Troubleshooting for your laptop battery that would not charge should be done before bringing your laptop to a service center, or buying a new laptop battery. Just follow these instructions below to pinpoint the cause of the problem in charging your laptop batteries.

First, make sure that the problem is not with the laptop charger. Remove the laptop battery from the laptop. Plug in the laptop charger directly into the battery-less laptop and try to see if you can power up the laptop. If it does not power up, and not even a single indicator light turns on, then the problem is with your laptop charger. If you have a voltmeter, test if there is power being produced by the laptop charger. Also, test if the power cord has no breaks along the line, and that power is not disconnected from the power source up to the output plug.
