Mac Book Battery Not Charging Correctly
I am having problems with my newly bought Mac book Pro 13”. The battery is not charging when the computer is on. But when my computer is asleep or booting, the battery will charge the usual way. When the computer is on, the battery will drain and a warning message will be shown that there is no power source.
A hallow insight proves some results that until now are not working even when trying. Some of the steps that I have tried so far are:
-SMC reboots (l-shift + option + control + power)
-Manual installation of Thunderbolt
-Used a tested working power adapter.
I tried the power cord on my Dad's Mac book and it worked. I am running OS X Lion. I thought the problem must be software related, and then I found out that the problem however prevails both before and after installation of Lion.
I am trying to update Thunderbolt Software. But the update won’t continue without plugging in the power cord. But I guess I was wrong with it. It really feels good to throw a question here even though I can conduct additional research. Anybody who has the ideas please tell me.
