Computer came in very slow and laggy. Like when aftermarket battery or no battery is being used, which in this case it was aftermarket and not being recognized. So, I ordered a new battery and a week later installed it. Powered on the computer with the new battery and it went right into OS. Showed battery charge percentage at 78 percent and functioned completely normal. Checked sys info and it showed charging as well. I then turned off the computer and screwed everything back in, only to find out when I went to boot it back up, it again would not boot off battery and was lagging. Here is what I have after removing the board.
I found a tiny bit of corrosion on C70221. I replaced it and checked 27/28. Resistance was all good. Also checked 17/18. Everything good there as well to be safe.
Im getting 11.54V on PPBUS with only battery connected. Computer will not turn on like this.
When charger and battery connected. Computer boots very slowly into OS. battery icon is full black with lightning bolt in it as if its charging.
Also in sys info/Power - I get this https://photos.app.goo.gl/VsfVCp7XNKBKvzWLA
