Laptop Battery Dead Symptoms

You can do a few things to check the battery symptoms and see if it needs to be replaced. The first thing you can do is check the light on the charger. If the light is green or orange, the battery is probably fine. However, if the light is blinking or not lit, the battery is most likely dead. Another symptom of a dead laptop battery is if the computer will not turn on when the charger is plugged in. Finally, you can also try connecting the laptop to an external power source to see if it will turn on. Suppose the laptop does not turn on with an external power source.

A laptop battery may be dead if it exhibits any of the following symptoms:
It will not charge.
It charges slowly.
It does not hold a charge.
The laptop does not work when not plugged in.
The laptop only works when plugged in.
If you are experiencing any of these issues, it is time to replace your battery.
