820-00840 when i open lid macbook turns on itself when its turned off

[farfan14]

have strange problem with this model. determined several problems

1) when i open lid macbook turns on itself when its turned off

2) when system is turned on and it asking for admin password if you connect charger it shows 100% and after about 5 seconds it shows correct battery percentage.both ports doing same. e.g if battery is 73% charged ,after plug charge will be imediatelly 100% and after 5 seconds 73% again

3) if you will enter admin password and than you will connect charger than it doesn't shows that 100%

4) customer also said that sometimes macbook was showing charging icon without charger connected but i haven't seen this problem during 2 days checking this macbook

• i tried change battery and also changed both CD3215

1 is expected behavior for this model. 2 and 3 are system bugs, I see this happening here all the time and there's nothing you can do to solve it as I said, it's system bug. 4 is not normal unless it shows charging icon on login screen, if it happens just on login screen, it's also a OS bug, already seen this specially when machine hibernated after battery reaching to 0%.

Nothing to worry, as machine works perfectly.
It should also turn on when you press any key.
Go to System Preferencies, if you want to make changes.

Do not prest atention to login screen notifications.

Already explained that two times.

"Go to System Preferencies, if you want to make changes."
You can see at least which options are enabled there...
