Why My IPad is “Not Charging” Tweet

Apr 6, 2010 ipad problems

Since the day iPad was launched there have been many issues coming up like Wi-Fi problems , overheating , inability to handle IMAP from Yahoo and many other email service providers , charging problems , most of these are design / hardware issues causing a cloud of confusion amongst users and doubts of having acquired a defective device .

A day later Apple explains why the device shows not charging notification when charged through a computer and how it could be resolved

As the iPad has hefty power requirements when compared to the iPhone’s and iPod’s thus it requires a high power USB port , these are generally not present in computers like older Mac’s and Windows. In case you connect you iPad to such computers (low powered USB port) it would show Not charging in the top right corner but that doesn’t mean that low powered USB ports cannot charge the device , charging will only take place when the device is put to sleep mode otherwise this power will be used for device operation and there will be no dissipation of battery power, so its like your iPad is running on DC power from your computer. In this case it will take a longer period of time to charge the device equally, and you can see a notification of charging while in sleep mode as said by Apple.

For faster charging you can use iPad’s 10 watt USB power adapter , or use a USB port of recent Mac’s where your device can be charged and used altogether , so you don’t need to send your iPad to Sleep .

Here is more about what apple said in technical terms:

The USB ports on Apple computers provide 5 V (Volts) and 500 mA (Milliamps) to each port, regardless of whether the port is USB 1.1 or USB 2.0. This is in compliance with USB specifications. On some newer Intel-based Macs, such as the MacBook (13-inch, Late 2007), when a device requiring more than 5V and 500mA is connected, the port with that device connected to it becomes a high-powered port capable of offering up to 1200 mA at 12 V. That port will continue to operate as a high-powered port until the device is removed.

In short there’s nothing wrong with your iPad its just hungry for power, and needs more power than what typically your USB ports provide. So if you have the latest Mac you would never see such an error , but for Windows users USB charging is not the best option , instead go for the 10watt USB power adapter to charge up your iPad.
