BATT+ to BAT_ID would do the trick.
I'll put money on the EC being half fried.
What exactly do you mean by "do the trick?" Am I supposed to short these pins to get it to work or is that what would have shorted the chip?
Also, what chip is the EC that you are referring to?
Shorting pins again isn't going to fix anything..
The EC is the Embedded Controller, what Apple would call an SMC. The various data connections from the battery run there, and it will not be even remotely tolerant of being shorted to BATT+. And it's one of the parts which can just turn the laptop off by itself.
Please be positive of which schematic applies to your laptop.
As mentioned in other posts from the other thread - at first guess from the supplied schematic), I'd be guessing that you shorted pins 2 & 3. The zener might save you (depends on the breakdown voltage).
No other adjacent pin numbers look like they'd do anything permanent - unless the pin numbers are staggered somehow.
The bad news is that Pin 3 - BAT_ID goes directly into
U22 (Winbond LQFP 128 pkg)
Which ;ools like a general mainboard controller for all non CPU requirements.
It doesn't bode well for a quick fix unless Santa was smiling on you. Check the zener diode, or replace it - you might get REALLY lucky...!
