Hello.
My question is: does a MacBook Late 2009 (A1342) detect and charge battery correctly even if the trackpad is not connected at all?
I have this strange question because the MacBook works fine except battery detection (X symbol) and charging and am wondering if there is a chance that replacing the trackpad will fix this. Don't want to spend too much on it as it is pretty old and could even live without battery at all but when some time ago I tried to update to El Capitan it keeps failing to install because of a division by zero crash near the end of installation in logBatteryState() function. Which is surely caused by TB0T, TB1T, TB2T temp sensors which don't work correctly (checked with Linux live CD).
I don't know where TB0T, TB1T, TB2T sensors are, but if they are on trackpad and/or trackpad cable (liquid contact indicators around trackpad show there was some liquid damage - MacBook was bought used on EBay) then in my wild theory MacBook could decide to treat battery as non detected and refuse also to charge it (the magsafe led keeps switching between green and red/amber in several second long intervals).
The MacBook was bought with dead battery but I also have two other batteries, one was bought as used, the other as original and new (but you never can be 100% sure). With this other batteries I could pull out the magsafe - the OS would go immediately to sleep - and wake up again when magsafe was plugged in again. IIRC when in boot menu I could do this unplugging of magsafe and the computer stayed on without going to sleep. When running some OS which has no powermanagment support at all the computer ran fine from battery. This worked for a while, but then probably batteries went 100 % uncharged and it did not work anymore.
The computer also has the slowdown/kernel_task throttle problem, but that is just an OS thing (Linux not affected for example) and normal with bad temp sensors and there's a workaround for this.
So has someone by chance ever seen that a MacBook A1342 with fully working battery detection and charging can be "persuaded" to *not* detect the battery (X symbol) and to *not* charge the battery simply by disconnecting the trackpad?
