Verify the battery's charge level by pressing the battery's power button. The battery will then show its charge level via the red LEDs. One or no LEDs means a low level, whereas four (or five for the V72) means a fully charged battery.
If 1 or no LEDs show, charge battery from wall or solar panels.
Confirm voltage setting
Check the AC charger that came with your laptop for the "DC Output" Here are the most common voltages and the appropriate setting on your battery.
12 -> 12V
14.5 - 16.5 - >16.5V
19 - 20.5 -> 19V
Unplug and plug in the output cable. The light above the Voltage Indicator should turn on.
Next, connect to your laptop and check that the cables are secure. If the adapter seems not to connect firmly to your laptop, you may need to try a different laptop adapter.
Power shutting off?
If the Voltage Indicator light turns off after connecting to your laptop, your laptop may be drawing too much power.
Reset the laptop by connecting to a power source. Then try charging the laptop in sleep or off mode. This happens most often in power hungry laptops including some versions, but not all, MacBook Pro 15".
