Thank you also Aprendiz.

Probably the U7701 then? I've been using pulled ones reballed with an iPhone stencil. I have some on order, but impatient. Thanx Philip, I'll try this jumper ! And thank you for clarifying the voltages ! ! !

So what should it be boosting to? & what should BKL_PWM be?

R7704 is 1.46

21V, isn't that boosted?

Thank you Duke. I will try this : )

Macbook with no working trackpad or keyboard. Did a battery unplug and all is working fine. Next day, again, not working. Any ideas? No clue on where to start if its working. I've seen the IC in one once with a cracked IC and changed it and all was good. But this is kinda strange.

I got another one of these. Keep seeing it here and there. No CAM_EXT_LDO_EN. Weird.

Yes, I thought it was very strange because I never seen anything like this in any of Louis's videos. Once again I thank you for your assistance Duke : )

No missing components never opened before. I seen nothing burned out.

I am curious though on what your thoughts are.

There was no water damage at all. The paranoid customer just picked it up, so no worries. I am taking mental notes and learning something new though : )

I do get 5v on the pp5v_s5, I get .218v on pp3v3_s5, and nothing on the s4's. So I am guessing that I need to check my pp3v3_s5 rails?

& this time I experimented by no battery holding C4810 plug in battery then power, wait 10 secs, release, wait 5 secs, then hit C4810 for 1 sec and getting 12.25 at F7140-2.

With the battery plugged I get 12.86 on F7140-2 after SMC Bypass. Without the battery I get 12.56 and no pulsing at R8141-2. This is a new battery, and same thing with the old battery. I am doing the SMC Bypass by shorting C4810 with tweezers on each side. I am holding for 10 secs, then I plug...

I first tried by shorting C4810, and then assembled and tried that way too. First time I've heard about SMC Bypass. Found some things online about it. Never knew about it.

Ha, ha. Sorry Duke. I have no idea either. I tried a couple of times. I even read for further directions online. I'll try it again and report back. I know its simple, but have no clue what I'm doing wrong : )

.................

It is 13.0V at R7005-1.
