Battery charging LED blinking

My acer laptop charging adapter is not fixed (moving a litle bit when plugging in) because some of the material which restrict the degree of freedom(fix it so it can't move) was broken. Ended up with blinking light and not constant charging (I need to try moving the charger cabel on the plugging side and when play with it back and forth or turn it around in order to find the touch spot it starts charging but after a while it starts to blink again) . So I opened the laptop fron inside and found that one of the smale cables is not rightly attached and so I found a solution by attaching that cable with the body of the charging adapter (found out that the body of the charging adapter is connected with the same pole) and by this it still blink some times but in certain postion it charge without blinking which drives me crazy, like I'm certain it is 100% the electrical surfaces are connected therfore electricity should go through. Any help would be appreciated.
