Macbook 13" Penryn/SantaRosa Pram Battery Repair
1 - 3 horas
Screen would go black from time to time, then more frequently until a Pram zap could not bring it back to life. I researched the problem online and the wisdom was that the pram battery was most likely the culprit. If moving the screen created the problem, then the inverter and/or cable was the problem.
I began by consulting the local Mac repair shop who informed me (long story short) that there was not pram battery in this model and that I might as well buy myself a new computer. I had found your site, and went back to your excellent manuals and decided to order the inverter and cable. They arrived via Fedex (Tnank god it was not UPS, yiu got my vote one more time there..) and so began the repair. Once I got to the hinge, however, I found that there was indeed and Pram battery and I had to source one out. I decided to replace the parts anyway. I am still awaiting my Pram, so its not back together yet, but I am pleased with myself nonetheless.
Advice. Firstly, there are a lot of screws and they are all sizes. I suggest printing off a copy of the tutorial pages an taping the removed screws on in their exact location, keeping the pages in order. this will help when re-assembling. Secondly, the drive needs a small dab of dielectric grease. Thirdly, the foil tape betwixt the superdrive and fan really should be renewed. Fourthly, loctite is a good idea on the screws on reassebly. And lastly a can of compressed air. these are items most of us who don't normally do a computer repair might not have kicking around. A static strap is not necessary but advised and absolutely mandatory if the repair in in a carpeted room. My space is tile and wood floor and I work in bare feet.
