shuts down on slightest magsafe twitch
Yes, I know it’s 2021, but this is still my workhorse, with SSD and tons of RAM, cracks in plastic shell and some destruction aroung magsafe. Sorry if my story would be a bit too long.
First, the cord near magsafe plug deteriorated, started to be hot and finallly plummeted. Since it is hard to buy original power adapter where I live I went to aftermarket and got a decent quality replica adapter that made my trackpad act erratically so I just cut the cords and soldered back the original adapter and a magsafe replica cord. It seems to have a chip in it since the machine recognises the adapter’s serial number and stuff. It shows all those green and amber lights and charges battery well.
Now I can plug and unplug the magsafe cord normally, it works as designed, but when I move the plugged macbook around (being closed with a NoSleep app preventing it from hybernation) and accidentally pull the power cord slightly, the thing suddenly shuts off completely. No white light in front, no any light in magsafe. I unplug and place the magsafe back, still no light. I can boot from battery, but to make it work from the adapter I need to unplug the adapter from the wall socket and wait for some time and only then it brings back green or amber light again.
Once again, sorry for a long explanation.
Could anyone please give me some clues what’s going on ? Is it something wrong with an aftermarket magsafe plug, maybe it’s a magsafe board, or the original power adapter is malfunctioning ? How is it possible at all that macbook shuts off with a battery installed ? I taped the magsafe cord to the body to prevent it from moving in its place but hey, that’s inconvenient.
