It don't matter eather way.

This should not damage the laptop at all, they are designed to be turned on at any time. (Unless of course the battery is dead.)

To charge a camera battery with USB, you can typically connect the camera to a USB power source using a USB cable. Make sure the camera is turned off while charging. The battery should start charging once connected, and you can check the battery indicator on the camera to monitor the charging progress.
To check if your Sansa Fuze is charging, look for a battery icon on the screen. When connected to a power source, the icon should display a charging symbol or animation indicating that it's receiving power. Additionally, if the device is turned off while charging, it may briefly show a charging screen upon connection. If the battery icon is not changing or remains static, it may not be charging properly.

No, these types of batteries are not technically able to be recharged.
try charging your battery or maybe you completely turned off your ipad
There are different things it may mean. My macbook said that it wasn't charging even though it was plugged in, and it turned out that the reason was because the charger was plugged in the wrong way :) (the charger should be facing out, away from the laptop)
Automotive Battery VoltagesAssuming your voltage meter is accurate, the battery is fully charged, when the key is turned on, without the engine running, and no accessories turned on, the meter indicated voltage should be 12 volts. When the engine is running and the alternator is charging the battery, the voltage should indicate anywhere between 13 volts to about 14.6 volts.Answer 2 - A wider Acceptable Range13.5 −16 volts is acceptable with the engine running.
The Battery, if you are meaning electrical charge in a laptop?
All batteries will drain a small amount, even if they are not being used. However, a substantial battery drain would be due to a problem with the battery or laptop. Make sure that the laptop is indeed off, though. With Vista, clicking the power button in the start menu will not shut down the laptop, but will instead put it into sleep mode. This continues to drain the battery. Some of the lights on the computer will still be lit when the laptop is in sleep mode, while no lights will be on if the laptop is turned off.
