It is important for a notebook computer to sustain its battery charge. If your battery indicator keeps showing a 0 per cent charge, understanding what may be causing the problem is essential to its usage.

Operating System

If the power indicator says "0%, plugged in, not charging," this may indicate a problem with the operating system. Shut down the computer, unplug the power adaptor, remove the battery and wait for at least one minute before inserting it back into its compartment. Turn the notebook back on and see if the power indicator status changes. If it is no longer showing 0 per cent, it may be that the notebook was charging the entire time, just not responding to the operating system and therefore showing an incorrect battery reading.


If the battery indicator is showing 0 per cent, the power adaptor may be supplying power to the notebook but is failing to load power to the battery. Try disconnecting the power adaptor and see if the computer shuts down. If it does, it indicates a problem with your battery.

Power Adapter

Ensure that the power adaptor is plugged into an active power outlet and the power port of the notebook if the battery is showing 0 per cent or is not charging. If the power outlet is active and the connection between the power adaptor and the notebook is properly secured, but the battery is still not charging, the notebook power adaptor may need to be replaced.
