My mac book is working fine, but the battery will not change and the power meter, on the battery, don't work.

Step 1: What the problem could be

I wanted to check if the battery was really dead. I knew there is a circuit board inside, to regulate and monitor the battery temperature.

Here is how to open it and possibly fix the problem.

I must tell you , this laptop suffered from a shorted out wire before this problem. I had to replace the power cable, inside the computer, between the screen and the power supply.

I had heard of people on the web, replacing there batteries with the same problem. Before trowing out that battery, or exchanging it from a refurbishing place, have a look at the fuse.

<p>How about when the battery is fine, but the ibook simply wont start. It began as an odd behavior, it refused to start now and then, but at the last, I had to have it allways on. Accidentally someone turned it off and, never again I saw it alive...</p>
You say &quot;mac book&quot; in the intro, when it's really an iBook.<br />
when you have it apart... might as well go the extra step and clean up the rosin flux residues. You'll have someof your own, but it looks like apple's outsourced contractor did NOTHING to clean up after themselves :-)
