nothing will happen
yes. It is.
It turns off
Yes, it is perfectly safe. However, if there is a storm happening at the same time, there might be a chance of being shocked so turn off your computer when that happens.
Unplug it.
yes. it is best to play it off charge, and to unplug it when charged.
yes
If it is on while you unplug it all four quadrants of the ring of light turn red. All you need to do is turn it off then when you turn it back on it will be back to normal. Same thing happens when you unplug the AV cord except it flashes.
You can connect it to your computer, so it will be charging. Then iTunes will open up and you can sync your iPod and add songs.
No, it will not make any damange.. it is completely safe to play your itouch while its charging in a computer or on the wall :) ... unless if you are syncing your itouch then dont play it.. only play it if its just charging
In order to charge the tablet from the computer - you need to leave the computer switched on.
If it is charging on your computer than you can't but if in the wall than just put it in as normal, Maybe, I think when it is charging though, you can't do anything on your IPOD. Unless you sync it or something. actually if its charging on the computer or the wall u can actually put in the passcode by unlocking it but if its on the computer and ur synicinc music in it then u cant
It happens to me a lot, its a problem with the computer battery, my computer simultaniously shuts down EVEN when its charging.
