BUSTED POWER CONNECTION ON MY G4. I dropped my Power Book directly on the power supply corner! Answered

 Had to buy a new power cord (big bucks!) The drop also mangled the frame around the computer connection hole.  I have to push, turn, giggle, etc to get the green light to come on. Now I can't even get that, except for a few seconds. Do I need to mess with the hole opening to get a better connection? Does the round sheath part work as the negative?  Any suggestions will be great!

There are two ways you could fix this.  ONE way, is if you want it to look like factory new and you dont want anything that looks "RIGGED" or imperfect. If that is your personality, you  should get professional repair.  Personally, I prefer the SECOND kind of repair.  Take the unit apart enough to access the damaged area.  Examine the damage carefully for several minutes untill you formulate a plan to correct it by WHATEVER MEANS NECESSARY.  If the case and connector are damaged beyond repair.... run a separate power wire soldered directly to the circuit board.  BE SURE to follow polarity plus and minus connections carefully.  REMOVE the battery before soldering to any battery powered PC board to avoid further damage.  BE SURE to attach the wire in such a way that STRAIN RELIEF keeps wire from pulling on delicate PC board foil traces... in other words, if someone PULLS the wire, it wont tear off a piece of circuit trace again damaging your item.  When you are done, it won't look factory NEW but will be back in service again.... and your wallet will stay in your POCKET !!!   You may discover that all you need to do is RE-SOLDER the connector and put the case back together!!! Good luck with it...

 Thanks for all the replies.  Framistan hit the nail on the head for me.  Although I took out all the little screws, including the ones in the battery compartment, and I still could not get it apart without, what I considered, too much stress.  I was afraid I'd break something else! BTW the new power supply worked just fine, with minimal "fiddling" with it - turning it, pushing it in a little harder, etc.  It just got harder and harder to get the power to connect.  Now only very rarely will I even get a "green light".  Any more suggestions about getting the upper and lower case parts separated?

Pull the thing apart and break out the multimeter, Did you hear a distinct "SNAP" as you dropped it, if you did you may have severed a trace however it is more likely that you broke the connector off, the most you can do is take a look, or send it to a repair shop.

You need to take it apart and find what's broken, then look at fixing it.

I don't own a Mac but I'm going to guess that it needs to be opened up and at a minimum, have some connections re-soldered. There may even be a break in the board that will have to be repaired.

Seconded - the barrel connector could be damaged, the barrel's soldering to the mobo, or the mobo, or any combination of the above...

its expensive, and poopy.
