Re: Dell Latitude E5450 Power Short Circuit

I got a short circuit situation as well, with the charger plugged in, LED on, plug it into the laptop DC jack, LED goes out. All the posts I've seen point to the bad motherboard. If anybody has any idea on how to troubleshoot and replace the diodes/MOSFETs, I'd like to fix it myself if possible, but if I can't I am wondering if I can replace the motherboard, part number ZAM71 LA-A903P(the bad one I have with the i7), with a ZAM70 LA-A901P(i3 or i5 I think). Also can i take out the i7 CPU and put that in the ZAM70 LA-A901P board? Thank...
