no, you cant’t do that! We have been talking for years about the fact that replacing ports from “block type” to “plug type” forces certain behaviors ... including the need to disconnect the power supply to CONNECT connectors. You can always do it at your own risk, but don't write later in your posts that it "fell and didn't turn on". If you don't feel like plugging in the batteries, unscrue or taking the motherboard out when serviceing, maybe you should take that to a good repair shop. They will certainly do it right there.
It's a pleasure to repair your own device. Repairing someone's device is primarily a responsibility.
