My brother’s laptop has the magsafe connector broken at the laptop’s end.
We tried soldering the powercord of the adapter directly to the board where the magsafe connector
is also connected to… We figured out that pins 1 & 5 are the ground and 2 & 4 the supply. Pins 3 seems to control the led on the connector.
So we soldered ground to 1 and the positive to 4, but it seems not to be charging this way.
Should pin 3 be connected as well ? (maybe the charger-side connector has some circuitry build in to control the charging process ?)
Any help would be greatly appreciated
