically valid concern.

    So you cannot really disable "Sleep" mode and have the sleep/wake button be a true Off? Just make it not sleep and have the screen always on? iPad never sleeps? LOL We always wanted a device/computer that had instant on with no booting. Now we have one [mostly]

    Is SJ watching us?:D

    You can sort of...you can tell the screen to never time out. Also, if you hold the sleep button in it will ask you to slide to turn off...but if you turn it off and plug it in, it will automatically turn back on.

    Hi Matt;
    I did discover the hold it in just recently and I guess that is really not too bad. I see where Windows 8 is looking at some sort of iPad-like instant on. I was never too happy with the hibernate or sleep function in Windows. The Microsoft jockeys never were allowed to keep everything in memory. HD is not a very fast substitute. Of course, they were going for volume user.

    not a silly question... I always thought that LCD screens were not suspectible to any kind of image burn-in... but I have proof right on my desktop, an LCD screen that I have had for 5+ years, with app windows ALWAYS in the same place, sure enough, there is a clear residual burn in at the edges of each of those app windows when I close down those windows. I can only surmise that after so many years of the transistors driving those particular pixels, that they are wearing out (heat, electromigration, etc)...

    BUT that is after many years with windows/icons in exactly the same place. LCD screens aren't nearby as bad as CRTs for burnin where you are bombarding phosphors with electrons. So I wouldn't worry too much, especially if you don't have fixed patterns displaying (like edges of a photo always using the same pixels).

    Monkey, have you tried one of those apps that unsticks pixels by flashing all the colors?

    It is actually called Auto-Lock. To get to it, go to Settings | General | Auto-Lock.

    [​IMG]

    This is the amount of time that the screen will shut off after no activity. Unfortunately, the longest amount of time you can set it to (other than Never) is 15 minutes.

    Why leave the television on if you are not watching anything?

    Why leave your car engine running if you are not going anywhere?

    Worst of all, why leave a cooker switched on if you are not doing any cooking?

    I don't see any reasons why we can't put our iPads to sleep if we're not using it for a while, while we are busy doing a lot of other things. Or switch it off if we are not going to use it for a very long time.

    Yes, it may be to "save battery", leaving the iPad totally on, with Wi-Fi and 3G and location service all switched on, and the screen brightens set to the maximum, would drain the power faster, while doing it the other way round, sleep mode, settings turned off, screen brightnes set lower, etc., would give us some more extra mintues of power.

    But surely it helps a little bit to go green just for a bit, like putting your iPad in sleep mode (or ever turned off) to try to make the iPad last longer between recharging. Surely you would prefer to recharge your iPad every few days than if you leave it all-on and at maximum settings, draining your battery faster, so forcing you to recharge your iPad every day?

    I do use the sleep mode when I got other things to do, and do turn it off overnight. What's the point of leaving it on if I'm not using it?

    Major, I totally agree with you. However,
    Rather than switching it off I put mine to sleep overnight so that it comes on more quickly the next time I use it. However, if a compelling case can be made for actually switching it off (ie, conserving energy), then I'm all ears.

    Does the iPad use much energy in sleep mode? My battery meter doesn't seem to move overnight, but I will check this again.

    Thank you kindly.

    Point of note, when you wake up in the morning, the first thing you can always do is turn your iPad on, then while waiting for it to start up, you just do whatever you do whenever you wake up. Get coffee, go to the toilet, get dressed, let your cat in from overnight outing, something you really need to do, that won't take more than a minute. By the time you're done, your iPad will be ready.

    I would image it hardly use some power overnight while in sleep mode, maybe you'll only lose 1% of power overnight, if hardly any at all, but surely there are other matters to worry about? Why let the chips in the iPad be still running when not in use?

    If anyone wants to waste battery power, leaving everything on, that's their choice, if some like to leave theirs in sleep overnight, again their choice, I just don't see the point in having it on all the time when I'm not using it, or in sleep mode if I'm not ever going to use it for a few hours.
