Hi,
I am not new to component level repairs but also not a pro at all. Have done some work and still learning. The machine I am talking about today is a friends 2011 MBP that I am trying to diagnose and repair. To make a long story short: All I know is that the battery was swapped for a new one and since then the machine is stuck to 800 MHz according to Intel POWER Gadget.
I know that this board need the battery for full performance. Battery is "seen" and does work. R5280/R5281 measure 2k.
Tried to swap the battery again for a known good -> no fun, same situation.
So somehow the SMC does not see the battery in a manner that it allows the CPU to work full speed while the battery is seen clear enough by whatever else to charge, run off the battery, show stats, use Coconut and os on. Seems that I am missing something. Any help? Thank you in advance!
Edit: I forgot to mention that the 3S144 ASD does not throw any sensor related problem (no problem at all to be precise).
