    Dell PA-3E Dim LED

    I have a Dell PA-3E power brick that the LED light on the laptop plug is dim on. The brick otherwise works (charged and powered a Latitude D630 no sweat).

    Where should I look? Bad cable? Known problem?

    did you wiggle it?
    Just cook it! It's already broken.

      do you mean the laptop socket?
      i'v never seen one on the charger plug.

      maybe it's just a failing led if the laptop runs & charges.
      it happens - it's rare, but it used to be pretty common.

        Also it might be that the caps are going bad in the charger..

            then maybe the old "broken cable at the brick" problem?

              Perhaps. Looks like the old hammer and utility knife blade trick is in order.

                Same thing happened to mine, Dell overdrive the LED to make it bright but it last far less time than it should.

                  Yup. Cracked it open, minus some lelon-ish caps on the secondary, I didn't see any issues. given that only 3 wires go to the cable, the LED(s) and resistor are internal to the plug.

                  Noted on the overdrive... I may save this to power a port replicator or something. I was going to use it with my E5530 I just bought w/o AC adapter, but I can just one of my shrinking stash of PA-10 bricks.
