I have an original MacBook, circa 2006 (Model Identifier MacBook1,1/Intel

Resolved Question:

I have an original MacBook, circa 2006 (Model Identifier: MacBook1,1/Intel Core Duo/2 GHz/L2 Cache (per processor): 2 MB/Memory: 1 GB/Bus Speed: 667 MHz/Boot ROM Version: MB11.0061.B03/SMC Version:1.4f12). The original battery will not hold a charge, but the computer still performs fine using the power adapter. I bought a replacement battery (exact same unit: Model #A1185, 10.8V---5200mAH/56.1Wh, Li-ion), but when the new one is installed the computer will not stay on -- whether the power adapter is plugged in or not. I had the vendor replace the new battery with a second unit, but the same problem occurs. What can I do?

OSXpert :

Hi, my name is Britton. Are you available?

Customer :

Let's do this.

OSXpert :

Sounds good -- what does the battery indicator (upper right corner) say when it's plugged in?

Customer :

On thie computer in question right now, old battery installed. The indicator says "charged".

OSXpert :

okay, put the new battery in and see what the indicator says

Customer :

Don't I have to power down to do this?

OSXpert :

Not as long as you are plugged into the wall (assuming you don't have any issues when running off of AC power exclusively)

OSXpert :

oh wait -- just re-read your prob description...

Customer :

That is the issue, my friend. Computer won't stay on when new battery is installed, whether power adapter is plugged in or not.

OSXpert :

computer won't stay on at all with the new battery? Whether running on AC power or just the battery?

OSXpert :

gotcha...

OSXpert :

there are a few things we can try -- but they are going to involve you having to reboot the machine and such...first, bookmark this page so you can come back to me...

Customer :

Bookmarked...

OSXpert :

alright, let's first try resetting PRAM...one sec

Customer :

Did that multiple times last night...

OSXpert :

Okay...no dice I take it?

Customer :

No dice.

OSXpert :

Alrighty -- have you tried resetting the SMC?

Customer :

Explain.

OSXpert :

You need to turn off the system, remove the battery, remove AC power...then hold the power button for about 10 seconds

OSXpert :

Then put humpty dumpty back together again and power it back on

Customer :

...with the new battery? (which is fully charged, BTW)

OSXpert :

Well, perform the steps with no battery...then insert the new battery and see if it fixed the problem

Customer :

OK. Saving this chat and exiting before powering down, yes? Then when I come back up I go to the bookmark and we'll continue (or I'll congratulate you)?

OSXpert :

yessir, I'll hang out in this chat...let me know how it goes

OSXpert :

Any luck?

Customer :

Sorry that took so long. Initially it snapped off during the first re-boot, but then I cleared the PRAM five times and it's stayed on since. But the internal fan has been going since then -- hope that's not a bad sign.....

OSXpert :

Hmm, well, it's staying on now with the new battery?

Customer :

So far -- looks like 20 minutes. Battery shows a 95% charge -- do you mind staying with me while I try taking off the power adapter and see if we can work without AC power?

OSXpert :

sure thing

Customer :

Very interesting -- AC adapter is off, but the icon upper right still shows the unit as on the charger. Still functioning, though.

Customer :

I think I'd like to reboot one more time to make sure something hinky is not still going on. game?

OSXpert :

sounds like a plan. Also, did you end up clearing the SMC when you powered down last time?

Customer :

First thing I did. Probably a combination of the two that got us back to functionality. Back to you after the reboot.....

Customer :

Alright, that was weird. The screen blanked when I told it to shut down, but the internal fan didn't go off. Wouldn't reboot, and the LED indicator on the AC adapter wouldn't come on when I plugged it in. I had to unseat the battery to totally power down. But then I put it back together and we seem to be in business. Batt icon shows us at 93% and charging when AC adapter is in, and changes when I take it off. Knock on wood, but I think I'm functional.

OSXpert :

Hmm, definitely some strange events, but, it sounds like your system is stable.

If you have another issue, reset PRAM and the SMC one more time -- usually when the system gets into a weird state like that, resetting the two will get things back in order again

Customer :

You earned your money, friend. Thanks.

OSXpert :

Thank you. Let me know if you have any more questions or need more advice

  • Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill Bill M. Schenectady, New York
