Should an ipad2 automatically charge when connected to a laptop? Mine says "not charging".
 
If its the same as iPad 1, it only charges while in sleep mode when connected via USB to a Windows laptop/PC. Only on a Mac does it charge while on via USB.
 
Had the same 'issue'.

It actually is charging - or just keeping the current charge steady as it did not run out of steam the entire time it was connected to a PC.

Only when connected to the A/C outlet the display actually indicates that it is charging.
 
Yes since USB only supplies 1A at 5V, it will charge, but slower.

I also noticed my iPad charges much slower with an iPod cable than with the iPad cable (plugged into an iPad wall charger). That means there's a difference between cables too!

That I have not noticed. I switched to an old ipod cable because the smaller dock connector is a pain with the case on my iPad.
 
OK it's a black belkin cable that looks kinda flimsy. With the iPad charger and cable it takes about 2 hours to charge my iPad.

Yes, the one cable transports electricity slower, the thicker one much faster, isn't that kinda logical? And the iPod comes with a hyper cable, it excellerates the electricity to hyperspeed and superstrength. That's why your iPod is also much louder than the iPhone because it was pumped up with hyperpower.

Roflmao, back to being serious, they are all the same cables, same mfr. part number.

Note the identical part number MA591G/B

Be careful with Chinese cables though, they don't support ultra power.

Synaesthesia, are you sure you are not confusing it because of the chargers? The iPhone charger has 1A output wheres the iPad2 charger has 2.1A output

No, I know about that. I don't think it's a common occurrence though, this cable is particularly old and loose-fitting. I noticed it charged my iPod slower too.

My MacBook has one high-powered port and one regular USB port.

My iPad 1 says "Not Charging", but when you unplug it you can actually see the battery level has increased
 
I think it doesn't charge with the screen on, it draws too much power, but charges with the screen off.

If your standard USB port supplies 1A then it is running out of spec, but if you have a very new port then it may be able to charge, but will not be able to do comms at the same time.

A maximum of 5 unit loads (500 mA) can be drawn from a port in USB 2.0, which was raised to 6 (900 mA) in USB 3.0.

USB 2.0 standard-A connectors are rated at 1500 mA by default. A Dedicated Charging Port can supply a maximum of 1.8 A of current at 5.25 V. A portable device can draw up to 1.8 A from a Dedicated Charging Port. The Dedicated Charging Port shorts the D+ and D- pins with a resistance of at most 200 Ω. The short disables data transfer

Read the card that came with the Ipad, 10W (watt) charger needed to charge the ipad, in other words the charger that was in the box. All other chargers will work but much slower, including when connected to USB 2.0 and 3.0. As far as I know the iphone charger is 5W.

Watt = joule per second. the rate of energy conversion.
