if i remove r9709 or r9708 the short goes away and i get 150k+ ohms at PPVOUT_S0_LCDBKLT. if i replace them there is no change and i did check the parts and i was getting proper ohms from them. if i pull the u9701 the short is still there so the problem is not in the u9701. where the heck...

If it is the u9600 should...

Okay thanks TCRS, i tried a re-flow and still no difference. unless anyone has any other ideas i'm going to give this one back almost fixed but unfixed.
I will look into the isl6259 area and current sensing. 8.57v on ppbus with ac only. with and without the system powered on. acok is present at 3.34v.

no the trackpad flex looks good and the trackpad itself, if i disconnect the trackpad it still does the same thing. there was corrosion in the battery connector, i cleaned that. there was corrosion on the jtag and i removed the jtag. maybe there is corrosion under the trackpad connector? i could...
