Let's say someone ( .. definitely not me ... ) managed to jab a pair of really sharp micro tweezers covered in Amtech flux into their finger. What would the long term prognosis be? And if those tweezers carried a 0201 resistor deep into someone's ( ... again not me ... ) vein what might happen?

Removing J6100 seems to have sorted it - I should have really just removed/replaced it when I first noticed the corrosion. Thanks for your help with this. Much appreciated - can I get you a beer as a thank you somehow?

Ok - I give up. Lots of mentioned of people saying they did start up in bypass mode but I cant find out how to do it. How exactly does one start up in SMB bypass mode? Did I say I was vanilla / a noob / pure with this ?

History wise, no idea, an acquired laptop :-) Given to me with no more than the words 'it doesn't work'. The inside didn't look messed with, judging by the thick layer of dust. The only thing that looked corroded out of place was a bit of corrosion at J6100. Just working out how to start in...

Yup looks like a power loop to me! Pulse at L7320 CPUVR_PHASE2 = 8.5v PPVCC_S0_CPU_PH2 = 1.75 (ish) Pulse at L7310 CPUVR_PHASE1 = 8.5v PPVCC_S0_CPU_PH1 = 1.75 (ish) U1950 PIN 3 - SYS_PWROK = pulsing PIN 7 - PM_S0_PGOOD = pulsing PIN 2 - CPUVR_PGOOD = pulsing PIN 1 - ALL_SYS_PWRGD = pulsing

Well pulling SMC_ONOFF_L at R5116 (OMIT) doesn't seem to have any effect, pulses remain constant.

Yup .. so all PM_SLP_Sx_L lines all pulse to 3.2v every 4.2 seconds, the pulse width is about 200ms By triggering the SMC_ONOFF_L just pull it to ground?

Hey there thanks very much! Here are some voltages after a bit of probing. Annoying the damn fan started spinning during the probing, then stopped. PM_BATLOW_L = 3.331v PM_DSW_PWRGD = 3.341v PCH_DSWVRMEN = 3.002v PM_PWRBTN_L = 3.4003v PM_RSMRST_L = 2.734v My scope is otherwise engaged for...

Hi Bit of a noob here so please excuse the no doubt dumb questions. I?ve been working on fixing a A1466 / 820-00165 Mac Book Air and I?ve got to the point where the main power rails are looking correct but I?m not sure where to go from here. I'm getting a green then organ light from the...
