I did fix laptops too back in the day, and there were basically two things that went wrong
1) the bit between the motherboard and the screen was often a crappy little flexi ribbon cable coiled around the hinge like a mainspring, it wears out as you open and close the lappy and a wire eventually cracks, your screen would only work at certain angles and then it'd die completely
2) the charging hole wears out and you have to hold the wire just right
Aye there was sometimes other stuff, but those were 90% of the problems.
The best laptops - my beloved Toshiba Tecra M4 - had the charging hole as its own whole separate little assembly that plugged onto the motherboard on an internal connector like a JST or something
So you'd cycle the barrel jack connector a thousand times, and then you'd throw away the barrel jack hole and cycle the JST connector once, like the hour hand on the life clock of your motherboard
(the crap ones had the power socket soldered to the board and it was always a right bastard to desolder 'cause of the big ground plane sucking up all your heat)
