Changing the Battery:Apple support said it COULD NOT BE DONE!
10 - 45 minuten
The IMAC PRO 2009 model Battery was no longer charging though it was still working from the power cord .
I looked at all options including replacing the Mac
After watching the video tips.. I remembered what i had to do.
It took me less than 10 minutes to change it ..half of that was chat ting to my friend:)
It was just too to easy to believe.
Get onto the website and youtube that advise you on how to fix the problem.
you're battery may not be totally gone like mine ..but try the options.
if you know there are no options left other than discarding the mac
Go to IFIXIT Site and order a new battery.
They'll advise you on what you need and how to replace the battery.
It costs $138 for a new battery and little bit of time
By the way ..for Aussie's and maybe other countries it cost more due to the exchange rate $250 But It was definitely worth it.
Apple Tech's would cost more and so would a New mac.
The only pieces of advise is :you will need 2 x screwdrivers ..one for the casing which is a really tiny screwdriver.
and the one I purchased for the battery screws.
The other advise is "DO IT" ..Replace it yourself!
It was easiest thing I have done in years.
its working perfectly now!
