Battery functions not working

Apple MacBook "Core 2 Duo" 2.1 13" (White-08) Specs

Identifiers: Early 2008 - MB402LL/A* - MacBook4,1 - A1181 - 2242

I'm having a hard time figuring this one out. It won't run off the battery. I've tried two new batteries. I've replaced the Magsafe board and battery connector. I do not get a sleep light. When I first plug it in I'll get an orange light for about 10 to 15 minutes then it turns green. Coconut battery says it is charging but shows 0's in all the categories including cycles. I get a -9.223372e+18% message in the box. The Apple icon shows 0 charge but also shows it is charging. Anyone with any ideas of what to try. I've zapped the PRAM a couple of times. Test buttons on the batteries remain unchanged.

Answer this question I have this problem too

Is this a good question?

It's probably the board. DC-ins on A1181s are never related to charging issues if you're able to power the machine and get a solid light. The weird numbers in Coconut Battery mean it can't get a proper reading.

Do you know the battery connector is good, i.e. have you seen it working? Lots of these end up being bad, so I'd try another...I've had situations where 2-3 in a row are bad, and the 4th works. I'd also take a look at the board where the battery connector goes, and see if there's any corrosion you can clean off with alcohol. Any maybe try to clean it up regardless. Sometimes the corrosion is on the underside of the board, so if all else fails, try taking the board out and have a look. Also, make sure to give the connector a firm push into the board, because the pins are long and these issues are often caused by it not being firmly connected. Also, make sure you're using the right screws to secure the battery connector -- sometimes if the wrong screws are used, the connector will rest at an odd angle and the battery won't fully connect.

That's really all I can think of. It's almost always the battery connector or the board in cases like this, but more often the battery connector than the board, so you may still be in luck if you try a couple more of them.

Thanks for the help. I got the board from PBM and they're usually very good. I'll pull it and check.

No problem! Funny we're discussing this, because just a minute ago I ran into one that had the same crazy numbers, and it turned out to be a bad battery, which is unusual. But I wouldn't suspect that's the problem in your case, because like you mentioned you're using new batteries that you have seen functioning?

Batteries are from two different sources. One an Apple branded and one a "In the box" Newer tech 60 watt.

Just dropped in a brand new battery connector board. Same thing, it will give an orange light for 10 minutes, then turn green with the battery not charged. I can unplug it after the 10 minutes, plug it back in an get another 10 minutes of orange but the battery is not charging even though it says it is. I still get the -9.223372e+18% error. I hate to spend this much time and money on a machine only to give it back with the old parts and not working. No dinner tonight.

Hey Rich: the only other thing I can think go is reset the SMC. If that doesn't do it, check out the power chip on the bottom of the board about an inch from the MagSafe adapter. If it's concave , it most likely overheated. Good luck

Smc reset did not work. If I put the original dead battery back in I get an X on the battery icon and no orange light. If I pull the logic board and check the power chip, is there anything I can do if it is concave? A web search for the -9.223372 code results in nothing, not even this question. I just don't want to send this student home with a Mac that doesn't work right.
