It sort of feels too complex and very broad for me. I'm taking a look ahead in your next post, I'll attempt to get the dangle of it!

Expain why my apple supplied charger and charging cord, plugged into a normal house electical box, still indicates “Not Charging” in the iPad battery window in the upper right hand corner of screen.

Any corrective actions would be appreciated…

Any other suggestions. Apple store had a 3 hour wait for someone to test.....sounds like a problem to me..... Don't have a mac.

First off USB is a specification not a hard and fast rule that all manufacturers abide by. The 1.1 spec had a pitifully low transfer rate for data as well as the voltage supplied to USB devices. It was originally designed for pointing devices and externally powered devices like printers and external hard drives, cd roms, etc. The 2.0 spec brought higher speeds as well as voltage. Not all manufacturers include USB 2.0 ports on their hardware. You're not going to get a fast charge for an iPad on a USB 1.1 port. Secondly, in the effort to make computers "more green", OS developers (including Apple and Microsoft) put power throttling instructions in the OS. This includes active USB ports. Rather than having a full power USB port on all the time for a sleeping printer, the port will go into a low power mode. This is much better than the earlier USB subroutines in Windows where if a printer went to sleep, the USB port dropped the connection completely and you had to reboot or unplug the USB cable and plug it back in. Third, the iPad is not a laptop nor is it an iPhone. It consumes much more power than an iPhone and much less than a laptop. Laptops, BTW, are lousy for powering USB devices. The built in power hardware simply is not designed to support higher powered USB devices. Otherwise, there would be burn holes in a lot of khakis. Lastly, the USB 2.0 power spec is 5 V at 500 milliamps max. That means the maximum wattage output is 2.5 Watts. Much less than the 10 Watt power adapter the iPad ships with. The iPad, rather than stressing circuits being under powered, cycles back it's charge rate. Also to @shihab, yes. This is normal for iPads and iPhones that have completely lost their charge. (Although it's not totally drained) It's a defense mechanism against completely being discharged and loosing data from a sudden surge of electricity. Once there is enough charge to power the device and keep charging, your iPad and/or iPhone will spring back to life. In addition to administering 4000 computers (mostly Dell and HP) at work, I own several Macs (iMacs, Mac Minis, Mac Pros) as well as several Windows based machines (Dell, Asus, Gateway, and Fry's specials). The USB wattage on all the Windows machines vary and even from port to port on the machines. It's all about the manufacturer. Cheers! The Mac Tool Greetings iPad lovers and Apple haters!

While under charge there is no sign of light or something while charging and the scree is totally dark blank. Is this normal? or there is a batterry problem . Hi there

I plugged my powered USB that came with I pad and started to charge when the battery was gone off completely. While under charge there is no sign of light or something while charging and the scree is totally dark blank. Is this normal? or there is a batterry problem .

I think iPad soon will come up with new charger and we all gonna buy it :) And it is gonna cost 45$. That is marketing ) That is indeed rediculious.

Normal charging requires 10W of power, and some USB ports do not support this level, particularly with older design (design date, not manufacturing date) or inexpensive computers. For such computers, charging from 0% may take 12 hours or more rather than the usual 5 or so, and may require the iPad to be off during the charge. In such cases, use the wall wart charger, or, yes, buy a new computer which meets the latest spec. For myself, I just use the wall charger. @Annoyed iPad owner: The speed of charging depends on how much current the USB connection provides.

I am aware this was not an exceptionally critical topic, but I do recognize what you said. I will be reading your weblog far more generally.
