i removed it, i put a new one back Do I not have to do that?

Thanks!! C7111 removed. Still short on pin 3 U7100. Replaced U7100. Replaced C7111 It worked. Green light, fan spin. Boots into OSX

Post diode mode to ground on PPBUS_G3H: .142 V U7100 1: 13.77-13.99V 2: 13.10-13.75V bouncing 3: 0 4: 3.33 9: 0.03 12: 3.43 13: 3.39 15: 0.047 19: 5.08 20: 5.07 27: 0 U7100 pin 3 is 0, should be 3.2 pin 3 is short to ground in diode mode. R7110: 93K R7111: 1.6 ohm ----> should be 46K and I...

OK replaced U5110 SMC_RESET_L now: 3.40 no green light or fan and of course PPBUS_G3H is now..... 0V

SMC_RESET_L: 0V Checked at: U5110: PIN 5: 0 V ---> PIN5 does not look good 1: 3.42 R5100: 96 kO 1: 3.42 V 2: 0 V Worth replacing U5110 as a try or is this the SMC?

Intermittent green light on charger (randomly come on) with fan spin for a few seconds then off. Since then, no green light. Swapped DC in board and LIO cable, no change PPBUS_G3H: 8.19 V PP3V42_G3H: 3.43 PP5V_S4RS3: 0V U7501: 4: 0 12:0 21:0 So no enables on U7501. I though it was the DC in...

New SSD fixed problem. Thanks!

U3740 PIN 1: 3.42 2: .99 3: 3.29 4: 0.43 5: 0 6: 3.24 7: 0 8: 0 SSD getting very warm, almost hot

Liquid damage Ultrasonic done Fan spin Boots to OS X Catalina from USB attached external hard drive J3700 pins look pristine Still does not see internal SSD in disk utility I am going to try another SSD Checked caps on PCIe data lines: C3710-C3717 Any ideas? ? U3740?

OK that worked. R6119 measured 200K Changed it out and boom! USB now works Machine boots! Can you tell me why you went to the SPI termination resistors? THANKS!!!

820-00165 A1466 MBA Liquid spill Corrosion around U7870, C7870,C7871 No fan spin Replaced a terrible looking C7870---> fan spin Orange light on charger CPU VCORE: 1.8V No backlight No image No chime Fan is spinning All G3H power rails are good USB Mouse does not light up USB SATA drive...

Problem solved jumper pin 10 on U3510 to J3501 pin 17 brings back functioning Bluetooth

Can you explain what you mean by: You can also remove U3510 and bypass these pins... VOLTAGES: 6: 0 7: 0 9: 0 10: 0 4: 3.4 5: 3.4 That can't be good. DIODE: 6: 0.40V 7: 0.40V 10: 0V 9: 0.70V

U3510 1: 0 V 4:3.32 V 5:3.32 V Tried another airport card off ebay Continuity using diode mode 10 and J3501 PIN 17: GOOD so my jumper looks good 9 and J3501 PIN 16: GOOD

Boots into OS fine. Wifi present Bluetooth not available. U3510 5: 3.4 V 10:0 V 9: 0V diode mode pins 9, 10, 6 and 7 all show no short There is what appears to be a broken trace between PIN 10 and the via which I assume is the via to J3501 PIN 17 scraped away the corrosion and exposed the...

If a 2014 MBA works fine when the internal display is disconnected and an external display is used can you clear the GPU of fault and implicate the display assembly. Please understand that I am just learning and wanted to know if it was worth the trouble to swap out the screen assembly if this...

A1286, 2011 MBP 15" Boots fine. Can work for 1-2 hrs, sometimes longer. Then CPU starts to overheat --> 70C on hardware monitor A was looking for ASD 3S144 but I could not find it anywhere (I can use Google but the download sites listed are all down or expired) I tried booting with D held...

PP3V42_G3H L7095: 3.425 V (pin 2) PPBUS_G3H F7140: 8.60 V When I plug in the mag safe, green light (3 seconds), switch to orange Then fan spin This is both WITH and WITHOUT battery attached ON the DC in board, I think I identified the "one wire" circuit components...

leave it? Are you joking? Come on i posted correct info now I cut traces, you explained that to me. I did it correctly i moved to isolate it and I found a problem at Q5310 That trace leading to pad 4 should not be short I thought that was the f**ging short that I found now I want to know if...
