Well, some time ago, the power brick on my laptop started acting up. Sometimes I'd connect it and it would charge, sometime it wouldn't. I thought it was a short in the power brick so I severed the old connector that goes to the laptop and soldered on a new one on.. I made sure I matched the polarity, but it seems to not be the problem. Now every time I connect the power brick to my laptop, the connector sparks on the laptop and nothing... There is a short and the power brick shuts down until I unplug it from the laptop (but still in the wall). I've tried both polarities (thinking maybe i did it wrong) but it doesn't seem to help. The laptop works perfectly fine, but since I can't charge it, I can't turn it on... I checked took it completely apart and looked at the PCB and I don't see any shorts anywhere!! I thought maybe the power connector on the PCB might have had a short so I replaced it and solidered another one on there, but it still does the same thing. I even got a new power brick for it and it does the same thing! HELP! Im out of a perfectly good laptop! Is there any way I can tell where the short is occuring? Anyone have any engineering or electronics experience that could guide me to a way I can get it fixed? It seems like such a waste, everything on the laptop works perfectly except for the charger/charging mechanism.
