Good morning all.
I know I am probaly going to get trolled here and the problem is more than likely so evident.... but I dont seem to be able to locate the issue or what I am looking for as I am getting strange readings. So as follows:-
J7050
pin 7/8/9/16/17/18-- gnd
pin 4/13-- alternates 3.42v - 4.78v and various incarnations close to either end ( i.e. 3.42v may be 3.429/ 3.427/ 3.426 and 4.78 may go 4.47/46/48) never steady
pin 5/14 -- 3.42v static
pin 6/15-- 0.00v
pin -- nc
pin 1/2/3/10/11/2-- initial shows 12.58v then drops to 3.419v then rises to 12.58v then drops to 3.419v ongoing
even though openboardview and the schematic show 4/5 as NC there is definatly voltages there.
When I turned the board over and looked under the scope D7050 was cracked, so I replaced this. C7050 and C7060 seem OK.
Here is the issues, MBP came into me initially after having a bottle of Ribena poured over it. Refused to power on even though LED on magsafe was there. Went over the board and replaced a few components and cleaned. It then powers on with no problem with exception of the battery was not detected or charging and the fan would not spin initially, however after about 5 mins of use it did spin. Went over the voltages at J7050 and all were correct as far as I could see. A new battery ( genuine ( aparantly)) was purchased and installed. All worked fine, battery was detected and charged to 100%. The MBP even though the fan did not spin initially and did not over heat worked fine.
It has now come back again with the battery not detected and not charging, the fan issue still persists but the MBP boots and works perfectly despite these issues.
The voltages I have listed above are not the same readings as before the battery change. The reason I mentioned the fan is it may or maynot be connected to the issue.... I just do not know.
From my limited experience, I feel the issue is the SMC but I may be wrong.
Can anyone enlighten me as to what the readings should be and what I should be looking for.
Many Thanks.
