Need some help with a laptop part....PAGING LIPPSMAN

My laptop charger is acting funny

Dell Inspiron 1520

This charger

When I plug it into the wall, the green light on the "rectangle piece" hasn't been coming on immediately lately ( and I have no charging capability )

I mess with the connection by the "rectangle piece" and sometimes I get power, others time I have to mess with it more.

Any vendors out there sell this over the counter that you know of, or do I have to buy it online and pay shipping?

Any help is appreciated 

PS

APK will ignore all the taunts of people hoping I can't get online for a very long time

You will need to order it, but you could get one of the universal ones from the Shack.  Just e-bay the thing, but try to get an actual dell one instead of one of those cheap ones.

Thanks Lippsman

Any idea what went bad?

I assume the guts of the rectangle thing is like a power converter / adapter....do they just wear out in time?

Thanks for the reply
