According to the experience of the small series iOS device can not open the problem is likely to be the case of electricity, the card has crashed, the system crashes, the following small series on these issues to give you introduce different solutions.
One, system crashes
If none of the above solutions work, and you see an itunes connection on your Ipad/ipad air screen, the phone is now in recovery mode.
Method One: Official restoration
Downgrade Description:
This method is useful for operations when the latest iOS8.1 system validation is not closed
Operation Steps:
1, the iphone ipad ITouch and other devices connected to the computer to open iTunes.

quad-core processor. At the press conference, the answer to this question was finally revealed. Apple's new iPad uses a brand new upgraded Apple A5X processor.
Apple A5X dual-core processor
Although Apple did not deliberately emphasize the hardware performance of the processor during the press conference, it is estimated that the apple A5X processor uses a dual-core architecture based on the model. However, consumers do not need to be disappointed.
In addition to exposing the more details of Apple Watch and the new MacBook, we did not see the ipad Pro, which was rumored to have been reported before the press conference, and how much it was disappointing to see the ipad's new Apple powder. However, the inaccurate news is that Apple has postponed the launch of the ipad Pro to this September. But since Apple has launched a new 12-inch MacBook, will the

South Bridge Chip (South Bridge)
It is an important part of the Motherboard chipset. Generally, it is located at the far bottom of the motherboard from the CPU slot, near the PCI slot. This layout takes into account the many I/O buses it connects, A little farther away from the processor is conducive to wiring. Compared with the North Bridge Chip, the data processing capacity is not large, so the south brid
Can I replace my laptop with my laptop?
Based on my actual usage requirements and experience, if you use a notebook to record meetings or perform general document processing, this kind of work can be completely replaced by iPad.
The biggest advantage of using iPad as a portable computer for office is its high portable performance. For example, one hand holds the iPad

I finally understood what the retina is like a normal screen. That is to say, the resolution is twice the size of other screens, but the size is still the same. An image is 200*200, and the image style is set to 200*200. The image is blurred in the retina. If the image size is 400*400, it will not be blurred, but it will be in high definition. The rounded corner, gradient, and shadow depicted using css3 are the same.
