So your laptop "fell down and can't get up" !!! 
You said, "some of its jack(s) were broke..." Do you really mean more than one or just the Power connection jack?
Is the jack loose and wobbly? Is the male (cord) end OK?
It is possible that the repair can be made without buying a new Jack/Socket, if the damage is that the connections are only broken loose from the circuit board.
No matter what the case though, you are probably going to have to disassemble the laptop down to the MOBO level to check and/or repair the damage, and then resolder the connections, and secure the socket. Based on your original question, that may be a task that is somewhat beyond your skill level.
So don't worry about buying the part until you determine whether or not you are up to the total repair task!!
