|my compaq presario 2500 shuts down on its own whenever i put the battery in|
Wouldn't you think you answered your own question? Sounds like the battery is dead.
but this morning i tried to turn it on the system came on, but the screen is not displaying.
Possibly the power supply has also died, even if the light is on, it does not mean that the adapter is putting out sufficient power. We have on idea how old the laptop is.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
