iPad stuck in reboot cycle
February 18, 2012 2:13 AM Subscribe
My iPad 1 is stuck in a shutdown-reboot loop. I put it onto maximum brightness to use it outside, while attached to power. The app I was using, a graphically intensive game, drained it dry anyway. Now it is stuck in a situation where it charges up enough to start up, starts up, and being on max brightness, drains itself dry and shuts down again before I can get to the menu. The rocker switch is set to volume not brightness. I have tried various combinations of buttons. Any ideas?
How long is your battery lasting under normal usage? I've never had an issue like this. I also find it amazing that the power would drain while plugged in. You should be getting hours from a fully charged pad and should be able to do whatever you like while it's charging.
I would have it looked at and consider a battery replacement.
The iPad isn't supposed to start the boot process until it knows it has enough of a charge to complete the process. That yours is failing this means there is something else going on.
Just my thoughts.

Also, were you charging it off the beefy charger it came with, or something else?

Just to say the same thing has happened to me too, with the same result (eventually it charged enough to complete the boot process).

For future reference, I've heard some USB ports (laptop ones especially) don't quite put out the maximum possible amount of juice, so it might be worth plugging your device into a wall adapter or desktop PC if it's doing that sort of thing.

I've run into this when I accidently plugged in my iPhone charger instead of the bigger iPad charger. Just enough juice to light it up, but not really actually boot the thing fully.

Yeah, my four year old laptop won't charge my iPad. Has to be from the wall or a modern machine. It will trickle charge it if the iPad is off.
In the upper right of the iPad it should say "Not Charging" if it's not getting enough juice.

The standard rating for a USB port is 500mA and even that amount is only available after succesdul communication between the host controller and the device. (Some non-standard controllers behave differently, e.g. special charging ports on some laptops.) This is the reason why some totally drained devices won't charge when connected to a computer but do when connected to their charger. The charger has passive electronic components to advertise its abilities to the device; I thinke that there's a standard in the works or already established due to EU regulations that all smartphones must be chargeable via micro USB B. onnectors.
The iphone charger does 1000mA, the ipad charger about 2A
