Battery / SMC issue..?
Recently I bought a very cheap 2011 MacBook Pro that was liquid damaged - only bought it because it was still running so assumed it wasn’t too bad.
Keyboard was definitely dead so I replaced with a brand new one now it works flawless. Also replaced charging port after reading here ( MacBook Pro not detecting battery (even after logic board replacement)) it might be faulty but looking back it was a waste of money as it didn't make any difference.
Then I bought a 85w charger as the one I had was 60w - actually made money with this as the brand new 85w cost me $20 and I sold the used 60w for $40 :)
Then I tried different batteries but system still shows ‘no battery available’. Also tried the batteries on another MacBook I had here and they were working fine and system showed ‘normal’ though with a bit over 1000 cycles.
When I unplug the charger the screen goes black but the laptop keeps running for a few seconds before it dies.
Charger keeps green light on all the time - it won’t go amber at all either the 60w or the 85w and regardless of laptop on or off.
Unplugged the BIL cable as it was suggested in another post here ( MacBook Pro not detecting battery (even after logic board replacement) ) and still no difference.
Now here’s the interesting part: when I bypass the SMC (unplug charger, hold power button pressed, plug the charger back, keep holding power button for 5-10 sec then let go and press power again to turn it on) the fans go loud but everything works fine even with the charger unplugged meaning the battery is holding charge and it does power the laptop even though system still says ‘no battery available’.
Here’s a video:
I assume it’s a faulty SMC but I spent a lot of time online and couldn’t find a picture so I don’t know how it looks like or where it is located on the logic board.
So the plan is to either try to fix the SMC (once I know where it is - anyone has a picture?), try to replace it (unlikely unless I find someone with micro-soldering to do it) or try to keep bypassing the SMC and force the fans to slow down but I can’t slow it down via software already tried. Maybe some Terminal command could do it but which..?
Anyway has anyone had this issue and successfully fixed it?
Any suggestions would be appreciated :)
