How do I reset the onboard chip to my MacBook battery?
I recently purchased a used A1181 first generation MacBook Core Duo 2.0 GHz black. I got it for a good price because the battery would not charge, but the computer worked perfectly otherwise.
I brought it home and started to mess around with it. The mag safe light was green and allowed me to operate the computer. If it gets unplugged the computer immediately shuts off. The battery indicator icon in the upper right has the charge symbol and it shows 0% for the battery.
I don't have it on at the moment, but I remember that it only had 131 charge cycles. To me it sounded like the previous owner had left the computer in sleep mode on battery power for too long and that it completely discharged itself.
I had also removed the battery and put it back in while the computer was plugged in. A few times I saw the orange light come on at the mag safe connector but it quickly went back to green.
Relevant to this question, I also was recently given a used XBOX 360 controller with a rechargeable battery. When I plugged the charging cable into the controller, it would light red to indicate it was charging, then after 3 seconds or so it would go to green to indicate that charging was complete. The battery would only work for a second before shutting off. So I found this video: http://www.youtube.com/watch?v=QXaIlyjvv...
it gives instructions on a way to short out the battery and reset the onboard chip. I tried it and it actually worked. The battery fully charged overnight and I was using it this morning.
So back to my question. I'm not going to just randomly start shorting out connectors for my MacBook. However, I think that it should still have life left in it at only 131 charge cycles. Does anyone know of a similar trick that can be done to reset this battery? I'll take all responsibility and will do this in a safe environment with all precautions. I've worked with electronics before and I just wanted to see if this were possible. I can't find any pinouts for the battery itself for me to guess either.
Es esta una buena pregunta?
