Injected 3.42v but it’s drawing only .14 amps and nothing heating up. Am I going wrong somewhere?

L6995 short to ground. Removed L6995 and PIN 1 - 0.615 and PIN 2 - 0.005 (Short) in diode mode with red to ground.

U7000 voltages: 1 – 0.04 2 – 15.76 3 – 4.0 9 – 0.33 12 – 0.10 13 – 0.40 14 – 0.19 15 – 15.77 17 – 2.42 19 – 5.0 20 – 4.79 27 – 16.7

Hi, Need help with a A820-2936-B board. Came with no charging issue. Working fine on battery. Changed U7000 and now no green light and no fan spin. 3.3v and 5v rails missing. Where do I start..

Computer has no liquid damage power light goes green then orange, no fan spin though. Found a short on PPVCC_SO_CPU. Meter in diode mode Resistance to ground is zero. Is it a short CPU or can i check for something else before I give up. Thanks

Replaced R5171 and U7701 and got the backlight. PRAM & SMC reset took care of the slow booting. Thank u.

What do i check for some help will be nice... But will have to wait till i get the new chip.

Removed U7701 and XW7720 is fine. D7701 pin 2 to U7701 A5 link is perfect. Anything else needs to be checked while U7701 is removed? Ordered a new LP8550 and should take a couple of days.

SMC_LID measured on R5171 Pin 1 - 0.65 mv. Missing...Changed the LIO board and flex cable. Swapped the board on a working machine and same issue. XW7720 check is pending as i will need to remove U7701. R7704 Pin 1 and 2 both show 0v. In the meantime, if this helps...

Awaiting reply please...

Another thing i noticed... With a flashlight at the back i can see the machine boot but it is extremely slow and keyboard and trackpad both not working. Power on off button is unresponsive and even with a battery connected it boots up without pressing the power key. Am i looking at SMC issue..

Hi, Need help with a board random backlight issue. First time i started it worked fine. Restart and no backlight. Now it's no backlight always. Checked the following and noticed 2.8v missing at PWM Pin voltage at the 2 Pin of the resistor R7704. Measured the VIN voltage through capacitor...

Wow... changed the charger and bang... Fan spin and looks like it's solved...... Thank u...

PM_DSW_PWRGD - 3.42v measured on R1451 Pin 1 PCH_DSWVRMEN - 2.7v measured on R1450 Pin 2 PM_BATLOW_L - 0.36mv measured on R1410 Pin 2 SMC_ADAPTER_EN - 3.42v measured on R5185 Pin1 I don't have a scope so this is the best i could do with my multimeter...

PM_RSMRST_L - steady 3.18v on R8133 Pin 2.

No pulse after triggering it several times.

PM_SLP_S4_L missing on R8179 Pin 1.

3.42v and drops to 1v

3V3_S5 - 3.34v measured on C8130 Pin 1 3V3_S5_SUS - 3.34v measured on R8133 Pin 1

Hi, Need help with a A820-00165 board. Green light and then goes amber but no fan spin. Came with a short and changed C7375 to eliminate the short. Replaced F7140 and i get a green light and then it turns amber but no fan spin. PP5V_S4RS3 missing in L7520. What next...
