Hi,
Yes. I've tried with a good DCIN board.
Right now i don't even have PP3V42_G3H
PPDCIN_G3H = 19.9V
PPBUS_G3H = 0V, and 0.454 diode reading
PP3V42_G3H = 0V, and 0.578 diode reading
PP5V_S5 = 0V, and 0.506 diode reading
PP3V3_S5 = 0V, and 0.152 on diode reading
U7000:
1= 0V
2= 0V
3= 0V
4=...
Hi,
I have an A1932 820-01521 that enters in DFU mode, but always gets an error before the end.
Sometimes it says that he needs to install a software update (on the Mac with the Apple Configurator 2), I start the update, but at the end it says that it can not update , because nothing was found...
Hi.
After using an original 85W charger, the mac now powers on, but it dosen't charge the battery, and has no green light on the charger.
Shall i replace SMC?
Hi,
Client said that the display started going black and stopped giving image.
I didn't try new BIOS, but it seams that someone tried before me.
PLT_RESET_L = 3.3V
Hi,
I have an A1398 820-00163-5 with no image. Nither internal or external.
I have green light, CPU gets hot, have fan spin that increase RPM after a few seconds.
All big coils have voltage, but USB tester doesn't show USB activity.
Can you help?
Hi,
I haven't tried SMC Bypass (sorry, forgeted), but it powers on in SMC Bypass.
When triggering SMC_ONOFF_L, i have drop pulse at PM_PWRBTN_L, but no pulse at PM_SLP_S4_L. However, I have no green light on charger
Shall I replace SMC?
Hi,
You've asked for U7010 voltages in previous reply. I guess it was a distraction.
It seams that sometimes the mac reboots randomly.
PPBUS_G3H = 12.56V (stable until reboots)
3V42_G3H = 3.4V (stable until reboots)
PP3V3_S5 = 3.3V (stable until reboots)
PP5V_S5 = 5V, but sometimes...
Hi.
No, it's set to 5A. It reaches around 1.8A, with 3V, but I can't see nothing hot. Can it be an internal board layer (not sure if this makes any sense)?
Nothing gets hot, even increasing until 3V and consuming 1.8A.
I've removed L7560, C7593, C7592, C7590 and C7572 but PP3V3_S5_REG_R remains shorted (0.002 diode reading), and nothing gets hot even so.
