Hi guys,
The board stuck in an SMC_RESET loop, keeps on restarting every 2 seconds. Power pads don't work (shutting it down I mean). Had water damage over the U5750, U7000 area. Both were replaced.
Concerning voltage, everything seems to be right and present. A hint anyone?
Thanks
I assume this was measured on battery else PPBUS is way too low.
PP1V05 is of course not correct at 0.8V but makes no sense as pp1v05_s0_cpu_vccpqe is directly connected to it......
PPBUS was measured with the charger connected, no battery attached.
My bad, I meant:
ppvcore_s0_cpu=1.1v , ppvcore_s0_axg=0v , pp1v05_s3_cpu_vccdq=1.5v , pp1v05_s0_cpu_vccpqe=1.05v ,PPVCCSA_S0_CPU=0.8V
I guess you meant those 2 current sensing circuits, resistors R7020 and R7050 - those are measured at 0 ohm, as they should I think. R7005 is measured at 20 ohm so those look to be alright
Thank you. One line from the two was cut and fixed. Now PPBUS measured at 12.7V, the device finally runs.
It is getting into sleep mode randomly and ASD shows only one error with VP0R sensor, which is measured too low
