Battery Dead?

[LuckyLuke90]

Hello, I'm new to this forum. But I don't have an apple store near by so I hope someone will be able to help me.

Yesterday when plugging in an external display I touched the firewire port with the miniDisplayport connector. This caused a little spark and now my macs battery is completely dead.
When I boot with the magsafe adapter attached everything works fine. But the menu bar icon says 'Not Charging'. In iStat Pro and in energy saver preferences it says the current load is 83%. But when I take out the magsafe adapter the mac turns of instantly.

My question is: Could this problem be solved by changing the battery or is there something wrong with the logic board that controls which power source is used?

I've already reseted my PRAM, NVRAM and SMC.

You probably shorted out the power pins for the FireWire ports and therefore fried an important part of the logic board.

That blows. I find it odd that a spark would form, but I guess it could happen. But the previous post seems valid: you most likely shorted out a connector on the logic board. But it may only be the wire connecting the battery.

Try opening up the back cover.

Plug out the battery connector from the logic board and re-attach it

Then plug out the cable next to it(to the right) and re-attach .


This could help the computer to identify the battery

I had to replace my mid 2009 battery on 430 load cycles,
Those old batteries are only guaranteed to work for 500 cycles


i'd say replace it anyway

Thank you all for your help!

I've done what abdu2s suggested and it worked, the battery seems fine now.
I also tested the firewire port to see if this would happen again when I purchase a new battery. But it seems to have been a one time accident

Since my battery has had so many cycles I will replace it as soon as I'm not in the middle of a project and can do without a macbook for 2 weeks. (that's the time it takes the nearest service point to replace a battery!!)
