    820-3437-b green light pulsing on vcore

    Yes, when I do a bypass, the fan spins for 2 seconds, stops for 2 seconds, starts for 2 seconds, keeps repeating. pins 7 & 3 pulses as well.

    820-3437-b green light pulsing on vcore

    PPBUS_G3H - 8.56V PPVRTC_G3H - 3.3V PP5V_S5 - 5V PP3V3_S5 - 3.3V PP3V3_S3 - 3.3V PP3V3_SUS - 3.3V PP5V_S4RS3 - pulsing, vcore pulsing as well, no short to ground. I checked all the SPI traces and resistors, re-programmed bios with clean ME. Any idea what to do next? No water damage just...

    820-2936 green light no fan spin

    The board stays on in normal mode, minus the vcore of course. r7402, 7mv on pin 1 and 12.60v on pin 2. Even in SMC bypass, it measures the same Also, resistance is 55k, which should be 90.9k, so I removed the resistor out of the circuit and it measures 90k to be sure it's good.

    820-2936 green light no fan spin

    3V3_S5/SUS without bypass is 3.3v and SMC bypass is 3.3v as well. AVREF_SMC is 3.3v with and without SMC bypass I get voltage on all coils except the PPVCORE_S0_CPU_PH2 or PH1 and PPVCORE_S0_AXG_R in normal and in SMC bypass Also noticed ppbus_g3h is 12.6v normal but in bypass it's 12.33v, I...

    no pulsing PM_SLP_S4_L it's a steady 3.3v, SMC bypass board stays on "fan stays going" I do get 3V3_S5 and 3V3_SUS 3.3v each.

    820-2936 green light no fan spin

    No pulsing all, when charger connected or triggering SMC_ONOFF_L, SMC Bypass, the fan does come on but no boot or chime. Is it something with the bios/traces or clock signal?

    820-2936 green light no fan spin

    Hello, This board was liquid damaged, repaired and working. Somehow a screw dropped on it sometime after, no idea how they pulled that off. Anyhow, I was missing PP5V_SUS and Q7840 was replaced, PP5V_SUS came back. Sometimes the fan tries to move bit stops, it's not even a quarter spin, it's...

    820-3115-b liquid damaged - camera not working

    Hello, This board was liquid damaged, caps: c5025, c7526,c7525 was covered in liquid stuff. Also, U7200 was covered as well. Replaced the caps and cleaned up the area and had to replace u7200 as it was blown. Board boots and works fine all expect the camera and for some reason when I try to...

    Can HWMonitor be trusted? System total taking 47W, CPU VccSA 7A, GPU Die 236c insane numbers.

    820-2850 no image, no chime

    It reports both GPU's the intel and the GT 330M, I am going to assume there is no fix other than disabling the NVIDIA GPU via some hardware mod?

    820-2850 no image, no chime

    Before swapping out cap: Do you note VCORE dropping 0.2-0.3V few seconds after start? - yes, 1v then drops to .8v Is better to confirm USB activity with OSX pen drive, with LED Link; if flashes OK. - I have a USB stick with a LED on it that contains High Serria install, no flashing from it...

    820-2850 no image, no chime

    Hello, I have an 820-2850 with no image and also doesn't chime. Using 85w MagSafe official apple charger If I take the memory out, it will beep and if I connect a mouse, it does light up. I have tried another display as well to rule out a bad LCD. No liquid, the board just stopped...

    UPDATE on this and how it was SOLVED. Short version, swapped SMC, firmware now updates and running on the newest OS with no issues. Long version: I found a way to manually push firmware updates to the BIOS. You can get the firmware from unpackaging (Program such as unpkg) the install...
