Hello all. Needing to replace the DC-in/USB jack on a PowerBook G4. It is the 1.5GHz ALS model. From looking around on eBay, I see a bunch of DC-in boards that look exactly the same, but with differentiating part numbers and prices. Does it matter which one I buy, as long as it fits a 15" 1.5GHz PB and looks the same? I do not see where the difference is on these besides the part number. If you have any info on this please do share. Thanks in advance!
