Hi guys, This 820-2915 came in with green light and most voltages present, I say most cause since its not powering on something surely is missing. It seems it was LD through the USB ports side - no extreme corrosion present - I UC it before anything else. PPBUS_G3H at 12,5V PP3V42_G3H at3,41V...

@probe 122, SMC_ADAPTER_EN is high at 3,41V. @probe 1083, PM_PWRBTN_L goes from 3,41V to 0 when I press the on/off button. sorry for this I was hoping I could go through it more autonomously.

it does not. measured at R7812... also checked continuity to R7810, both resistors at their nominal values.

so PPBUS_G3H: 12.5V, PP3V3_S5: 3.25V, U7100 area nice and shiny...

Hi guys its me again. This one has no turn-on pads so you have to use your tongue. last joke before giving up - there is 3.3v on R5710 but nothing happens when I take this to ground. It was ld and gave it a bath, green light came on after gently reflowing the SMC with some flux. L7220 seems...

ok diode measurements to ground (new ones) pin1: .428 pin2: 0 pin3: .544 PP3V42_G3H present, green light ok - EDIT: I dont let it stay on for long since D6990 gets really hot. F7040 diode mode starts at .170 and rises slowly to .380 (keeps going one by one but Ill kill myself before it halts)...

OK I took this out of the box again for another try.. Measured R7005 at 170ohm instead of 20ohm and replaced it. PPBUS_G3H is at 1.2V and L7030 gets REALLY HOT in about 30sec, diode measurement .414 - but EVEN hotter is D6990 in 10sec time, which I replaced to no avail. Diode measurements at...

PPBUS_G3H, no batt, 1,9V now (was higher when I started messing with this board but fluctuating if I remember correctly) C7050, resistance mode, 2,9ohm C7020, resistance mode, 20ohm

apologies for that: https://www.youtube.com/watch?v=pXYScevrZHU - should be ok now thank you for your suggestions will do some testing today..

[SOLVED] 820-2936 works only from battery, also not charging - "nice" 40sec video included. Hi guys (again), This one has been giving me hard time for a while now. It would only run from battery and after some testing with the charger connected it went kinda FUBAR. I replaced isl6259 and...

Hi guys, Having UC this one (was pretty messed up) I replaced U6990 and got a green light (at least thats how I remember it and in a hurry noted on paper - since this board was written off for a couple of months) but the system is still dead. Measuring around I discovered that my ppbus_g3h was...

Thats a very interesting topic regarding ME region. Luis mentions that the various ME guides found online are crap which hopefully means that he ll make one that corrects this situation :)))

I don't at the moment but knowing this I can ask the customer to spend some extra dough on that.. I will also let him know that there is a slim chance for re-examining the board incase it does not charge the new bat. thank you louis.

Hi guys, As this is my first question in the forum Id like to say hi to all and thank you in advance for your support. I got a 820-3536 which was liquid damaged and would not turn on. After UC and replacing ISL6259 (followed the rabbit hole) the system boots fine and works as expected but: 1)...

Hi, So proud to be here and so happy to have stumbled upon Louis and his videos on Youtube. This is not a "kiss your ass" post but a "thank you for showing me the way". I had, until recently, a declining business in the computer repair sector which still exists under a different administration...
