Why is my Mac not Charging Correctly?
So I recently acquired a used Macbook late 2008 aluminum. I purchased it in the hopes that I might be able to fix it, as it does not seem to want to charge. Here are some details that have made me think it is still possible to fix:
- The 85 Watt T-Shape Magsafe connection has a faint green light
- The laptop claims to not be charging, but has a positive amperage ranging from 90~140 mAh
- The battery percentage does not lower, but retains charge when plugged in during normal use
- The battery will in fact charge in small amounts when left to idle
What I have tried in order to fix it:
- Cleaned the magsafe pins on both the computer and charger
- Reset SMC and PRAM
- Various methods of reseting, and restarting
- I tried removing both sides of the adapter and plugging it back in
Here is the Battery Log File from the system settings:

I think my best bet would be to change the magsafe connector inside the laptop, or resort to just leaving it plugged in to trickle charge. Could it be a bad logic board, and if so is there any recommendation on how to go about cleaning corrosion, or any other issue I might face instead of replacing the logic board right out?
Thanks.
