My sister's Powerbook recently went through some trauma. A friend spilled a drink on the computer - NO! We immediately turned it off and took it to an Apple Authorized Reseller & Service Center. We got the computer cleaned out, and thankfully it still works. The computer still works perfectly, but the display is unbearably dim. The Apple Tech says that the inverter board (piece of hardware that sends the video signal to the display) is blown, and that's what's causing the dim display. It's a $50 part that is easily replaceable, and he says the computer will work fine once that's installed. Even without that part, the computer still functions perfectly when hooked up to an external display. The spiller offered to replace the machine, and did. I had the hard drive removed from the PowerBook so I could put it into an enclosure and keep my data. Bottom line, we have a 12" PowerBook G4 1 Ghz / 256 MB / Combo / AE ready that needs a hard drive. To use it as a notebook, it needs a $50 part. Without it, it functions perfectly with an external display. How much can I expect to sell this machine for?
