I am guessing those have to be harvested?

Ok Pin 2 0v Pin 4 0v Pin 6 3.28v

Ok, C7933 replaced, With U7890 removed and pins 4&6 connected, PP3v3S5 is 3.28v When I put U7890 back, PP3v3S5 is 0.01v Is it U7890 then? or does it mean something else?

Hi I simply don't know what I don't know. I've signed up for electronic engineering course as I am getting more and more of such jobs. Thank you for bearing with my pure ignorance. Removed U7890, joined 4&6 L7690 1.08v as it was plugged C7933 went red hot - removed it, line is not shorted, I...

I did just that. All readings are diode mode to ground, red to ground Some of the coils would show out of range so I had to change the scale Attached picture of my multimeter

R7862 3.2v on both pins Yes, it was the beeps that I considered shorts 2k scale L7900 Pin 1 .046 Pin 2 .046 L8060 Pin 1 .061 Pin 2 .061 L7370 Pin 1 .009 Pin 2 .009 L7220 Pin 1 .006 Pin 2 .006 L7210 Pin 1 .006 Pin 2 .006 L7410 Pin 1 .002 Pin 2 .002...

PP3V1_RTC 3v R7822 no matches found C7822 doesnt exist either I hope its a typo Test starting in SMC bypass mode. - I've tried that with/without battery - doesnt seem to make any difference. I dont have a test chassis thou so maybe keyboard is bad but thats a long shot. Lots of shorts on coils...

Ok, thanks SMC_PM_G2_EN 3.3v PMIC_SHUTDOWN_L 3.2V U7890 Pin2 0v Pin4 0v Pin6 3.3V

Thank you I hope I checked the right ones Pin 16 PP5V_LDO5V 4.9v Pin 39 PP3V3_LDO3V 3.2V Pin 46 BANJO_FBLDO1 0v Pin 73 BANJO_VINLDO1S 0v The rest is just copies of the LDO5V or LDO3V You have asked me to check 7 of 10 if I understand correctly so I am obviously missing something.

Thanks Nothing on 3V3_S5 Please advise, I cant seem to work out where 3v3_s5 originates from

Hi Unit stopped turning on, no visible liquid or other damage Getting 5v then goes up to 20v and stays there forever but pulling only 0.01A checked a few things PPBUS_G3H 12.99v 3V3_G3H 3.39v L6995 to ground Pin 1 277 Pin 2 276 (is it too low?) U7000 P_IN 20.1v AUX_DET 5v VDDA 12.9v...

pins 28-30 nothing during during chime LCD_PWR_EN 0v LCD_5V_EN 0v measured during multiple boot cycles L8300 under 1 ohm so its bad, I understand this happens due to screen connector short, anything I should check before replacing L8300?

Thank you Power present on pin 3 but nothing on 28-30

oops, you are right, its 820 00163 A

USB seems to work, I actually had a screen come up for a few seconds, showing the login screen and suddenly went black with all else seemingly still on

As per title, no visible damage, no liquid residue, nothing that I could see. Tried with an external screen via HDMI and couldn't get a picture either, Please assist Thank you in advance!

Hi, Yes, those signals and voltages are still present yeah, that charger is a replacement so no, not original one u7100 1 - 13.87v 2 - 0.31v 3 - 0v 9 - 0.03v 12 - 3.34v (its back!) 13 - 3.36v 14 - 0v 15 - 0.04v 17 - 0.5v slowly draining down 19 - 5.05v 20 - 5.05v 27 - 0.5v draining down to 0v...

PPBUS_G3H - starts at 0.5v then drains down it seems, it was fine yesterday so not sure if I done something to affect it No liquid nor any visible corrosion near SMC or J6100

Hi No light on the connector no fan spin. Tried with known good I/O board found signs of corrosion on c0895 and the test pads around it but after cleanup the lines seem to be ok still no power PPVRTC_G3H - 3.39V RTC_RESET_L - 3.39v PCH_SRTCRST_L - 3.39v PCH_INTRUDER_L - 3.39v PCH_INTVRMEN -...
