I was given a Mac Powerbook G4 for free, however it has a couple issues that are keeping me from being able to use it... first...The battery will not stay in the slot, but I am ordering an AC adapter so that I can dock the laptop for the time being... second (the biggest problem)...the hinges that hold the screen to the laptop are both broken, so the screen is just held on by the wiring. so my question is, what can i do to fix the hinges? ive been checking eBay for some replacement hinges but no luck so far. is there a website someone might know of that sells parts for this laptop? any help would be great.
