you must use a battery charger that contain a USB port and connect it to the laptop's USB port
Your laptop is unable to charge because of a problem with your adapter or the battery itself; try plugging out the battery and returning.
depends on the how u maintain the laptop and don't charge the battery for hours to gether when ever it necessary keep the charge >
There is a battery inside of it, and he only way to charge your camera is to charge the battery with a battery charger that plugs into the wall...look on google, you'll know how.
No
It really depends on the camera! If you have a cord with a plug for your camera and a plug that fits in the computer most likely it will charge!
Most often, yes. But... it would have to be in contact with the battery charger. There is no way I know of to charge a camera battery without it being in contact with either the camera or the charger.
No It will give the laptop an overload and will wreck your laptop. Do not do it.
If it is a desktop, no. If it is a laptop, yes, it has a battery and you charge it in the wall.
No, It is not recommended to charge the laptop battery yourself. Laptop batteries require specific charging circuits and power sources. Attempting to charge it manually can be dangerous and may damage the battery or the laptop. Always use the manufacturer's recommended charger and follow their instructions for proper charging.
Your battery will lose charge faster.
Most likely because you have left your laptop on charge constantly without it needing charge causing the battery within the laptop to become instable. (basically replace the battery)
No, the charge in the battery is a change in state of the battery contents, not an addition to the battery.
