MacBook Battery Icon Shows X, menu says "no batteries installed"
- Macbook only runs on power adapter... when unplugged it shuts down immediately. Does not run on battery.
- Battery works in another MacBook just fine; 2nd MB's good battery has same issue in the broken MacBook, so I'm thinking it isn't a bad battery issue.
- Tested multiple magsafe power adapters; all react the same way... green light, no orange to signal charging. Battery indicator in top right tool bar (by clock) shows an "X" in the icon. Clicking on the menu say: "No Batteries Available"
- reset the SMC = did not fix issue
- reset the PRAM = did not fix issue
- reseated battery in case = did not fix issue
- checked magsafe adapter for debris, bent/missing pins, etc. = did not fix issue
- purchased and installed a new Battery Connector (Energy Star MacBook) = did not fix issue
- updated battery firmware to 1.2, 1.3, and 1.4 = did not fix issue
Next Troubleshooting Things to Try: (please let me know if any are unnecessary)
1) place battery in refrigerator for 1 hour to "reset" it...then try replacing in MB and connect power adapter. I have seen one person say this fixed his MB battery X issue.
2) call Apple for replacement battery (not sure it will help as my good MB battery doesn't work in this MB either, and the battery from the broken MB works fine in the good MB)
3) purchase and install new MacBook DC-in board (I've done this on an iBook before), which might help the MB charge the battery... but seems like if the DC-in board was broken now, that it would not provide power at all.
4) replace logic board (ugh.. at $800+ it's best to just suggest a new MacBook for my client)
Please let me know if you think of any other ideas or have a solution suggestion to this problem. Thanks.
