Installed new OS on a new SSD. Still getting this issue. When the Macbook does boot, everything works. But reboot takes time and some tries. This was the latest code
Hey,
A1708 820-00840, machine boots most of the time flawless, sometimes it takes some minutes to wake up. When it takes some time, theres an error reported, find attached. This machine gets pretty warm, in repair wiki i cant find a specific example as its not "random crashing". Inspected the...
SSD_BOOT_LB_L 1.8V
SSD_PWR_EN_LB_L 0V
STORAGE_LB_EN 3.33V
SSD_RESET_LB_L 3.32V
SSD_PCIE_CLKREO_LB_L 3.32V
LPSR_EN_LB_L 3.32
Where to check clock? PCIE_CLK100M_SSD_LB_N or PCIE_CLK100M_SSD_LB_P?
at R9420 P2V7NAND_EN and PICCOLO_VEN1 are 3.35V - is that correct?
I tried to install OS X before i opened the Thread. I just tried it again with USB Installer and there's no SSD recognized. Questionmark Folder also still coming up.
Installed J9600 metal plate. PPVIN_2V7NAND_LB is 13.01V instead of 2.7
edit: looks like PPVIN_2V7NAND_LB should be 13V?
Found R9415 P2V7NAND_DRVL_R and P2V7NAND_DRVL at 0V
.461 Diode
PP2V7_NAND_VCC is 5.107V instead of 2.7, same for PP2V7_NAND_PVCC
Hey,
820-00923 A1706 with missing SSD. PP3V3_S5_SSD is 0,785V. Just wanted to measure around Piccolo Current Sense and - everything's missing. Just to be sure, there should be U5920, R5920, R5925, C5920? Also looks like U5910 is missing...
Do i have bad schematics or is this real?
Hey, i just swaped an i9 logic board (donor MBP, drop damage) to a other case/screen. Everyting works but the screen began to flicker, on the right side its a grey bar but you can still see the desktop. So bascially i thought its a dead screen, but one time after a SMC / PRAM reset the screen...
Q7065 no short. Pin 5 is one pin on the schematics but 4 real pins on the chip, is that correct?
All pins O.L.
Pin 1-3 .373 diode
Pin 1 & 5 .427 diode
P.S. Can i use A2141 Display Panel for this A1707?
Hey there. 2017 A1707 with dead display and battery. USB charger first showed pulsing 5V - 16V in loop. After disconnecting the battery macbook booted, display is obviously dead (flexgate) but external worked.
When reconnecting the battery, USB charger begins to loop again. Found a burnt USB-C...
Lifted U9080, doesn't look corroded.
Short is still present on PP2V5_NAND_SSD1. Injected 1 - 3V. SSD gets warm at 3V, but only 30°C.
Still L9080 / L9081 0.00Ohm / .002 Diode
