Hello,this morning, when I plugged my Dell power supply on to the laptop, the green LED went off and red came on - swapped out power supply-still same problem -possibly a shorted protector on MB at power input?
Maybe a protector integrated into the power jack?
Thanks

Since you tried with 2 different power supplies there's probably something fried on the motherboard. Maybe check on the Dell forums you might have a better chance to find a possible solution there. But it's a very old laptop so it probably just reached its end of life.

A short in the power jack itself is a very real possibility. A replacement of the power jack is not too difficult of an operation, there are even video's on youtube showing how. 1) http://www.youtube.com/watch?v=SsNm6fmWQ8s 2a) http://www.youtube.com/watch?v=94rTbuP3txc and 2b) http://www.youtube.com/watch?v=C1TEaZI83Uc (it's a two part).
There are also companies that specialize in that repair on laptops - average fee ~$90
Hope it helps

It could also be a duff battery - does your battery last at all or does it die the moment you unplug the power? I've seen similar things (and one or two other very odd symptoms) a number of times on D600s and other Dell laptops when the battery reaches the end of its life.

The D600 is getting on a bit in years but they're still great little machines for light usage.

Very good point that I completely overlooked
