Unit went off after battery discharged.
First the Battery Icon in the top bar said BATTERY NOT CHARGING.
The machine continued to work until the battery ran down. This was during the ADAPTER being PLUGGED IN.
The Adapter connector showed ORANGE but not charging battery.
Replaced with different battery and unit booted up and ran until that battery went down.
Now not having the means of charging the battery and the machine not working from Adapter it is out of use.
I have replaced the smal DC board where the power adapter plugs in.
Then when connected to Adapter the light was green, orange and then briefly RED before it went off. That adapter still works with my other PB.
So question is...
What could trhe matter be and what cost would be involved for the part(s)?
Other than this the machine is perfect with a recent Apple replaced Screen (due white blotches and under Apple CAre)...
Is this a good question?
