X in Battery icon

Macbook Pro 1,2

2.16 Ghz Intel Core Duo

Running 10.6.8


Coconut Battery has N/A for everything except Mac Model (Macbook Pro 1,2) and Age of your Mac (77 Months)


When the Magsafe adapter is connected it is orange. The computer runs when it is disconected. The computer will not boot up without the magsafe connector connected. I'm currently leaving it on and unplugged trying to run the battery down.


I've removed the battery and re-installed - Sill had an X

I've reset the SMC and still have the X

I've reset NVRAM and still have the X


After 1 or 2 reboots (and the magsafe connected) I did get the charging icon with 0%. It went back to an X after 20 or 30 seconds. Immediately after booting and showing the 0%, About this Mac shows a battery is connected. When it goes back to the X and I refresh the System Profile page, it says No battery installed.


I bought this computer used and I've had it for approx 2 years. Haven't had any issues up till now. I installed more memory the day I bought it and replaced the harddrive (needed a larger one) about 18 months ago.


Any help is appreciated.

It just died and I plugged it in and rebooted. Battery icon says 0% and charging.


System Profiler .... Condition says Normal. Charging - Yes, Full Charge Capacity 5657, Cycle Count 0, Amperage 0, Voltage 0.



Coconut Battery has all 0's except Battery temp will show 36 deg and then 0, then after a while 36 ad then back to 0.


In the time it took to type this, Coconut now has all N/A's and I have the X back in the menu battery icon.


We haven't had any battery issues until today.

As you may know, all modern lithium batteries come with a miniaturized management controller to prevent overcharging, overheating, etc. The Mac's SMC talks to this "mini computer" to control power thorought the system. In this case, it appears that they are not talking anymore. Either the battery fried or the communication channel (one of the wires in the battery connector) went kaput.


If you want to restore functionality, battery replacement is inevitable. Then you'll know which of the two options occurred. If the battery profile should remain blank after replacement, then the Mac has bigger issues, but I have high hopes that will not be the case. Yeah, you could waffle and delay replacement, but know that your data will be at risk every time there's any kind of power failure, cause you have no idea what the battery is up to.


With your model number, check in PowerBookMedic.com, IFixIt.com for parts, prices and DIY's.
