Hi,
I have been asked to replace a broken LCD on this Macbook. I did several screen replacement on older Macbooks, but never on one from 2020.
My question: on these models, are the screens "paired", and there is a need to update a software after the replacement, or is it enough to unscrew and...
Hi,
I have few trackpads from Macbook Air 2013-2017, some clicking but no pointer moving, other without reaction. They are not apparently water-damaged. Is there any way to repair them? Any board view available? Or better to forget about repairing them?
Hi,
This board chime and I see the blinking folder.
Internal SSD is not detected, I tried 2 different, with Big Sur and Yosemite.
External SSD is not detected either, tried with 2 different
I am unable to do a PRAM reset, neither from internal keyboard or external keyboard, even with internal...
Hi,
On this board I replaced the LCD connector and the LCD (from China).
Apple test (D key) says no problem;
ASD EFI 3S156 is fully passed;
ASD OS 3S156 shows the attached error.
ALS, camera, work fine.
What can provoke this issue? I checked again the LCD connector, all pins look good
Hi,
This board had few small spots of water damage, I repaired them, and now I have chime, orange light on charger, but no display on mini display port. Internal display is ok, blinking folder.
R5350 and R5351 are ok, 2 kohm, voltage on all their pins is 3.4V
PP3V3RHV_S4_TBTBPWR_F = 3.3V...
Hi,
This I/O board for Macbook Air is powering the board properly, but no green or orange light appears. Is there any schematic available for it? I cannot find one on internet. Or any clue what to look at?
Hi,
My scope can save waves to csv, but not directly in jpg. I would like to view back these waves in Windows to put them in documents, so in jpg for example.
I tried Wave Editor, but it seems limited to 2048 samples and is also globally very limited.
TTScope does not accept csv files.
Any idea...
Hi,
This board is not charging the battery (green light always present) and in OS X it says: Battery not available. If I cut DC IN, the board stops.
I tried with another good battery, same issue.
BATT_POS_F=12.15V
SYS_DETECT_L=0V
SMBUS_BATT_SCL= moving between 34 and 125mV
SMBUS_BATT_SDA= moving...
Hi,
I have this old board, with no WIFI.
L3401 was water-damaged as well as 2 pins. I replaced it, but one of the pin is completely destroyed, and it goes directly to the processor. See photo : do you think it is possible to scrap until reaching a trace, and then solder to L3401 with a wire?
Hi,
This Macbook is working fine, ASD 3S144 showed no issues.
I tried to install High Sierra, but the installation stopped and I came back to the initial installation menu.
Then I managed to install El Capitan, it updated the BIOS during the installation. I downloaded an update from Apple, and...
Hi,
This I/O board from a Macbook Pro Retina 2015 is preventing the main board to start because it's shorted on PP5V_S4.
Do you have a schematic for it? I cannot find it on internet.
Can I inject some voltage on PP5V_S4 to find the short?
Hi,
This board boots fine, charging fine, but when charging HWMonitor displays Battery current around 253A.
I checked on another working board, same result. Is this a bug with HWMonitor?
I have this board which works fine with one memory slot, but does the 3 beeps if I insert any memory module in the second slot. I don't know from where to start. I have read about a testing memory card which I don't have and don't plan to buy given the age of the board. What could I do?
Hi,
On this board, initially PP3V42_G3H and PP1V2_S5_SMC_VDDC were shorted (voltage was 2.6V then). I had to remove SMC to figure it out, which I soldered back, but still PP1V2_S5_SMC_VDDC was at 0V.
So I have now:
PP3V42_G3H : 3.4V
PPBUS_G3H : 0V
PP1V2_S5_SMC_VDDC : 0V
PP3V3_S5_SMC_VDDA ...
This board has no fan, no green light on charger.
PP3V42_G3H=3.45V
PPBUS_G3H=0V
On U7000, pin 2 : CHGR_DCIN=0V. I checked D7105, in diode mode I have 2.85V in one way and 2.27V in the other, so I believe it is dead (values on a good one: 3V and 0.25V)
On U7000, resistance on pin 2 is 2 ohm...
Hi,
It is a clean board, which gives no errors when running Macbook internal diagnostic (D key). WIFI and Bluetooth work fine.
On the other hand when I run the ASD 3S162, I got errors on load test and airport test, see attached (ignore the first sensor group error, I simply did not have the DC...
