I have been needing to get a new battery for my Dell m140 laptop but
have been putting it off. Now, I notice that sometimes when I plug it
in… the green light on the adapter is on and everything is fine, after a
short while, the light goes out and before long my battery is nearly dead
but the AC adapter will no longer work.
I’m trying to figure out whether I just need a battery or if the problem is
with the AC adapter.
Thanks!
