There's a link for taking apart and fixing PB 5XX batteries, but be warned you have to cut open your batteries to do it! http://www.wwc.edu/~frohro/520_Fixes/520_&_540.htm Definitely try the software fix first--this seems to bring back apparently dead-as-doorknob batteries. To fix the right battery in your PB 5xx (if you have 2, you'll have to fix the first one, then swap the second one into the right bay): 1-Download a copy of VST's Empathy and a copy of Apple's PB 5XX Battery Reconditioner. The first few times you run these utilities, nothing will happen, but don't worry about it. 2-Zap the PRAM by restarting the PB while pressing the command, option, P and R keys. Wait untill the PB chimes two or three times, then release the keys. 3-Shut down and reset the PB's power manager by pulling the batteries out, unplugging the power cord, and pressing the power, option and control keys simultaneously for 45 seconds. Don't know exactly why this works with the power off, but it does. I had an Apple tech once tell me that it drains excess electricity from the circuitry, whatever that means. 4-Put the right battery in, plug in and restart. 5-Run the VST Smart Probe, then try the Reconditioner. If the PB doesn't recognize the battery, repeat all the steps above except zapping the PRAM. You may have to do this numerous times (I think it took six to eight tries for one of my batteries), but the crucial thing is to pull the battery out each time you restart. This enables the VST software to give the battery a slight charge each time, and after enough of these, the computer will recognize the battery and begin charging it. Good luck, Don Silver John H. wrote: I downloaded the Intelligent Battery Renewal and it does the precharge but then tells me to return the battery to Apple. I thought I found a link to the Lind software BU 500 Deluxe, but the server is down just now. Were you saying that there is a VST battery utility as well? And no luck searching for battery rebuilders or any other query for used batteries. Any links there? ===== __________________________________________________ Do You Yahoo!?
