I have a HI GRADE SADP-65KBC , and it only working off the battery at the moment, the Jack socket is not lose, I am using the right charger, and do not know what wrong with it it just will not charge the battery
hi well seems to me that there's a problem with one of these components here as one has to be faulty, i would check another adapter first before assuming that its the jack socket as its either one or the other.
I have seen a broken solder connection on the Mobo before
But to prove this the entire Mobo must come out !
Otherwise test with yet another power adaptor. Actually many local computer tech shops (not the big retail stores though) carry different charges (voltages and plugs) for different laptops. Maybe ask if they could try one on your computer (I would )
